Question

我有一个未被调用的函数。我尝试使用调试来编写文件，它正确地写了第一个调试消息"debug0"。但不是其他消息。

这是aspx：

<%@PageLanguage="C#"AutoEventWireup="true" CodeFile="Login.aspx.cs" Inherits="Login" %>

<!DOCTYPE html PUBLIC >

<html>
    <head runat="server">
        <title/>
        <link rel="stylesheet" type="text/css" href=".//style.css" />
    </head>
    <body>
        <form class="container" runat="server">
            <asp:login id="Login1" runat="server" style="width: 100%;">
                <LayoutTemplate>
                    <div id="content">
                        <h1>blah<br>Site Login </h1>
                        <asp:TextBox class="field" placeholder="Username" ID="username" runat="server"> </asp:TextBox>
                        <asp:RequiredFieldValidator ID="UserNameRequired" runat="server" ControlToValidate="UserName" ErrorMessage="User Name is required." ToolTip="User Name is required." ValidationGroup="Login1">*
                        </asp:RequiredFieldValidator>
                        <br>
                        <asp:TextBox class="field" placeholder="Password" ID="password" runat="server" TextMode="Password"/>
                        <asp:RequiredFieldValidator ID="PasswordRequired" runat="server" ControlToValidate="Password" ErrorMessage="Password is required." ToolTip="Password is required." ValidationGroup="Login1">*
                        </asp:RequiredFieldValidator>
                        <br>
                        <asp:Button class="btn" ID="LoginButton" runat="server" CommandName="Login" Text="Log In" ValidationGroup="Login1"/>
                        <br>
                        <asp:Literal ID="FailureText" runat="server" EnableViewState="False"/>
                    </div>
                </LayoutTemplate>
            </asp:login>
        </form>
    </body>
</html>

您似乎错过了在asp.net标记中绑定事件

   <asp:login 
       id="Login1" 
       runat="server" 
       style="width: 100%;"
       OnAuthenticate="Login1_Authenticate">

c＃函数未被调用
