Hello Pardha,

In ItemCommand event check whether the DetailTable is refreshing and store the index of parent grid item. Then in Prerender event expand the corresponding Grid Item.

ASPX:

<DetailTables>
       <telerik:GridTableView Name="Detail2" CommandItemDisplay="Top" >
          . . . . . . . . . . . . . . . .  . . . . .
</DetailTables>

C#:

int parentitemIndex = -1;
  protected void RadGrid1_ItemCommand(object source, GridCommandEventArgs e)
   {
      if ((e.CommandName == "RebindGrid") && (e.Item.OwnerTableView.Name == "Detail2"))
       {
           GridDataItem item = (GridDataItem)e.Item.OwnerTableView.ParentItem;
           parentitemIndex = item.ItemIndex;
       }
    }
  protected void RadGrid1_PreRender(object sender, EventArgs e)
   {
       if (parentitemIndex > -1)
       {
           GridDataItem item = (GridDataItem)RadGrid1.Items[parentitemIndex];
           item.Expanded = true;
       }
   }

Thanks,
Princy.
