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