Microsoft release a service pack for Silverligth 4.0 which now allows the Silverlight DataGrid to display a new row at the bottom of the grid.
Important to me is:
Issue 2 – This update enables new Add Row functionality in the Silverlight DataGrid control.
,Issue 7 – Fixed various memory leaks including:
- Memory leaks that occur when mouse capture is used. For example, memory leaks that occur when you use CaptureMouse() in drag-and-drop scenarios. For more information, see the following Microsoft Silverlight forums discussion.
- Memory leaks that occur when UserControl cannot be garbage-collected because it contains inline data template. For more information, see the following Microsoft Silverlight forums discussion.
The have also fixed 5 other issues for more information goto KB2164913.
08-Sep-2010 – Update:
For the New line to work you have to implement the System.ComponentModel.ICollectionView interface.
