当modalpopupextender调用updatepanel时，我无法更新更新面板。它是一个小的搜索弹出窗口，它有患者姓名部分和历史部分两部分。 popupextender由图像按钮和OnClick代码隐藏：
触发protected void imgSearchPrincipal_Click(object sender, ImageClickEventArgs e)
{
tblMedHistory.Visible = false;
upMedHistory.Update();
pnlMedSrchPrincipal_Ext.Show();
}
以下是弹出窗口的脚本：

<asp:Panel runat="server" ID="pnlMedSearch" >

此窗口弹出窗口就好了。但问题是当用户点击图像按钮（imgSearchPrincipal）时，我需要隐藏 tblMedHistory 。但是如果用户点击不同的图像按钮，我需要在弹出时显示 tblMedHistory 。当popextender调用div / panel时，我无法隐藏表格。任何解决方法？
谢谢，
答案 0 :(得分：0)
我想我终于解决了这个问题。我没有将ModalPopUpExtender的TargetControlID指向也触发表可见性的图像按钮，而是将TargetControlID引用到隐藏字段，所以现在imagebutton控制表的可见性以及通过代码隐藏而不使用弹出窗口更新面板
