XafApplication.LoggedOn Event

Occurs after an end-user has logged on.

Namespace: DevExpress.ExpressApp

Assembly: DevExpress.ExpressApp.v21.2.dll

Declaration

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.

Remarks

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.

Note

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.

The following code snippet (auto-collected from DevExpress Examples) contains a reference to the LoggedOn event.
