                             <ItemTemplate>
                                 <asp:Label ID="lbl1" runat="server" Text='<%# Bind("grvtype_desc") %>'></asp:Label>

                         </asp:TemplateField>
                         <asp:TemplateField HeaderText="Status">
                             <ItemTemplate>

                         </asp:TemplateField>
                     </Columns>
                 </asp:GridView>
             </div>
         </div>
     </div>
 </asp:Panel>

  <asp:ModalPopupExtender ID="modalPopup1" runat="server" PopupControlID="pnlGrievanceList"

     TargetControlID="lnkbtnStdGrvList" BackgroundCssClass="modalBackground" OkControlID="Button1">
 </asp:ModalPopupExtender>

在页面加载中我填充grvLst，当我点击LinkBut​​ton时lnkbtnStdGrvList'然后在lnkbtnStdGrvList_click事件代码是

modalPopup1.Show（）;

在母版页上我有脚本管理器

但是modalPop没有显示为什么？

In Page load i Fill grvLst and when I click on LinkButton 'lnkbtnStdGrvList' then on lnkbtnStdGrvList_click event code is
modalPopup1.Show();
On master page i have script manager
But modalPop is not showing Why?
