MultiSelectionCalendar Control
Back

The MultiSelectionCalendar control is a variation of the Calendar Control  that allows multiple selections. Use it when you need to store a list of dates. It has most of the same 200+ properties from the Calendar control including support for the SpecialDates Control  with its powerful formatting features and Multiple Month View.


Product Features

  • There are several selection modes:
    • Individual dates. When turned off, you can prevent selecting single dates. This lets you use the week, month, and day of week features exclusively.
    • By week
    • By month
    • By day of the week
    • Range. Keeps a contiguious selection between the earliest and latest dates.
    • Use the SHIFT key to extend the selection from the last cell selected.
  • You can limit the number of dates selection and show an alert when that limit is exceeded.
  • The Current Date Label can show the number of dates selected or the start and end dates.
  • One challenge users face with most multiple selection calendars is how to interact with it. This control introduces the Message Center, an interactive help section at the bottom of the control.
