Calendar::OnVisibleMonthChanged Method
Raises the VisibleMonthChanged event of the Calendar control and allows you to provide a custom handler for the VisibleMonthChanged event.
Assembly: System.Web (in System.Web.dll)
protected: virtual void OnVisibleMonthChanged( DateTime newDate, DateTime previousDate )
Parameters
- newDate
- Type: System::DateTime
A System::DateTime that represents the month currently displayed in the Calendar.
- previousDate
- Type: System::DateTime
A System::DateTime that represents the previous month displayed by the Calendar.
The VisibleMonthChanged event is raised when the user clicks the next or previous month navigation elements on the title section.
Raising an event invokes the event handler through a delegate. For more information, see Events and Delegates.
The OnVisibleMonthChanged 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 OnVisibleMonthChanged in a derived class, be sure to call the base class's OnVisibleMonthChanged method so that registered delegates receive the event.
The following code example demonstrates how to specify and code a handler for the VisibleMonthChanged event to display whether the Calendar has moved forward or backward one month.
