这是我的cs页面：

protected void btnCreateBill_Click(object sender, EventArgs e)
    {
        ModalPopUpExtender1.Show();
        DisplayReport();

    }

为什么单击btnCreateBill时不显示UpdatePanel1？当我单击btnCreateBill时，我想将UpdatePanel1显示为弹出窗口 当我将它放在我的内部时，它给出了错误扩展器不能与它扩展的控件位于不同的 UpdatePanel 中。modal pop up extenderupdatepanel1

因为它在更新面板之外，所以将它带入更新面板以使其出现。在更新面板中触发事件时，您无法访问和更改更新面板之外的控件状态。

在更新面板中触发事件时，只能访问和修改更新面板中的控件。

 <asp:UpdatePanel ID="UpdatePanel1" runat="server">

而不是在 modalpopup 面板上使用 updatepanel ，您可以尝试从后面的代码中进行某些操作来达到目的。

                <asp:scriptmanager id="ScriptManager1" runat="server">
                </asp:scriptmanager>

                 <asp:ModalPopupExtender ID="ModalPopupExtender1" runat="server" BackgroundCssClass="modalBackground"
                CancelControlID="btnCancel" PopupControlID="Panel1" 
                TargetControlID="HiddenField1">
                </asp:ModalPopupExtender>

            <asp:Panel ID="Panel1" runat="server" CssClass="Panel">

            <asp:RadioButtonList ID="RadioButtonList1" runat="server" Height="34px" RepeatDirection="Horizontal"
                                                Width="129px" OnSelectedIndexChanged="RadioButtonList1_SelectedIndexChanged"
                                                AutoPostBack="True">
                                                <asp:ListItem>Option1</asp:ListItem>
                                                <asp:ListItem>Option2</asp:ListItem>
                                            </asp:RadioButtonList>

        <asp:TextBox ID="txt1" runat="server" 
                                            Visible="False"></asp:TextBox>
                                        <asp:TextBox ID="txt2" runat="server"
                                            Visible="False"></asp:TextBox>    

             </asp:Panel>

    Code Behind:

     protected void RadioButtonList1_SelectedIndexChanged(object sender, EventArgs e)
        {
            if (RadioButtonList1.SelectedIndex == 0)
            {
                txt1.Visible = true;
                ModalPopupExtender1.Show();

            }
            else
            {
                txt2.Visible = true;
                ModalPopupExtender1.Show();
            }
        }
