按照http://hi.baidu.com/yuye3618447378/blog/item/8972edfaf5fdb76d034f56f3.html上的代码做的网页，不报错，VS已经安装了AjaxControlToolkit，在左边的工具箱里建立了AjaxControlToolkit选项卡。但是Mathon运行之后，页面点击“LinkButton1”没有弹出窗口，怎么解决？多谢！

这个就是页面代码，因为是初学，我也不大拿得准什么是重要的还是不够相关的，大侠们，拜托了

多谢koukoujiayi，我才好不容易弄了个弹出窗口~~~ 吼吼
把那个updatepanel的ChildrenAsTriggers设置为false
updatemode改成conditonal就成了
多谢大家！

我试了一下，可以弹出窗口，但是就是闪一下，“关闭”按钮都不用点，闪一下它自动就关闭了，为什么？还是说我的VS2008有问题？

楼上的
<cc1:ModalPopupExtender ID="Modal.......
</cc1:ModalPopupExtender>

根据你的机器可能要改成:
<asp:ModalPopupExtender ID="Modal.......
</asp:ModalPopupExtender>

给你一个弹出窗口的小例子,代码不长,拷贝就可以用:

    <form id="form1" runat="server">

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

    </asp:ScriptManager>

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

        <ContentTemplate>

            <asp:Button ID="Button1" runat="server" Text="打开" />

            <cc1:ModalPopupExtender ID="ModalPopupExtender1" runat="server" 

                CancelControlID="Button2" PopupControlID="Panel1" TargetControlID="Button1">

            </cc1:ModalPopupExtender>

            <asp:Panel ID="Panel1" runat="server" BackColor="#CCCCCC" Height="200px" 

                Width="300px" style="display:none">

                AJAX弹出窗口<asp:Button ID="Button2" runat="server" Text="关闭" />

            </asp:Panel>

        </ContentTemplate>

    </asp:UpdatePanel>

    </form>

我加了一段：
<asp:UpdatePanel ID="UpdatePanel1" runat="server">
<ContentTemplate>

</ContentTemplate>
</asp:UpdatePanel>
但是依然不好使，崩溃中……

必须要有updatepanel么？要是用不上它也要么？

用微软的AJAX,页面代码必须有:
1. <asp:ScriptManager ID="ScriptManager2" runat="server">
</asp:ScriptManager>

2. <asp:UpdatePanel ID="UpdatePanel1" runat="server">
<ContentTemplate>
................
</ContentTemplate>
</asp:UpdatePanel>

楼主第2条没有!!

<asp:Button ID="LinkButton1" runat="server" Text="单击" />//这个就是触发弹出窗口的按钮

<asp:ModalPopupExtender ID="ModalPopupExtender" runat="server" TargetControlID="LinkButton1" PopupControlID="Panel1" BackgroundCssClass="modalBackground" OkControlID="OkButton" OnOkScript="onOk()" CancelControlID="CancelButton" DropShadow="true" Drag="true" PopupDragHandleControlID="Panel2">
</asp:ModalPopupExtender>

额代码太多我贴到空间里吧~~ 好长我觉得哪都挺重要的牵一发而动全身呵~~
