一旦单击按钮，执行操作，我想在后面的代码中显示模式弹出窗口，接下来就是显示模式弹出窗口。我有 modalpopupextender, popup, button 设置为display:none，因此模态弹出窗口不会引发错误。

我在 gridview 中有 imagebutton ，我从中触发后面代码中的动作，一旦执行动作，我希望显示模态弹出窗口。

这就是我所拥有的。标记：

                        </tr>                     
                    </table>

                <tr>

<div style="padding-left:25px; padding-right:25px; padding-top:5px; padding-bottom:5px;">Are you sure you want to Archive this posting?<br></div>
</div>
                    </td>
                </tr>
                          <tr>
    <td style="width:100px; margin-top:5px; padding-left:50px;">
        <asp:ImageButton ID="btnUpdate" ImageUrl="~/Images/btnarchive.jpg" OnClick="btnUpdate_Click" runat="server" />
        <asp:ImageButton ID="btnCancel" ImageUrl="~/Images/cancel.jpg" runat="server" />
        <asp:HiddenField ID="hfPostingID" runat="server" />
</td>
</tr>

            </table>
        </div>
    </asp:Panel>

CancelControlID="btnCancel" BackgroundCssClass="modalBackground">
</ajaxToolkit:ModalPopupExtender>       
    <!-- LOGIN PANEL -->
</asp:Content>

然后在后面的代码中我有这个：

protected void imgButton1_Click(object sender, ImageClickEventArgs e)
    {
        ImageButton btndetails = sender as ImageButton;
        GridViewRow gvrow = (GridViewRow)btndetails.NamingContainer;
        string postingID = btndetails.Attributes["RowIndex"];
        if (postingID != string.Empty)
        {
            hfPostingID.Value = postingID;
        }
        ModalPopupExtender1.Show();

      //  this.ModalPopupExtender1.Show();

    }

如您所见，我尝试了 this.ModalPopupExtender1 和 ModalPopupExtender 但我得到了相同的响应。

不要在我面前有 Visual Studio；但以下内容希望能帮助您朝着正确的方向前进！

替换 ImageButton 标签如下：

<asp:ImageButton ID="imgButton1" commandName="Click" commandArgument='<%# Eval("PostingID") %>' runat="server" ImageUrl="/images/a.png" />

在后面的代码中，使用 gridview 的 RowCommand 事件代替图像按钮的单击事件：

    private sub GridView1_RowCommand(.......) handles ....

    dim xvar=e.commandArgument
    if e.commandName="Click" then
    ...use the **xvar**  to perform custom task before you show the modal popup...
    find the modalPopupControlExtender using FindControl and then use the .SHOW() property
    ...
    ...
    end if

end sub
