请教一个LOGIN控件的问题

Question

我向页面拖拽了一个LOGIN控件，然后模板化，修改，得到下面的代码
<asp:Login ID="Login1" runat="server" BackColor="White" BorderColor="Green" BorderPadding="4" BorderStyle="Solid" BorderWidth="1px" Font-Names="Verdana" Font-Size="0.8em" ForeColor="#333333" TextLayout="TextOnTop">
            <TitleTextStyle BackColor="#990000" Font-Bold="True" Font-Size="0.9em" ForeColor="White" />
            <InstructionTextStyle Font-Italic="True" ForeColor="Black" />
            <TextBoxStyle Font-Size="0.8em" />
            <LoginButtonStyle BackColor="White" BorderColor="#CC9966" BorderStyle="Solid" BorderWidth="1px"
                Font-Names="Verdana" Font-Size="0.8em" ForeColor="#990000" />
            <LayoutTemplate>
                <table border="0" cellpadding="4" cellspacing="0" style="border-collapse: collapse">
                    <tr>
                        <td style="height: 186px">
                            <table border="0" cellpadding="0">
                                <tr>
                                    <td align="center" style="font-weight: bold; font-size: 0.9em; color: white; height: 28px;
                                        background-color: #008f00">
                                        后 台 登 录</td>
                                </tr>
                                <tr>
                                    <td>
                                        <asp:Label ID="UserNameLabel" runat="server" AssociatedControlID="UserName">用户名:</asp:Label></td>
                                </tr>
                                <tr>
                                    <td>
                                        <asp:TextBox ID="UserName" runat="server" Font-Size="0.8em"></asp:TextBox>
                                        <asp:RequiredFieldValidator ID="UserNameRequired" runat="server" ControlToValidate="UserName"
                                            ErrorMessage="必须填写“用户名”。" ToolTip="必须填写“用户名”。" ValidationGroup="Login1">*</asp:RequiredFieldValidator>
                                    </td>
                                </tr>
                                <tr>
                                    <td>
                                        <asp:Label ID="PasswordLabel" runat="server" AssociatedControlID="Password">密码:</asp:Label></td>
                                </tr>
                                <tr>
                                    <td>
                                        <asp:TextBox ID="Password" runat="server" Font-Size="0.8em" TextMode="Password"></asp:TextBox>
                                        <asp:RequiredFieldValidator ID="PasswordRequired" runat="server" ControlToValidate="Password"
                                            ErrorMessage="必须填写“密码”。" ToolTip="必须填写“密码”。" ValidationGroup="Login1">*</asp:RequiredFieldValidator>
                                    </td>
                                </tr>
                                <tr>
                                    <td>
                                        <asp:CheckBox ID="RememberMe" runat="server" Text="下次记住我。" />
                                    </td>
                                </tr>
                                <tr>
                                    <td align="center" style="color: red">
                                        <asp:Literal ID="FailureText" runat="server" EnableViewState="False"></asp:Literal>
                                    </td>
                                </tr>
                                <tr>
                                    <td align="right">
                                        <asp:Button ID="LoginButton" runat="server" BackColor="Transparent" BorderColor="Green"
                                            BorderStyle="Solid" BorderWidth="1px" CommandName="Login" Font-Names="Verdana"
                                            Font-Size="0.8em" ForeColor="Green" Height="26px" OnClick="LoginButton_Click"
                                            Text="登　录" ValidationGroup="Login1" Width="82px" />
                                    </td>
                                </tr>
                            </table>
                        </td>
                    </tr>
                </table>
            </LayoutTemplate>
        </asp:Login>现在我想通过他们实现登录功能，我所写的.aspx.cs的代码是
protected void LoginButton_Click(object sender, EventArgs e)
    {
 string user_name = Request.Params["UserName"];
        string user_pwd = Request.Params["Password"];
        Response.Write(user_name);
        Response.Write(user_pwd);
}我发现获取不到这些相关的值，请问正确的写法是？谢谢

Answer 1

string user_name =  UserName.Text;

Answer 2

UserName这个ID能直接找到么？

Answer 3

UserName是在Login1里的控件,他在客户端的name已经是Login1$UserName,同样Password在客户端的name是Login1$Password

Answer 4

应该是通过Login1来访问：
string user_name = Login1.UserName;
string password = Login1.Password;

Answer 5

同楼上，用Request这种传统的方式在这个案例中没有必要

Answer 6

    void user_login(object sender,AuthenticateEventArgs e) 
    {
        string name = ((System.Web.UI.WebControls.Login)sender).UserName;
        string psw = ((System.Web.UI.WebControls.Login)sender).Password;
    }
