Public Event DateNavigatorQueryActiveViewType As DateNavigatorQueryActiveViewTypeHandler

Event Data

The DateNavigatorQueryActiveViewType event's data class is DateNavigatorQueryActiveViewTypeEventArgs. The following properties provide information specific to this event:

Property	Description
NewViewType	Gets or sets the type of the view to be used by the scheduler to show its data after the date range selected in the bound DateNavigator has been changed.
OldViewType	Gets the type of the view used by the scheduler to show its data before the date range selected in the bound DateNavigator is changed.
SelectedDays	Gets the collection of dates selected in the DateNavigator bound to scheduler.

Example

This example uses the SchedulerControl.DateNavigatorQueryActiveViewType event of the SchedulerControl to conditionally switch the Scheduler view. When an entire week is selected in the Date Navigator, the Scheduler switches to the Week View.
