The next segment of the CSLA 4 MVVM video series is now available for download.
The pre-release price has changed as well, as I'm almost done with the series. I'm still on track for being done by the end of July, as there's just one more video to go.
This latest video segment illustrates how to create an editable root list of child objects, along with a corresponding viewmodel object. That viewmodel is used to create a view using the Silverlight 4 DataGrid control.
The end result is, with very little effort, to have a fully functional in-place editing experience, complete with validation rules displayed.
As a bonus, the demo has also been updated to use an in-memory mock database, and the video briefly walks through the construction of that mock database and shows how the DataPortal_XYZ methods were updated to take advantage of this concept.
