Peter's Date and Time
Calendar Control
Back

The Calendar control initially appears to be like the native Calendar control provided with ASP.NET. But it goes in a new direction: client-side operation. The calendar fills in each month and manages the current selection using client side JavaScript that gives the user a faster, more interactive experience. It also means that you don’t require a post back just to select a date or change the month. Calendar can be included in your data entry forms and only post back when the user submits the form. That's just the start. Here are the features of this control.


Product Features

The extensive feature list is shown below. Test the features yourself in the Demos provided. This highly customizable control has well over 200 properties.

Appearance

  • Style sheet driven – Most elements, whether they are days in the month, controls, or areas of the calendar, have unique style sheet names. With so many names, setup is made very easy by a supplied style sheet file which the control uses by default. You simply edit the style sheet file and the appearance quickly changes, all without editing a single property.
    You can also replace the graphic buttons.

    The default calendar. The same calendar with alternative style sheet classes and different buttons.

  • There are three ways to move to another month. The classic movement is by one month. You can add additional movement commands to jump by a number of months of your choosing, such as a year. Plus the user can popup the MonthYearPicker, a control that quickly gets you to any month in any year.

    Right click to see the context menu.

  • Use the SpecialDates control to customize individual dates and make them unselectable. This very powerful tool can turn an ordinary calendar into a fancy schedule.
  • On Internet Explorer, users can use their keyboards to select commands and move the selected date around.
  • Days can optionally highlight with a different border and/or font color when the mouse passes over them.
  • On Internet Explorer, there are two animations: when changing months, it rotates or swaps calendars. When opening or closing any popup, the control fades in and out.

Other Features

  • Supports Databinding your date value to the control.
  • Impose date range limits so the user is compelled to enter a date within the range. Dates outside the range are unselectable. The MonthYearPicker and the month movement buttons all respect these limits.
  • All Peter's Date and Time controls use the System.Globalization.CultureInfo object to determine the extact format. So they are fully localizable.
  • Optionally post back when the user changes the selection or the month viewed.
  • ASP.NET 2.0 users can optionally use callbacks (AJAX type requests) to update the contents of the date cells when the month view changes.
  • Can update another control through a client side script that you provide or even a simple ID to the other field, if that field is a Label or TextBox.
  • Can be used as a popup when you select the PopupCalendar control.
  • Javascript programmers can use several published methods to interact with the control.
