OnAfterSelectedDateRangeChange Method

Raises the AfterSelectedDateRangeChange event after a DateRange is removed from the SelectedDateRanges collection.
Syntax
'Declaration
 
Protected Overridable Sub OnAfterSelectedDateRangeChange( _
   ByVal e As EventArgs _
) 
protected virtual void OnAfterSelectedDateRangeChange( 
   EventArgs e
)

Parameters

e
A System.EventArgs that provides data for the event.
Remarks

Raising an event invokes the event handler through a delegate.

The OnAfterSelectedDateRangeChange 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.

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

Example
This example displays information about the currently selected days.

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.
