DateRangeEventArgs Class
Provides data for the DateChanged or DateSelected events of the MonthCalendar control.
Assembly: System.Windows.Forms (in System.Windows.Forms.dll)
The DateRangeEventArgs type exposes the following members.
| Name | Description | |
|---|---|---|
![]() | Equals(Object) | Determines whether the specified Object is equal to the current Object. (Inherited from Object.) |
![]() | Finalize | Allows an object to try to free resources and perform other cleanup operations before it is reclaimed by garbage collection. (Inherited from Object.) |
![]() | GetHashCode | Serves as a hash function for a particular type. (Inherited from Object.) |
![]() | GetType | Gets the Type of the current instance. (Inherited from Object.) |
![]() | MemberwiseClone | Creates a shallow copy of the current Object. (Inherited from Object.) |
![]() | ToString | Returns a string that represents the current object. (Inherited from Object.) |
The DateChanged event occurs when the currently selected date or range of dates changes; for example, when the user explicitly changes a selection within the current month or when the selection is implicitly changed in response to next/previous month navigation. The DateSelected event occurs when the user explicitly changes a selection. The DateRangeEventArgs constructor specifies the start and end for the new date range that has been selected.
For more information about handling events, see Consuming Events.
The following example displays a form containing a MonthCalendar control that displays one calendar year. The example demonstrates setting properties like BackColor, ForeColor, TitleBackColor, TitleForeColor, CalendarDimensions, and TrailingForeColor to customize the look of the calendar control. Other properties like AnnuallyBoldedDates, BoldedDates, and MonthlyBoldedDates are set to customize which dates are bolded. The example also sets properties to change the calendar format, including FirstDayOfWeek, MaxDate, MinDate, and MaxSelectionCount. The DateSelected and DateChanged events are also handled and their status displayed on the form.
