My Requirement: What I need is, Based on the value in the text box the 3 gridviews should get bound. and it should display Once after another as shown in the sample image below
my problem is only the 1st grid is binding but not the child grids.as shown below.
Here is my aspx code:
<asp:UpdatePanel ID="UPDestinationGrid" runat="server" UpdateMode="Conditional">
