Silverlight 2 Beta 1 Calendar and DatePicker Starter Guide

There are a few controls that was shipped in Silverlight 2 Beta 1 that was not available in WPF. Therefore I decided to write a starter guide to help you get started in using the controls. Here are some highlights of the Silverlight 2 Beta 1 Calendar and DatePicker control:

  • Supports nullable DateTime

  • Supports Silverlight's template model

  • Ability to set which Month/Year to display by default

  • Ability to select a single date

To get started with the Calendar and DatePicker:

1)      Instantiate a Calendar or a DatePicker in XAML & C# (See Figure 1)


<Calendar x:Name="cal" />

<DatePicker x:Name="datePicker" />


Calendar cal = new Calendar();

DatePicker datePicker = new DatePicker();

2)      Setting which Month/Year to display by default (See Figure 2)


cal.DisplayDate = new DateTime(2010, 4, 15);

datePicker.DisplayDate = new DateTime(2010, 4, 15);

3)      Setting which mode to display by default (See Figure 2)


cal.DisplayMode = CalendarMode.Year;

4)      Setting the default Selected Date


cal.SelectedDate = new DateTime(2008, 1, 1);

5)      Setting the range of dates that the Calendar or DatePicker can display

//C#  Displaying only a few days within a month

cal.DisplayDateStart = new DateTime(2008, 4, 9);

cal.DisplayDateEnd = new DateTime(2008, 4, 15);

datePicker.DisplayDateStart = new DateTime(2008, 4, 9);

datePicker.DisplayDateEnd = new DateTime(2008, 4, 15);

//C# Displaying a few month within a year

cal.DisplayDateStart = new DateTime(2008, 2, 1);

cal.DisplayDateEnd = new DateTime(2008, 11, 1);

datePicker.DisplayDateStart = new DateTime(2008, 2, 1);

datePicker.DisplayDateEnd = new DateTime(2008, 11, 1);


6)      Setting the range of dates that the Calendar or DatePicker can select


cal.SelectableDateStart = new DateTime(2008, 4, 11);

cal.SelectableDateEnd = new DateTime(2008, 4, 13);

datePicker.SelectableDateStart = new DateTime(2008, 4, 11);

datePicker.SelectableDateEnd = new DateTime(2008, 4, 13);

  6. Atul Gupta says:

    Is the DisplayStartDate initialized only once. I have set it once in code and when I try to change that later, it doesn’t.

  7. Atul Gupta says:

    An update to my earlier comment. It is working fine. I am able to change the DisplayStartDate repeatedly. Not sure why it wasn’t working earlier !! 🙂
