Namespace: DevExpress.ExpressApp

Assembly: DevExpress.ExpressApp.v18.2.dll


public event EventHandler<LogonEventArgs> LoggedOn

Event Data

The LoggedOn event's data class is LogonEventArgs. The following properties provide information specific to this event:

Property Description
LogonParameters Gets the current logon parameters.


Handle this event to execute custom code after a logon has been performed, the SecuritySystem object is initialized, the logon parameters have been saved and user model differences are loaded.


Exceptions that occur within the LoggedOn event handler are not handled by XafApplication automatically, because it is too late to cancel a logon when this event occurs. So, it is recommended that you wrap your handler code into try-catch blocks.
