前台代码:
[code]<asp:ScriptManager ID="ScriptManager1" runat="server">
        </asp:ScriptManager>
        <asp:UpdatePanel ID="UpdatePanel1" runat="server">
            <ContentTemplate>
                <asp:TextBox ID="TextBox1" runat="server" TextMode="MultiLine"></asp:TextBox><br />
                <asp:Button ID="Button1" runat="server" OnClick="Button1_Click" Text="Button" />
            </ContentTemplate>
        </asp:UpdatePanel>[/code]
当我在TextBox1输入＜p＞test＜/p＞,保存时就会出错;
错误信息:
Sys.WebForms.PageRequestManagerServerErrorException: An unknown error occurred while processing the request on the server. The status code returned from the server was: 500
