c#之在 gridview 链接按钮上打开 ajax 模式弹出窗口

我试图在 GridView LinkBut​​ton 上打开一个 ModalPopup，但是当我将 LinkBut​​ton ID 提供给弹出窗口的 targetcontrolid 时，它不接受。 请帮助我。

<asp:GridView ID="grdView" runat="server" AutoGenerateColumns="False" CellPadding="0" 
            ForeColor="#333333" GridLines="None" onrowdatabound="grdView_RowDataBound"> 
    <Columns> 
        <asp:TemplateField HeaderText="Dr. Photo"> 
            <ItemTemplate> 
                <asp:Image ID="Image1" runat="server" Style="height: 80px; width: 100px;" ImageUrl='<%#  String.Format("~/Upload/Docters/" + Eval("ImgName")) %>' /> 
            </ItemTemplate> 
        </asp:TemplateField> 
        <asp:BoundField DataField="Name" HeaderText="Name" ItemStyle-Width="150px" > 
        <ItemStyle Width="150px"></ItemStyle> 
        </asp:BoundField> 
 
        <asp:BoundField DataField="Qualification" HeaderText="Qualification" 
            ItemStyle-Width="50px" > 
        <ItemStyle Width="50px"></ItemStyle> 
        </asp:BoundField> 
        <asp:TemplateField HeaderText="Click to Contact"> 
        <ItemTemplate> 
        <asp:LinkButton ID="popup" runat="server" Text="Click to Contact"></asp:LinkButton> 
        </ItemTemplate> 
        </asp:TemplateField> 
    </Columns> 
</asp:GridView> 
 
<ajaxToolKit:ModalPopupExtender id="ModalPopupExtender1" runat="server" 
    cancelcontrolid="btncancel" okcontrolid="btnSend" 
    targetcontrolid="Button1" popupcontrolid="Panel1" 
    popupdraghandlecontrolid="PopupHeader" drag="true" backgroundcssclass="ModalPopupBG"> 
</ajaxToolKit:ModalPopupExtender
