successful in doing this but I need the embedded grid to fire its
ItemDataBound event so I can handle it. The event does not seem to fire for
some reason. The code is below.
Look towards the end of the CustomerDataGrid_OnItemDataBound(object sender,
DataGridItemEventArgs e) method. This is where I register the event and
place the programmatically created grid into the main grid. The registered
event does not cause the OrdersDataGrid_ItemDataBound to run.
Appreciate anyones help.
Thanks,
Girish
