Fired

Before the viewable area rendered by the calendar is changed. Generally the event is raised as a result of using the built-in navigation controls. The event is raised before the results are rendered, so that custom logic could be executed, and the change could be prevented if necessary. There is no way to find out whether the operation was accomplished successfully.

Arguments

calendarInstance - the Telerik RadCalendar instance that raised the event.

step - an integer that denotes the increment/decrement value to be calculated. This value is abstract, as it describes the count of "views" that the calendar needs to shift in order to produce a valid calendar presentation.

Can be cancelled

Yes, return false to cancel.

Example

ascx/aspx
