Keep Expanded NestedViewTemplate on Rebind of Parent RadGrid

[Scott Marx]

I have a RadGrid with a NestedViewTemplate that has another RadGrid in a RadPageView, when I update the RadGrid in the RadPageView I need to rebind the Parent Grid and keep the Parent RadGrid item expanded and RadPageView displayed.

Any suggestions?

Hello Scott,
Try the following approach to achieve your scenario.
C#:

int flag = 0,index;
   protected void RadGrid2_UpdateCommand(object sender, Telerik.Web.UI.GridCommandEventArgs e)
   {
       RadGrid grid = (RadGrid)sender;
       GridNestedViewItem item = (GridNestedViewItem)grid.NamingContainer;
       GridDataItem parentItem = (GridDataItem)item.ParentItem;
       flag = 1;
       index = parentItem.ItemIndex;
   }
   protected void RadGrid1_PreRender(object sender, EventArgs e)
   {
       if (flag == 1)
       {
           GridDataItem item = (GridDataItem)RadGrid1.Items[index];
           item.Expanded = true;
           flag = 0;
       }
   }

Thanks,
Shinu.
