Hi All,
I have a two level hiearchary RadGrid and in the MastertableView there is a column which is a sum of a column in the DetailsTable. When I update a row in the DetailsTable how can I force the parent MasterTableView row to update as well to reflect the new sum?
Thanks

Hello chase,
Here is what you need to add. In the UpdateCommand event handler, you can get a reference to the updated item's parent item and update a control in it. The following example assumes we have created a template column in the MasterTableView with a label control inside that can be updated when child items are edited:
The above code checks if the currently updated item belongs to a detail table, and if true, gets the item's parent item and updates a control inside its template column.
