OnAfterActiveDayChanged Method

Raises the AfterActiveDayChanged event when the ActiveDay is changed.
Syntax
'Declaration
 
Protected Overridable Sub OnAfterActiveDayChanged( _
   ByVal e As AfterActiveDayChangedEventArgs _
) 
protected virtual void OnAfterActiveDayChanged( 
   AfterActiveDayChangedEventArgs e
)

Parameters

e
A AfterActiveDayChangedEventArgs that provides data for the event.
Remarks

Raising an event invokes the event handler through a delegate.

The OnAfterActiveDayChanged method also allows derived classes to handle the event without attaching a delegate. This is the preferred technique for handling the event in a derived class.

Notes to Inheritors: When overriding OnAfterActiveDayChanged in a derived class, be sure to call the base class's OnAfterActiveDayChanged method so that registered delegates receive the event.

Example
This example displays information about the new active day after it changes.

For an overview of how to handle events in Visual Basic or Visual C#, see Event Handlers in Visual Basic and Visual C#. For specific information and code examples illustrating how to consume events in your application, see Consuming Events in the .NET Framework Developer's Guide.
