Login.LoginError Event

Occurs when a login error is detected.

Namespace:  System.Web.UI.WebControls
Assembly:  System.Web (in System.Web.dll)

public event EventHandler LoginError
<asp:Login OnLoginError="EventHandler" />

The LoginError event is raised when the credentials entered by the user are invalid. You can use the LoginError event to redirect the user to a custom error page, to offer additional help, or to log failed login attempts.

For more information about handling events, see Consuming Events.

The following code example uses the LoginError event to display Help links to the user when a login attempt fails.
