Namespace:   System.Web.Security
Assembly:  System.Web (in System.Web.dll)


public sealed class FormsAuthenticationEventArgs : EventArgs


Initializes a new instance of the FormsAuthenticationEventArgs class.


Gets the HttpContext object for the current HTTP request.


Gets or sets the IPrincipal object to be associated with the current request.

The FormsAuthenticationEventArgs class is used to supply event values to the FormsAuthentication_OnAuthenticate event and to enable you to specify a custom identity for the current request.

The FormsAuthenticationModule constructs a FormsAuthenticationEventArgs object using the current HttpContext and passes it to the FormsAuthentication_OnAuthenticate event.

You can use the User property to set the User property of the current HttpContext to a custom IPrincipal object.

If you do not specify a value for the User property during the FormsAuthentication_OnAuthenticate event, the identity supplied by the forms authentication ticket in the cookie or URL is used.

The FormsAuthentication_OnAuthenticate event is only raised when the authentication Mode is set to Forms and the FormsAuthenticationModule is an active HTTP module for the application.

The following code example uses the FormsAuthentication_OnAuthenticate event to set the User property of the current HttpContext to a GenericPrincipal object with a custom Identity.
