Currently in My application, validating the users using the ASP.Net membership provider and the ASP.Net default Login page contains only Username and Password. This is working fine with this two fields. But as per my current requirement, need an extra field "Company" display as dropdownlist in ASP.Net Login page and validate the three Company, Username and Password using the ASP.NET membership provider. Is this possible or not, customize the ASP.Net Login page with an extra field using ASP.Net membership provider? Could you please give me some ideas how could I approach?

推荐答案

成员资格提供程序的ValidateUser方法仅接受两个参数-用户名和密码.即使您覆盖它，也不能传递三个参数.

Membership provider's ValidateUser method only accept two parameters - username and password. Even if you override it, you cannot pass three parameters.

ValidateUser(string username, string password)

基本上，您不能使用登录控件来验证用户.相反，您想自己验证用户.这是示例代码-

Basically, you cannot use Login control to validate for user. Instead, you want to validate user by yourself. Here is an sample code -

注意:我出于演示目的在登录控件中删除了代码.

Note: I strip out codes in Login control for demo purpose.

<asp:Login ID="LoginUser" runat="server" OnAuthenticate="LoginUser_Authenticate">
    <LayoutTemplate>
        <asp:TextBox ID="UserName" runat="server" />
        <asp:TextBox ID="Password" runat="server" TextMode="Password" />
        <asp:DropDownList ID="CompanyDropDownList" runat="server">
            <asp:ListItem Text="One" Value="1" />
            <asp:ListItem Text="Two" Value="2" />
        </asp:DropDownList>
        <asp:Button ID="LoginButton" runat="server" CommandName="Login" 
        Text="Log In" ValidationGroup="LoginUserValidationGroup" />
    </LayoutTemplate>
</asp:Login>

protected void LoginUser_Authenticate(object sender, AuthenticateEventArgs e)
{
    var companyName = LoginUser.FindControl("CompanyDropDownList") 
        as DropDownList;

    if(MyValidateUser(LoginUser.UserName, LoginUser.Password, 
        companyName.SelectedValue))
    {
        FormsAuthentication.SetAuthCookie(LoginUser.UserName, false);

        // Do something
    }
}

请确保您使用新的 ASP.NET通用提供程序

Please make sure you use new ASP.NET Universal Providers
