I have exactly the same requirement as Detlef needed in the following thread
http://www.syncfusion.com/support/forums/grid-windows/76128/Is-there-a-DefaultValuesNeeded-, however the solution zip file at the end of the thread is no longer available. Basically, I need to set some values in the data row that is being added. The columns I need to set are NOT displayed in the grid control. This problem would be sooo much simpler if there were a "RowSaving" event rather than a "RowSaved".
