Start Date: - End Date:


  • This example demonstrates the range selection between dates. To enable range selection feature you need to set the RangeSelectionMode property to one of the following values:
    • OnKeyHold - Allow range selection by pressing [Shift] key and clicking on the date.
    • ConsecutiveClicks - Allow range selection by clicking consecutively two dates.
    By default the RangeSelectionMode property is set to None which does not allow range selection.

    The range selection Start/End dates are available:
    • On client through RadCalendar.get_rangeSelectionStartDate() and RadCalendar.get_rangeSelectionEndDate() functions
    • On server through RadCalendar.RangeSelectionStartDate and RadCalendar.RangeSelectionEndDate properties

    You could set dates in range programmatically by using:
    • RadCalendar.RangeSelectionStartDate and RadCalendar.RangeSelectionEndDate properties server side
    • RadCalendar.set_datesInRange(startDate, endDate) function client side

    Please note that when the dates in range are selected any other date selection will unselect all dates from range selection
