Hi Juraj

Thanks for the reply, I used following code for the update panel

<asp:UpdatePanel ID="upShowItems" runat="server">
<ContentTemplate>

My code goes here.....

</ContentTemplate>
</asp:UpdatePanel>

When I select a value from list box and click the show link, I wants to update the contents in the panel. But unfortunately it is not loaded the contents.

If I missing anything?
