Namespace: DevExpress.ExpressApp

Assembly: DevExpress.ExpressApp.v19.2.dll


public event EventHandler<LogonEventArgs> LoggedOn
Public Event LoggedOn As EventHandler(Of LogonEventArgs)

Event Data

The LoggedOn event handler receives an argument of the LogonEventArgs type. 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.

For an example, see How to: Show Notifications to a Specific User.


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.
