Hi there

I have a Hierarchical grid setup and it is working 100%, but now I need to apply filtering on the MasterTable. So I have changed my databinding to use the NeedDataSource event.

The problem is I need to reload the grid based on two external filters (drop downs), so to reload the dataset based on this I set the EnableViewState="false" on the MasterTable, this works fine. Now the problem is that when I do a post back in a child element of the MasterTable it resets as well and I "lose" the focus of the child item I was working on.

Is there a way I can rebind the datasource programmatically when the OnSelectedIndexChanged fires on the drop downs with EnableViewState on the MasterTable Enabled?

Hello,

 You do not need to disable the viewstate of the MasterTableView. You can simply force the control to be databound earlier by calling the Rebind() method of the grid - this will execute the NeedDataSource event and the control will bind.
