Sounds good.  I will send you an example tomorrow.  In fact, I will post the sample on the forum so other users can see how to do this as well.

FYI, Rob,



The version that supports compound primary keys also implements IBindingListView and ITypedList on the BusinessLayer class (all business objects), so you can now assign a business object directly as the data source for a grid. This also solves the problem of needing to re-assign the data source each time you fill the business object (because the internal data table reference changed).



Additionally, when you Add and Delete records, it uses the appropriate methods on the business object to ensure that the proper hook events are fired (such as SetDefaultValues).

Hi Ben,

Very cool, now that you've implemented the I-faces I see the BO in the drop-down list for DataSources.

However, I attempted to assign a simple BO to a SF ComboBox DataSource and Assign my text value to DisplayValue, I get the following error at runtime:

"Items collection cannot be modified when the DataSource property is set."

ApplicationException
 An error occurred while creating the main form
TargetInvocationException
 Exception has been thrown by the target of an invocation.
ArgumentException
 Items collection cannot be modified when the DataSource property is set.

Rob,



The reason you're getting that exception is that .NET will not allow you to manually add items to a combo box when you set the DataSource property to an object. So, make sure you don't have items in the combo box. Also, make sure the PopulationType property is set to Manual.



However, the SF ComboBox was designed to be populated using a business object through the PopulationDataSourceSettings property, not by setting a business object as the data source directly. You might give it a try. There's a tutorial topic on ListControl Population under Getting Started -> Tutorials -> Creating a WinForms App [VB] -> List Control Population.

Hi Guys, I'm very excited about you guys creating a DevExpress wrapper so that their Grid product can be used seamlessly with StrataFrame. How will you guys be notifying us when the wrapper is ready? The forums or a mass email to registered users?



P.S. I'm just curious... What made you choose to create a DevExpress wrapper first out of all the other grid products?



Thanks

Mike,



We'll be notifying people through a mass email on the forum. As for choosing DevExpress first over other grid products, we had several users specify that they wanted to use DevExpress controls (no one really mentioned anything else). As for the grid itself, we aren't going to subclass it other than to create a "list" that works similar to our current ListView (in details display mode). You can already use a DevExpress grid with a business object as the data source, so we aren't going to create a custom wrapper for the GridControl or GridView.

An Infragistics wrapper is not a function of development -- it is a legal issue.  We are currently waiting on a ruling from Infragistics' legal department.  Their current stance is we can't distribute a wrapper without violating their license.  I know it seems crazy all it would do is help them sell more copies.

 

Nevertheless, they will not respond to our requests.  If you want a wrapper you need to contact their sales department and nudge them along.

Last week I sent an e-mail off to Infragistics Sales asking them if I should switch to Dev Express controls if I wanted something that would be easy to use with your Framework. I received an email back this morning saying that they would contact you. Hopefully both companies will work things out and we’ll get an Infragistics wrapper.

Yes, as a matter of fact, they contacted us just a few minutes ago.  We'll let you know the results of our correspondance with them

Hi,

What is the situation with the DevExpress wrapper?
