VS2008最基本用法updatepanel

（最重要的是要添加ScriptManager 控件）不说了，直接看码：

aspx:

        <asp:Button ID="Button1" runat="server" Text="Button" onclick="Button1_Click" />
        <br />
        <asp:ScriptManager ID="ScriptManager1" runat="server">
        </asp:ScriptManager>
        <br />
        <br />
        <asp:UpdatePanel ID="UpdatePanel1" runat="server">
            <ContentTemplate>
                <asp:Label ID="lblname" runat="server" Text="名字"></asp:Label>
                <br />
                <br />
            </ContentTemplate>
            <Triggers>
             <asp:AsyncPostBackTrigger ControlID="Button1" EventName="Click" />
            </Triggers>
           
        </asp:UpdatePanel>

cs码：

   protected void Button1_Click(object sender, EventArgs e)
        {
            lblname.Text = "dddd";
        }
