OnVisibleMonthsChanged Method (UltraMonthViewMulti)

Raises the VisibleMonthsChanged event after the UltraMonthViewMultiBase.VisibleMonths have been changed.
Syntax
'Declaration
 
Protected Overrides Sub OnVisibleMonthsChanged( _
   ByVal e As EventArgs _
) 
protected override void OnVisibleMonthsChanged( 
   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 OnVisibleMonthsChanged 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 OnVisibleMonthsChanged in a derived class, be sure to call the base class's OnVisibleMonthsChanged method so that registered delegates receive the event.

Example
This example displays the names of the new months being displayed by the control after the visible months have changed.

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.
