            </ContentTemplate>
        </asp:UpdatePanel>
    </form>
</body>如上的Html所示，点击按钮应该是独自刷新的，但是现在整张网页都会刷新

解决方案 »

  1.   

            <asp:UpdatePanel ID="UpdatePanel1" runat="server" UpdateMode="Conditional">             <ContentTemplate> 
                    <asp:Button ID="Button1" runat="server" OnClick="Button1_Click" Text="Button" /> 
                    <asp:Label ID="Label1" runat="server" Text="Label"> </asp:Label> 
                </ContentTemplate> 
                
                <Triggers> 
                    <asp:AsyncPostBackTrigger ControlID="Button1" EventName="Click" /> 
                </Triggers> 
            </asp:UpdatePanel> 
      

  2.   

            <asp:UpdatePanel ID="UpdatePanel1" runat="server" UpdateMode="Conditional">             <ContentTemplate> 
                    <asp:Button ID="Button1" runat="server" OnClick="Button1_Click" Text="Button" /> 
                    <asp:Label ID="Label1" runat="server" Text="Label"> </asp:Label> 
                </ContentTemplate> 
                
                <Triggers> 
                    <asp:AsyncPostBackTrigger ControlID="Button1" EventName="Click" /> 
                </Triggers> 
            </asp:UpdatePanel>

    问一个问题，为什么UpdateMode 用不了？
      

  4.   

    ScriptManager 放在form外面吧
      

  5.   

    我的代码和你的完全一样，在我这里可以啊。
    你安装.net3 或者net3.5了吗？<%@ Page Language="C#" AutoEventWireup="true" CodeBehind="WebForm3.aspx.cs" Inherits="CSDNWeb.WebForm3" %>

                    <%= DateTime.Now %>
                    <asp:Button ID="Button1" runat="server" Text="Button" />
                </ContentTemplate>    </asp:UpdatePanel>
        <asp:UpdatePanel ID="UpdatePanel2" runat="server" UpdateMode="Conditional">
        <ContentTemplate >

            <asp:Button ID="Button2" runat="server" Text="Button" />
