Question

因为我手动想要显示模态弹出窗口（这可能是因为弹出窗口内的控件必须根据按下的按钮或行进行初始化）。谁能帮我？按钮永远不会进入这个EditBtn_Click方法，它只是显示我的面板。

代码：

      protected void EditBtn_Click(object sender, EventArgs e)
    {
        LinkButton btn = (LinkButton)sender;
        GridViewRow row = (GridViewRow)btn.NamingContainer;
        int i = Convert.ToInt32(row.RowIndex);

        string uid = (string)ManageStaffGrid.Rows[i].Cells[1].Text;

        //bind panel


        AjaxControlToolkit.ModalPopupExtender mpe = (AjaxControlToolkit.ModalPopupExtender)row.FindControl("EditBtn_ModalPopupExtender");
        mpe.Show(); //show the modal popup extender

    }
