modal popup extender:
<asp:TemplateField HeaderText="Reject">
                <asp:LinkButton ID="lnkReject" runat="server" onclick="lnkReject_Click">Reject</asp:LinkButton>
                <cc1:ModalPopupExtender ID="ModalPopupExtender1"  CancelControlID="btnCancel"  runat="server" TargetControlID="lnkReject"

I think this is because you have created the click event of the linkbutton and assing it as the TargetPopupID of modalpopup.

You have two options to solve, remove the linkButton click OR add the ModalPopupExtender.Show(); statement at the end of linkButton Click event
