BO's in webforms question

Keith Chisarik — Tue, 14 Nov 2006 11:00:00 GMT

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?

How to encode result returned from SQL

Greg McGuffey — Mon, 28 Sep 2009 16:55:08 GMT

I have a need to encode the results of a SQL query for use with the web listview. I'm querying a database I have no control over to get a list of contracts. The contract ID is a varchar field that could include spaces. I want to then show this ID as a link and use the ID within that link. Of course the spaces are wreaking havoc. I could write a function in SQL Server to do a basic encode, but I'm wondering if there is a way to do this via either the listview or via a ASP.NET function call?

Example:
Data (ID) Desired <a> Link
----------- --------------------------
MS3 DM008 <a href="ContractDetails.aspx?key=MS3%20DM008">MS3 DM008</a>

Creating web pages menu options from XML file

Doron Farber — Sat, 22 Aug 2009 15:39:29 GMT

Hi Trent,

I have the below sql which stores the menu options names. So this way I can populate into the web pages the options names etc... If you look at this web site: [url]http://www.Intelius.com you[/url] will see People Search as the main option and then when you click that you will see all tabs. The name of the tabs are coming from the dbo.SearchCategories.SearchCategory and for the main Search option it is coming from the dbo.SearchOptions.SearchOption. It is generated as an XML file. Based on that XML the menu options and tabs are created on the fly. It is like a small Content Management. All Contents Management forms are created as smart clients app.

1)
How would you link that from the XML file into the Index.ASPX? I am trying to find the most productive way for this process.
2)
Do you handle your web site this way?

[codesnippet]
SELECT
dbo.ServiceOptions.ServiceOption,
dbo.ServiceOptions.DisplayOptionOrder,
dbo.SearchOptions.SearchOption ,
dbo.SearchOptions.DisplayOptionOrder,
dbo.SearchCategories.SearchCategory,
dbo.SearchCategories.DisplayOptionOrder,
dbo.SearchCategories.SearchCategories_PK,
dbo.SearchCategories.Comment,
dbo.SearchCategories.Tip
FROM
dbo.ServiceOptions
INNER JOIN dbo.SearchOptions
ON dbo.ServiceOptions.ServiceOptions_PK=dbo.SearchOptions.ServiceOptions_FK
INNER JOIN dbo.SearchCategories
ON dbo.SearchOptions.SearchOptions_PK = dbo.SearchCategories.SearchOptions_FK
WHERE dbo.ServiceOptions.DisableOption = 0 AND dbo.SearchOptions.DisableOption = 0 AND dbo.SearchCategories.DisableOption = 0
ORDER BY dbo.ServiceOptions.DisplayOptionOrder,dbo.SearchOptions.DisplayOptionOrder,dbo.SearchCategories.DisplayOptionOrder
FOR XML AUTO , ROOT('Menu_Options')
[/codesnippet]

IListServer implementation for DevExpress Server Mode

Andria Jensen — Mon, 13 Jul 2009 18:29:41 GMT

Do you guys implement IListServer for the BOs and if not, can you point me in the right direction of how to implement this myself? We are are generating a few really large datasets and it is taking a while to render them without having this implemented. Thanks!

XML Problem while using Stored Procedure

Doron Farber — Tue, 16 Jun 2009 14:33:31 GMT

Hi Trent,

I am actually running an sql statement and getting the XML via the ms sql 2008. Testing the XML within the ms sql 2008, it is just fine. When running the below code the XML string is broken. I am using the BO which is the parent of all the tables that are included within the sql statement? When I copy this line Me.ExecuteScalar(cmd) into the Watch window and look into the XML string I am getting an error.

How can I resolve this problem?

Public Function GetXMLMenuOptions() As String
Dim cmd As New SqlCommand()
cmd.CommandType = CommandType.StoredProcedure
cmd.CommandText = "XML_MenuOptions"

Return Me.ExecuteScalar(cmd)

End Function

Thanks,

Doron

What's the best a way to convert ms sql 2008 data to XML files?

Doron Farber — Fri, 12 Jun 2009 09:40:42 GMT

Hi Trent,

Say I have several tables related to each other and I want to create the hierarchy of the data such as parent child within the XML.

These are small tables where I store the data of menu options and sub options etc...
Then I use the XML file for the web site to display all options etc... I need to select only certain fields that hold the data for the menus. I have some other fields that are not needed for the XML.

I appreciate any feedback.

Thanks,

Doron

Shared BO by Static property and ServerDataChanged

ChanKK — Sat, 16 May 2009 09:48:08 GMT

Hi,
I would like to use static property to stored some shared BO instance and data (as suggested by SF). Beside, I also would like to implement "auto requery" if any underlying data changed at server.

Anyway to make sure "auto requery" doesn't crash the web app? e.g. while ServerDataChanged event fired, there might be record populating taking place for ASPX. It I try to re-fill at that time, it might crash the system. I was thinking to use lock() statement to lock another static object for this purpose. But where should I do so?

Please advice. Thank you

Sample web site

Peter Jones — Wed, 06 May 2009 20:06:28 GMT

Hi,

It looks as though we are getting involved in a new ASP project and so we are about to get onto a steep learning curve with ASP and WebForms.

I presume that all the SF knowledge we have with the SF DAL and Business Layer will just port over - I couldn't see any caveats in the SF help saying 'this doesn't work in ASP'.

What I was hoping to scrounge is a sample ASP web site built using SF to give us a feel what such a beast looks like.

Can anyone help?

Cheers, Peter

Memory leak SF BO with DevExpress ASPxDataGridView

ChanKK — Wed, 11 Mar 2009 09:18:58 GMT

Hi,
I am facing memory leak problem when using SF BusinessObject and DevExpress ASPxDataGridView.
I have simple test project, which only has one BO, bind to ASPxDataGridView. It does nothing complicated, just load all records in Page_Load if not IsPostBack.

I found that, the memory usage would become double when I just "refresh" the page. I also used dotTrace profiler and found that # of BO instances keep increasing. I suspect it is the same issue with the post http://forum.strataframe.net/Topic20903-8-1.aspx.

I have prepared sample project and the dotTrace memory profiler files for your reference. MemoryLeak1.dtm is first load memory snapshot and MemoryLeak2.dtm is 2nd snapshot after refresh.

As the file size > 30MB, please download it from http://www.visualsolutions.com.my/blog/chankk/WebApplication6.zip

Hope you could get back to me as soon as possible! It is very urgent!

Thank you

How to dispose BO stored at field?

ChanKK — Thu, 30 Apr 2009 07:20:45 GMT

Hi,
I have initialized a BO to MasterPage's private field.

[codesnippet]private MyBO _myBO = new MyBO();[/codesnippet]

How could I dispose it? I tried to override MasterPage.Dispose() and call BO.Dispose(). However, it is not been released. I check using ANT profiler, it still show the BO is still at memory.

Any ideas?

BrokenRules localization

Jiri Brazda — Mon, 20 Apr 2009 08:56:53 GMT

Hi,

I need to set broken rules and corresponding texts to a particular language (e.g. Czech). In windows application in works fine since Czech texts are built into StrataFrame core. With the web application broken rules texts are still in English even when the localization is set to 1029 and all texts read from XML are in Czech version.

I set localization in Application_Start method in Global.asax file with the following code:

MicroFour.StrataFrame.UI.Localization.MessageKeyType = MicroFour.StrataFrame.Messaging.MessageKeyDataType.XML;

MicroFour.StrataFrame.UI.Localization.MessageXmlPath = ConfigurationManager.AppSettings["LocalizationFilesPath"];

MicroFour.StrataFrame.UI.Localization.MessageLocaleID = 1029;

Am I doing something wrong?

Thank You

Business Object and StrataFrame controls in User Control

Jiri Brazda — Tue, 07 Apr 2009 13:20:06 GMT

I would like to use user controls in my web application. However I'm not able to bind strataframe components like textbox etc. on my user control to business object. In one of previous topics about this problem it was mentioned the following:

Web controls are a little different than winforms controls, but you can still use them. You can call whatever strataframe controls you need to inside of your web control, but you will have to take the binding for them into account in the render method of your web control. In winforms it handles the equivelant functions for you, but in web you have to do it yourself.

Outside of that, you're free to use them as you wish

Could anybody put here a piece of code or a very simple sample that would demonstrate how to do it?

Thank You.

Implementing Security in a Web App

Milton Abe — Tue, 10 Mar 2009 10:20:04 GMT

Hello! I've been searching for an example or sample where it implements a Logon Web Form but I haven't found any. Also I'd like to to implement a kind of expiration page thing, maybe with Sessions objects or stuff like that. Does StrataFrame has something to control this? A Logon form and Session control? If so, I guess my app should have a table to control this, right?

Thanks in advance,

Creating a web site project in a separate Solution?

Doron Farber — Wed, 04 Mar 2009 17:05:48 GMT

Hi Trent,

I need to create a web site which I created for it many forms for administration purpose using win forms . The BOs are also in separate folder as well. I tried to follow the same organization as appears in the sample app.

My question is should I create a separate Solution or create another project under the same solution? I am not sure if the web will need any BO created for the admin. The Admin is using a different database as well.

Thanks,

Doron

Adding new item in a Web ComboBox

The code generated should be something like this:

All the values but the first one should come from the database. The first one I'd like to add manually..

Thanks in advance,

Need to create a BO for multiple tables

Doron Farber — Mon, 19 Jan 2009 19:53:57 GMT

Hi There,

1)
I need to search on multiple tables and the data from 20 TO 70GB

Since the data is pretty big I found out the best thing is to use a dynamic sql statement where I define on the fly the parameters to be used. I can NOT use a view with constant number of parameters since it will be too great of an impact on the execution plan.

I am trying to see how can I use a BO under this condition. For instant if the first sql gets 0 records, then in the same SP I will pursue with another SQL statement to grab from different set of tables.

How do you assign a BO to this kind of process.

2)
I need to use some audit trail. Like if the user enters FirstName, LastName and State for search purpose. I need to enter that as a record for an audit trail and then the results of the search as well. It could be up 100 records. Obviously that could be as a simple Insert.

How is the audit trail is coming along in the SF? Is that something that I can use?

Regards,

Doron

Hi,

I created a web project in vs. 2005. Later moved to vs. 2008 and it converted it. Also changed it from .net 2.0 to 3.5.

The Solution contains the main webforms project, a bol base project, and a bol project. The solution compiles fine and I can publish and run it to my XP testing server.

But when I publish it to the production windows 2003 server then I get the error below. Any suggestions on what gives?

Custom logic of InitializeBusinessObject

Chan — Wed, 04 Feb 2009 19:44:26 GMT

Hi,
Currently, SF's webform would use page property name (BusinessLayer derived type) as key to store BO instance to session. I would like to customize this because we faced issues that, since BOs are "shared" among all forms (same property name), it causes developers need to be very careful on any settings done in other form such as BO.filter and etc. It also complicated the troubleshooting process.

How could I customize it? I would like to use Form.UniqueID + Form.BOPropertyName as key. I checked the source code and found that it is almost impossible. Even though I am able to prevent BasePage.Page_PreLoad to be fired and override with my own logic using Reflection, but it still not bullet prooof. As I see some other code call BasePage.GetBusinessObject() directly which I couldn't hijack it.

Please advice. Urgent!
Thank you

When run the method save without breakpoints in code he saves the Registered in Database but the buttons Save and Undo continue active, being necessary clicking 2x back for state of navigated. When run with debug and some breakpoints he saves correctly. What may occurring? This so happens in some forms my not all.

BO IsDirty set to false after failed save

Govinda Berrio — Wed, 03 Dec 2008 09:23:33 GMT

First of all I'd like to say that this is most likely a problem with the way the page is contructed by me. I know that because I created a small test web app that does show what I'm about to explain.

I coded this page doing testing here and there. One day I was on a record that was saved before I had set the require fields validation on the BO. I saved the record, saw the validation error message for one of the required fields being blank, and for some reason I just hit Save again. To my surprise, the form saved successfully. Or rather, the BO.Save() method return "Success". After some digging I found that the BO was losing track of the fact that the record was dirty. It was registering as dirty for the first save (IsDirty == true) but on the second save, IsDirty was false. So I think what's happening is that Strataframe isn't attempting to check rules or save. And I don't do any reloading of the record in between. The BO is part of the BasePage so it's getting stored in the Session.

I tried manually setting the record to dirty with BO.CurrentRow.SetModified() but I get an error saying that the row state has to be Unchanged in order to use SetModified or SetAdded. I tried updating a timestamp field on the BO (ex. Customer.Created = DateTime.Now) and the record was still not registering as dirty.

I'm just going to validate the required fields manually and move on, I've spent too much time on this already.

So I know there's something I'm doing wrong because it works in a simple implementation. But I wanted to get it out there and see if anyone else has had a similar experience and if they found a reason and a solution.

Thanks
Govinda

Same form property name but difference BO type

Chan — Sun, 21 Dec 2008 20:54:59 GMT

Hi,
Just would like top share my experience which cause error in my application and spent me quite long time to troubleshoot it.

Make sure we are not using same property name in form to declare difference type of BO (even in difference webpage) because it would cause error "Unable to convert BOType1 to BOType2".

Scenario:
1. Declared property Leave for namespaceA.LeavesBO in FormA.
2. Declared property Leave for namespaceB.LeavesBO in FormB.
3. Run formA and then FormB. The error mentioned would occured.

It is because SF's webpage would use property name as key to store BO instance at session. When run FormB as scenario above, SF found "Leave" from session and use it directly. However, it is not actually the correct BO instance needed.

I am not sure it is by design or bug. However, would like to share with all.

Thank you
