名字就是ASP.Login，在這個控制項中有兩個常用的Event， OnAuthenticate就是核實登入密碼的，OnLoggedIn 就是管理登入後的事，比如Cookies，跳轉到頁面等等。
頁面布置都放在下面的<LayoutTemplate>之中， 登入時候點擊的按鈕要聲明，CommandName="Login" 這樣按鈕就和前面的事件聯絡起來了。此外，在OnAuthenticate的事件響應中，Argument是AuthenticateEventArgs，把這個變數的e.Authenticated屬性設定為True，就可以標誌使用者已經進入系統的。反之，就是被拒絕。
在網頁中，用this.User.Identity.IsAuthenticated來檢查使用者的Login狀態。

asp.net login control
1. event OnAuthenticate: check login name and password, if ok, set e.Authenticated to true
protected void Login_User_Authenticate(object sender, AuthenticateEventArgs e)
{
bool Authenticated = false;
string compoundName = ConvertUserName(this.Login_User.UserName);
Authenticated = AuthenticateUser(compoundName, this.Login_User.Password);
e.Authenticated = Authenticated;
}
2. event OnLoggedIn
check if remember me on this computer. If it is, set cookies
