Connection String Help

Howard Bennett — Wed, 14 May 2008 13:58:09 GMT

Not only am I new to StrataFrame AND Web Dev AND VS - but also to SQL :blush:...needing a little help on the connection string. I've copied the connection string from one of the wizards - but getting this error upon adding it to my global.asax - "Unrecognized escape sequence."

Here's what's in the Global.asax:

DataLayer.DataSources.Add(new SqlDataSourceItem("", "Data Source=SQLLR01\SQLLR01;Initial Catalog=PTPlusData;Integrated Security=True"));

Thanks again for helping the new guy out!

Step to create web form in SF

Chan — Sun, 11 May 2008 06:29:11 GMT

Hi,
Is there any tutorial about creating web form in SF?
My company just purchased SF for web app. My colleague couldn't find much tutorial about creating SF web app. At least provide steps to create something similar to create web sample; how to use certain SF web control

I already used SF for windows based dev for a year. Myself also facing the same problem when I try it out. Even though, I could easily find the answer from forum such as connection string and web service. However, for beginner, they will go thru help file before forum. They won't go thru windows based app tutorial (as most usage are same for both) because in their perception web project tutorial should cover them as well.

AFAIK, there are couple of companies used to evaluate SF for web project. However, they just decided not to use SF for web because they couldn't get much web sample and tutorial. Since hey have difficulty to start so they choose to aborden it.

Missing Global.asax?

Howard Bennett — Fri, 09 May 2008 09:55:45 GMT

I'm getting an error about the DataSourceKey is not defined...

I did some checking on here and in the sample app and found that there is a global.asax in the sample app that I don't have in my app. Additionally, looks like that's where I am supposed to setup the data connection.

So, here are my questions...

Do I need a global.asax and what is it for?

If it is necessary, should it have been added when I created the project?

Lastly, if I add one, will that take care of my DataSourceKey error?

Thanks again for any help!

Steps to Setting up a BO in a WebForm

Howard Bennett — Wed, 07 May 2008 14:09:03 GMT

Okay...I've searched existing messages and tried to figure this out on my own...with no luck!

What I'd like to know is how to add a SF BO to a webform.

What I think I understand is that I need to create a BO in another project and reference that in my webform project. I can create the BO - but - don't understand what to do next. How do I reference that and then how to I add that to the webform so that I can bind textboxes to it?

Can someone help me understand this a bit better?

Thanks - HB

P.S. Looking forward to seeing some of you in Amarillo in July!

Custom fields don't show up in addbrokenrule list

Marcel Heitlager — Fri, 25 Apr 2008 04:23:10 GMT

Hi,

I have some custom fields in a business object that are used to process a credit card payment. The information isn't stored in database but does need to be validated, and then passed on to a processor.

They are all required fields, and if skipped the error pointer shows up on the form. But when I do custom validation under CheckRulesOnCurrentRow the error pointer won't show up on the form. And I can't select the field from the Addbrokenrule list either.

How can the form identify which field had the error so the error pointer shows up?

Thanks,

Marcel

P.S. -- as a side thought, is it possible to use your business objects with custom fields only? (Nothing stored to database) It seems to have problems with two-way binding, especially when the custom fields are validated, because it can't find the tablename. Just wondering since now I don't save data now, but later however might need to. Just tried to get out of setting up database right now.:blush:

Web site development and using extensive Search

Doron Farber — Mon, 21 Apr 2008 10:11:41 GMT

Hi All,

I need to develop this kind of web site http://www.PeopleFinders.com. Is that possible to use the SF framework for this type of web site development?

Is that possible to use the Role Based Security for this development? When the user logs in I will to validate his/her account as for starters.

Or like in this page a) https://www.peoplefinders.com/RegisterPF.asp or this page as well: b) https://www.intelius.com/createaccount.php?ReportType=

I need to enable the user to create an account and after the credit card was validated, then save that record. In the above particular page the account is good for 30 days!! How the SF will handle that?

Also I need to perform a Search for people in several data bases while each one could be a 100 to 200 GB. Obviously it will be partitioned and then display the data for the user. Is there something in SF that can be utilized for this kind of Search?

In short I need to know if your Framework can help me in anyway for this type of web site development?

Thanks,

Doron

Error: The DataSourceKey [] is not defined.

Larry Tucker — Wed, 16 Apr 2008 19:25:01 GMT

I'm getting the error (below) when run on my production website. The app runs fine on my development machine. As a result, am stumped as to how to debug it.

The SaeWeb project is referencing my SaeBOL project for business objects.

On my dev machine, I can see that my Global.asax.vb is creating a DataSource correctly with "" key and correct connectionstring:

[codesnippet]Sub Application_Start(ByVal sender As Object, ByVal e As EventArgs)
DataLayer.DataSources.Add(New SqlDataSourceItem("", _
"Data Source=tcp:sql2k513.discountasp.net;Initial Catalog=SQL2005_386891_sae; User ID=*****; Password=*****"))
End Sub[/codesnippet]

My SchoolBO has a "" as its DataSourceKey.

Much to my amazement, when run on my development machine this web page is actually connecting the the production SQL database at the web host.

Not sure what might be missing in the installed version on the website. Any help much appreciated.

Error: Could not load file or assembly 'MicroFour StrataFrame Base, Version...

Larry Tucker — Mon, 14 Apr 2008 16:30:45 GMT

Hi,

I'm getting the following error on a simple "Hello World" SF WebForms project when I publish it to a web hosting service:

Could not load file or assembly 'MicroFour StrataFrame Base, Version=1.6.0.0, Culture=neutral, PublicKeyToken=99fe9917f71608a7' or one of its dependencies.

The web page runs fine on my development machine. If I build a similar simple app outside of SF using pure VS2008, it works fine on the web hosted site, so they apparently can successfully host .NET applications in general. I see a similar post in the WebForms forum from a year ago but don't think the solution is relevant now.

SF + DeveXpress

Manually Setting Selected Value and Error Trapping

Cyrus Welch — Tue, 08 Apr 2008 14:22:19 GMT

I'm running into a problem with manually trapping issues with situations where the value stored in a field is not in the list of values in a dropdown list. With a normal ASP dropdownlist control I can use TRY CATCH and handle it just fine, but with the strata frame dropdownlist control it doesn't seem to trap the error and I end up with an unhandled error. Since our users can edit the dropdowns in the system, they can remove codes used in the past (even though we heavily recommend against it, they demand the ability), VFP just gives them a blank in that situation. I need some way to do the same type of thing in the browser, or at least not have the application crash when it hits one.

What can I do to avoid this (can't use the native data binding since we bind to different tables at runtime depending on what the user chooses to view/edit)? It's so nice to just setup a method in a business object to populate the dropdown and such, but if I can't solve this I don't know if I can use the strataframe dropdowns, much as I want to.

This is with version 1.6.1 btw, being actually in testing for release (which is how we found this) is not a time to move to 1.6.5 even if it's a likely fix for the problem.

Unknown IIS Change Halts (Some) Client Scripting Functionality

Bill Cunnien — Tue, 01 Apr 2008 07:20:50 GMT

I have been working on this for nearly 24 hours and still have not been able to discover the solution. I am turning to the knowledge in the SF collective to see if anyone has run into something like this before.

Something changed on our IIS yesterday that brought everything to a screeching halt. One of the main errors that I received was this one:

Invalid postback or callback argument. Event validation is enabled using <pages enableEventValidation="true"/> in configuration or <%@ Page EnableEventValidation="true" %> in a page. For security purposes, this feature verifies that arguments to postback or callback events originate from the server control that originally rendered them. If the data is valid and expected, use the ClientScriptManager.RegisterForEventValidation method in order to register the postback or callback data for validation.

I added the tag to the web.config file (as the error suggests) knowing that this is an intranet application and I am comfortable doing this...the app began working again; however, not everything works. Most pages will not run local scripts. Some pages do not run server scripts (from postbacks). I am completely baffled as to what is going on. I recreated the virtual folder...I even moved the entire app to another server...the same thing is happening.

I am really hoping someone here can shed some light on this. Some of our critical systems are involved. Many are breathing heavily down my neck ready to pounce on me.

Thanks!
Bill

PopulationDataSourceSettings Dialog Not Populating Business Object Types

Jared Ewald — Fri, 29 Feb 2008 14:48:38 GMT

Hello to all. I am working on a web application that needs to use a StrataFrame dropdownlist control that is populated by a business object. When I click on the "..." button to bring up the dialog for the PopulationDataSourceSettings property, the window does not populate with the list of business object types and thus cannot be used to set the population settings for the dropdownlist. In the same project a couple of days ago, this dialog (and the same one for the ListView control) used to populate with the business object types correctly. Any ideas as to why this no longer works correctly (a setting, missing lines, etc.)?

Thanks!

Listview error in 1.65 web app

Mark Dowlearn — Thu, 14 Feb 2008 23:14:13 GMT

Hello -

I'm just starting a web app in 1.65 and was doing some 'fooling around'. Inserted a listview into a page, and after setting the population settings using a registered BO, received a design time error message that "an unhandled exception has occurred. MicroFour.StrataFrame.UI.Web.WebListViewPopulationColumnCollection must have items of type MicroFour.StrataFrame.UI.Web.WebListViewPopulationColumn." There was more, but in essense it was saying that instead of getting the type it was expecting, it was getting a populationcolumn of type System.Web.UI.HtmlControls.HtmlGenericControl.

The project built successfully, but yield the following error at runtime:

Parser Error

Binding controls to business objects at runtime

Cyrus Welch — Fri, 08 Feb 2008 17:56:10 GMT

I'm running into an area where we need to bind the strataframe controls to business objects at runtime. So far it doesn't seem to work at all, but I admit I might be doing it wrong.

Here's the situation. We have a meta-table of services received by clients that contains all the services they receive, but only core elements of this information. Then each category of service has it's own table which contains all the elements for the service. When creating lists, the meta-table (we refer to it as an intersection table actually) as ALL records for all service categories are contained, so we can show ALL services received. But when editing we edit the parent table, and then mirror any changes to fields also contained in the meta/intersection table from the parent on save. We want to use the same webform for most of the service types, and this works fine if I manually bind the data over (manually put the data into the control and manually read it on saves, but if I try setting the business object properties at runtime they don't seem to work. I can work with this ok, but I would prefer to let the framework do all the work rather than me. It would be far easier if I could just set the properties on initial load of the form and let everything else happen automagically. Is this possible? And if so, what am I likely to be doing wrong?

PS: some portions of the form we add controls to dynamically, so that depending on the parent organization and the service category the overview part of the form is standardized, but the detail portion is defined within the system. This part is working fine, it's just the dynamic binding I seem to be having trouble with.

Null Dates in Webforms, How?

Cyrus Welch — Thu, 03 Jan 2008 15:37:32 GMT

How do I properly use null dates in a webforms application? When working with null dates I get data binding errors on postbacks. We use nulls to at least have a nominally empty date field but can't seem to get it to work in webforms. I searched mutiple times and can't find any references to what the best way to do it so that customers won't see a date when entering data if the field is not supposed to have a date in it yet. I've tried the return alternate using #1/1/1800# and then that shows in the textbox on the screen, I could live with the return alternate concept if it just didn't show in textboxes and listviews.

Is there an easy way to do this or do I need to not bind the data and handle it myself? (which is what I'm trying to avoid).

Using DataBaseMigrator class in a web form

Keith Chisarik — Wed, 16 Jan 2008 15:25:11 GMT

How might we do this?

The third parameter is of type ISynchronizeInvoke, in the samples that I used to test it was set to ME which equated to the form, this doesn't work in a web form. I don't need it to do more then one database at a time, just apply a DDT package to create a single new database from the metadata via a web form. I am OK with using a desktop app to update multiple databases later.

Thanks.

Adding extended control to WebForm

Kari Paukku — Fri, 28 Dec 2007 17:46:06 GMT

Hi,

I have extended a SF control - basically just copied the SF Button control and named it to MyButton. It complies ok (no errors). The question is that how can I use it in a WebForm as the control doesn't appear in the Toolbox (as is the case with WinForm).

Cheers,

Kari

ps. A WebForm example would be cool - is there one...?

SF, Ajax and (Telerik) Rad/Ajax controls working together

Kari Paukku — Thu, 20 Dec 2007 15:27:18 GMT

Hi,

new to ASP/Ajax, Telerik and SF when used with WebForms could you provide some advice on what would be the best way to get started. I guess the most difficult part is how to handle the callback when the data in the web form is populated and updated using SF....

In more general terms, do you have any specific plans for SF to support Ajax?

TIA,

Kari

Logged in User Problem

Sachin Saxena — Tue, 18 Dec 2007 03:03:58 GMT

Hi,

I am new in StrataFrame. I have problem to access the user information from web application.

I created a new user from the RoleBasedSecurity editor and trying to validate by custom login form in .aspx page.

I done the following setting in Global.asax:

DataLayer.DataSources.Add(new SqlDataSourceItem("", "server=ssaxena;integrated security=SSPI;database=StrataFrame"));

MicroFour.StrataFrame.Security.SecurityBasics.IsWebEnvironment = true;

cmdOk_Click:

MicroFour.StrataFrame.Security.BusinessObjects.SFSUsersBO sfUsers = null;

MicroFour.StrataFrame.Security.Login.LoginResult loResult = MicroFour.StrataFrame.Security.Login.AuthenticateUser("someshv", "jan@123", "", ref sfUsers); [ This userName and password is created in database by security editor ]

if (loResult.Equals(MicroFour.StrataFrame.Security.Login.LoginResult.Success))

Response.Write("Success");

if (loResult.Equals(MicroFour.StrataFrame.Security.Login.LoginResult.Failure))

Response.Write("Failure");

else

Response.Write("Nothing");

This returns me always failure. I am not getting any help. Can you tell me where I am wrong? or you can provide me any good documentation(besides StrataFrame doc) or sample application (besides Web Application Sample).

Is it worth to try?

Chan — Tue, 13 Nov 2007 11:57:09 GMT

Hi,
My company has couple of web applications which is focus on workflow type of app.
We are facing problem that, the code is very messy, take too long time to develop because programmer need to code almost everything (we are using MS Enterpise data access library). It also lack of feature like field permission and localization.

I would like to propose SF to my company. However, I never use SF as web development.

Anyone can share your experience? Should we migrate our web app to framework now? What are the impact?

Thank you

how to use the CheckBoxList

Fabian R Silva, - — Sun, 11 Nov 2007 20:55:52 GMT

I trying to test the web stuff, I'm new on it and don't sure how to use some .net controls, I see the web projects strataframe help and sample and follow all I can from it.

I trying to show a checkboxlist, but .net say that cannot convert from PopulationDataSourceSettings to WebPopulationDataSourceSettings. I trying to show a list of items from data loaded in a BO, and I like to select them with a checkbox (I not sure if I can handle when user checks one of them and reload the page with new results), or you recommend me use a datagridview, datalist, or repeater? thanks!

<SFWeb:CheckBoxList ID="chkPatentes" runat="server" PopulationType="BusinessObject" PopulationDataSourceSettings="Consultas.CommonBusiness.PatentesBO|FillByPrimaryKey;System.Int32|CodPatente,DescPatente,|[{0}] {1}|idPatente" Sorted="True">

ApplicationBasePage and Namespaces

PeterA — Thu, 18 Oct 2007 11:33:31 GMT

I had an interesting issue when I tried simplifying some code today and I'm not sure why this would happen.

I have my ApplicationBasePage that includes references to all my business objects. So far, so good. During the Page_Init event for each of my pages, I perform a few tasks related to the data layer (setting a Db2DataSourceItem attribute on the page) and initializing business object datasource keys (by calling a method in my Global.asax file called InitializeDataSourceKeys() that takes an ApplicationBasePage typed parameter).

I had a logic issue and needed to change the order (InitializeDataSourceKeys() needed to be called before I set my Db2DataSourceItem object). Thankfully, I only had 8 pages, but I thought it might be better to put the complete contents of the page event into a method in ApplicationBasePage so I wouldn't have to change it for every page in the future.

So I started moving it to a method in App_Data/ApplicationBasePage.cs called InitializeDataConnections(out ConnObj). Problem is, it wouldn't even compile the page.

I received an error that it couldn't locate the Db2 namespace in MicroFour.Strataframe.Data. It worked fine in my page, but not once I moved it to ApplicationBasePage.cs. I checked to make sure I had a reference to it for my Web Application Project -- and I did. I also checked to make sure I had a "using" statement at the top of ApplicationBasePage.cs -- and I did:

[quote]using MicroFour.Strataframe.Data;
using MicroFour.Strataframe.Data.Db2;[/quote]

I kept getting the error. I ended up just moving everything back to the Page_Init event and it works fine. But I'm wondering why it wouldn't work with the code placed in ApplicationBasePage.

Any ideas? Do I need to do something different to reference DataSourceItem objects in ApplicationBasePage?

Thanks!

Trapping Save() Errors

choyt — Tue, 18 Sep 2007 17:36:44 GMT

Hi Folks

I am currently doing something similar to the following on every save() I do.

Select Case Me.Save
Case MicroFour.StrataFrame.Data.SaveUndoResult.AbortedWithBrokenRules
Throw New BrokenRulesException(Me.BrokenRules)
Case MicroFour.StrataFrame.Data.SaveUndoResult.FailedWithExceptions
Throw New ApplicationException("The save failed.")
End Select

I trap for broken rules and bubble them up with one custom exception class, and throw exceptions for the other results. Because of this I wind up with an ugly Case statement for every save. Is there any reason not to move this logic to the ErrorSaving event of the business object's themselves to centralize this or is this just the best way to do it?

Thanks!

Populating a DropDownList with a Business Object

PeterA — Mon, 10 Sep 2007 11:34:55 GMT

I'm having some trouble getting a DropDownList to populate from a business object. I can get the page to load, but nothing shows in the object.

The business object is getting populated with the four records from the database to indicate a type, but these same four records aren't being transferred into the DropDownList.

1) PopulationType = "BusinessObject"
2) I've tried setting the "Method to Execute" option for PopulationDataSourceSettings to "Add()" and "Refresh()"
3) I've tried various combinations of settings for "PopulateOnPostBack" and "BindingDirection"
4) The same DropDownList is bound to a second business object where the unique key from the child business object is put into the foreign key field.

The binding piece doesn't seem to be a problem, but it keeps showing a blank drop down list. Is there something I'm missing? Something in my code to kick off populating the list?

Thanks for any help!

I have a business object mapped to a single table Table1. In FillDataTable the query retrieves few extra columns from Table2 by joining Table1 and Table2. How do I map columns from Table2 to a GridView in a webform?

How do we implement a 3-tier web architecture using Web services?

We have a web application which has a 3-tier architecture with the UI on a public server, the business logic methods exposed as web services on another server across the firewall, and a database on a third server.

Due to security reasons we are required to keep all business logic off of the public web server. We do this by using web services to connect to the middle tier.

How could we use StrataFrame to implement this architecture, with BO methods exposed as SOAP web methods to the UI layer?

BO interfere with each other

Hi,

I have a problem with a web from. If i open the web form in a single browser the everything works perfect. But if i open the same web form in two browser windows (each loading a different row of the BO-table) i get into a mess.

The problem is, that the row of the form that was loaded last is also used as the current row of the first form now. So whenever i postback the first form ( for example to get the form in edit mode) the wrong row of the business object is set for the page and changes are saved to the row of the second form.

I understand this is because the current row is stored with the BO in the ApplicationBasePage. What can i do to make the BO Session and "Browser-Window"- aware?

BO's in webforms question

So I understand that there is no dropping of BO's on webforms, you create the BO reference in your ApplicationBasePage and it available to the entire website. Check.

Does that mean I need to create many BO's if I need them populated differently? For instance I have a BO that contains codes used to fill all my applications dropdowns, I have a BO on each form that calls a fill specific for the proper contents of the BO based on a "codetype" field.

So the generic question is this, since BO's essentially don't get instantiated into individual objects on a webform where I can call different fill methods, is the answer to make many BO's specified to their task, or am I on the wrong path?

Combining Strataframe and Infragistics classes

Is it possible to combine the Strataframe classes, particularly the Business Objects, with the Infragistics classes in order to get the look and feel of these?

Thank you,

Alex

Webforms Tutorial?

Greetings Strata-Folks!

Is there a webforms tutorial beyond the web sample that is included with the framework?

Thanks!

Sorting Listview

Mark Dowlearn — Thu, 26 Jul 2007 07:18:52 GMT

My experience thus far indicates that in a when a field is processed within a listview so that it includes a format string or uses the "PopulatedThroughEvent" method, the sorting does not accurately reflect the base value.

For example, if I'm sorting on a name column and want to add a format string (<a href= "... ) to make the name be a link when viewed on the web page, the sorting gets messed up and does not display the list properly.

Has anyone else experienced this also? If it's by design, then I request that the design be changed <smile>.

At least in the case of creating a hyperlink, I would have expected that the sorting would still be on the base value of the field (or whatever the displayed text of the link is if the two are not the same), but this does not appear to be the case.
