我正在尝试开发每次单击图像时打开的页面不止弹出窗口。当我单击此图像时，会出现一个弹出菜单，其中 gridview 根据页面中的某些文本框填充了数据。问题是，当我第一次写页面时它起作用了，但后来却没有。

后面的代码是

ImageButton lb = sender as ImageButton;
    string shipto = ddlShipto.SelectedValue.ToString();
    TMWWS.BusinessLogic.ProfileII objPlants = new                 TMWWS.BusinessLogic.ProfileII(shipto);
    DataTable dt = objPlants.getPlantsPerShipto();
    gvPlant.DataSource = dt;
    gvPlant.DataBind();
    this.upPlant.Update();
    //pnlPlant.Visible = true;
    pnlPlant_ModalPopupExtender.Show();



  <asp:ScriptManager ID="ScriptManager1" runat="server">

您可以尝试改用 Popup 扩展程序。这是一件棘手的事情，我遇到了同样的问题，我正在尝试使用弹出扩展器。这是一些代码片段。

<asp:LinkButton ID="LnkOrder" runat="server" BehaviorID="pop" CssClass="PopupMenu" CommandName="LnkOrder">Order</asp:LinkButton>
                     <asp:PopupControlExtender ID="LnkOrder_PopupControlExtender" 
                   runat="server" DynamicServicePath="" Enabled="True" ExtenderControlID="" 
                   PopupControlID="PopupMove" TargetControlID="LnkOrder">
               </asp:PopupControlExtender>

另外我 fyou 需要隐藏弹出窗口尝试使用这个 javascript。不要忘记更改 BehaviorID。这是javascript

$find('pop').hide();
