Thank you for your reply.
First, we would like to apologize. The same problem exists in previous versions of RadGrid Control too.
We assumed that REBINDING the data-source of a RadGrid, will change the information in all its tables: master AND details. We think that such functionality is very trivial and expected, as the idea is to change the whole data of the grid!
Meanwhile, we found a workaround implement the DYNAMIC functionality that would meet our project’s requirements. We programmatically remove the old details table and add a new one:
Code (On the treeView_node_cilck Event):
GridTableView = RadGrid1.MasterTableView.DetailTables(0)
Here is a video demonstrating the workaround:
We wrote a feature request
that rebinding the RadGrid will AUTOMATICALLY rebind all tables and all data!
