    • Re: WPF DataGrid that works properly with databinding and CSLA

      I thought I would share my findings with the group in case someone else has a similar issue. We were trying to update an older WPF application that used CSLADataProvider. The app needed a data grid for quick entry. We tried several data grids but they all failed to bind a modified row to the newly returned...

    • DatagridView (Winforms) behavior when upgrading to 4.0

      Hi, I upgrade a .NET 2.0 and CSLA 3.8 Projekt to .NET 4.0 and CSLA 4. I've got a BO with a child-collection bound to a bindingsource. Via a button new elements could be added to the child collection. OK so far and unchanged. But other than before, the Datagrid which is bound to the child-BS doesn't...

    • Saving business object in Mono

      I have a simple editable child list bound to a DataGridView control. After making changes to the grid, I use ApplyEdit() and Save methods to save the root business object (thereby saving my child list). This works in Windows .NET perfectly fine. On Mono, however, saving the root object provides the following...

    • Re: BusinessListBase and MarkAsChild

      You can certainly try. When I looked at the problem originally I did take a quick look at the events on the datagrid control and didn't see a way to override the default behavior. Most datagrid controls do have a way to override this behavior though, so perhaps I just missed it...

    • Minor bug in LinqObservableCollection

      We are using the CSLA LinqObservableCollection with WPF 4 in CSLA 4.0.1. This is a very useful class. However, two of our team members, Brent Edwards and Marty Robertson, have discovered that there is a minor bug. Specifically, in the IndexOf(object value) the released code reads: return _baseCollection...

    • Using Business Rules with a DataGrid

      I have a question regarding the use of the business rules subsystem with a DataGrid control. I'm using Silverlight 4, C# 4, and CSLA 4. Basically, I have an EditableChildList whose objects I'm displaying in my DataGrid. I have also added some business rules to the class as outlined in Rocky's...

    • Re: BusinessListBase and MarkAsChild

      I assume "Get Microsoft to fix the *(#$@ WPF DataGrid" isn't an option... From my perspective, I don't see much other choice. As crappy as the WPF DataGrid is, not being able to use CSLA collections with it is a problem. While I understand the issue with hiding a potential programming...

    • BusinessListBase and MarkAsChild

      In CSLA 4 an exception is thrown when you attempt to add an object to a BLB and that object isn't a child. That's good, in that it enforces an important rule. However, it causes issues with the WPF datagrid control, which has no hook where you can create a new object when the user hits the last...

    • help with SelectObjectArgs and Telerik RadGrid

      Hi have a issue with my Telerik RadGrid. It has a column of checkboxes that do not maintain values when the user goes to enter a new item. I have come to the conclusion that the selectobjectargs pulls the records from the datasource each time the user goes to add a new item. The issue is with Telerik...

    • WPF datagrid New item placeholder for empty collection

      I have a CSLA-like class that I bind to a WPF toolkit DataGrid. I do not normally allow editing in a grid, but I have a new application where that makes sense. When the collection that I bind to is empty, the new item placeholder does not appear. When the collection has rows, it does. I have read about...

    • Re: How to sort a ERLB ?

      When binding your BindingSource, you should be able to use bindingSource1.DataSource = new SortedBindingList<MyBO>( myErlb ); Is that not working?

    • How to sort a ERLB ?

      Hi, To manage some data, I use a datagridview (WinForms) bound to a ERLB (data saved once the row changes). Everything is OK. But now, I want to be able to sort rows of the datagridview with a mouse click on the column header. With a SortedBindingList, there is no problem for that but with a ERLB it...

    • Re: Silverlight Object is still being edited and cannot be saved

      Every BeginEdit() call needs to have a matching ApplyEdit() call on that specific object . When using in-place editing in a datagrid control, the datagrid is responsible for using the IEditableObject interface to call begin/end/cancel edit on each row as the user enters and leaves that row. I know there...

    • Re: silverlight csla:ValidatedDataGridCheckBoxColumn

      The read-only issue sounds like a bug, I've filed it in the bug list. The other issue may be due to the way data binding works, but it could also be a bug. Either way, I added a bug entry for that as well.
