DataGrid Refresh Problem

Apr 10, 2009 at 10:56 AM
In the DataGrid we have a Master detail scenario by using the Main Table as the itemsSource of the Main Grid and the Relationship as the ItemSource of the ChildGrid. In the Main Grid we have a column in which a Button can be clicked to Duplicate the Main Record and All its children. Although the duplicated Main Record in the Main Grid shows up correctly, the Duplicated Children do not show up (even though they habeen created in the underlying DataTable) unless you close the application and re-run it to see the Duplicated Child Records .
