Dynamically adding SelectedDateChanged event to Calendar in WPF

Question

I want my form to include a date picker.  So, upon clicking a button, a Calendar control is created and added.  This Calendar control (called cldrDateOfData) should have an event handler added which will fire when a date is selected in the Calendar.

So, I assume the button's event will look something like

            Calendar cldrDateOfDate = new Calendar();
            cldrDateOfDate.Height = 170;
            cldrDateOfDate.HorizontalAlignment = HorizontalAlignment.Left;
            cldrDateOfDate.Margin = new Thickness(101, 31, 0, 0);
            cldrDateOfDate.Name = "cldrDateOfData";
            cldrDateOfDate.VerticalAlignment = VerticalAlignment.Top;
            cldrDateOfDate.Width = 180;
            cldrDateOfDate.DisplayMode = CalendarMode.Year;
            cldrDateOfDate.Visibility = System.Windows.Visibility.Visible;
            cldrDateOfDate.SelectedDatesChanged += new EventHandler<SelectionChangedEventArgs>(SelectDateOfData);

but I'm not sure how the SelectDateOfData method should look.  How do I pull out the date that was selected from the cldrDateOfData control?

In Visual Studio, to complete an event handler, just type the "+=", then wait. intellisense will kick in and offer to create the event handler, just press Tab to create it.

This is what it produces:

        public CalenderPage()
        {
            InitializeComponent();

            Calendar cldrDateOfDate = new Calendar();
            cldrDateOfDate.Height = 170;
            cldrDateOfDate.HorizontalAlignment = HorizontalAlignment.Left;
            cldrDateOfDate.Margin = new Thickness(101, 31, 0, 0);
            cldrDateOfDate.Name = "cldrDateOfData";
            cldrDateOfDate.VerticalAlignment = VerticalAlignment.Top;
            cldrDateOfDate.Width = 180;
            cldrDateOfDate.DisplayMode = CalendarMode.Year;
            cldrDateOfDate.Visibility = System.Windows.Visibility.Visible;
            cldrDateOfDate.SelectedDatesChanged += new EventHandler<SelectionChangedEventArgs>(cldrDateOfDate_SelectedDatesChanged);
        }

        void cldrDateOfDate_SelectedDatesChanged(object sender, SelectionChangedEventArgs e)
        {
           
        }

You can find out more about the event args here: http://msdn.microsoft.com/en-us/library/system.windows.controls.selectionchangedeventargs.selectionchangedeventargs.aspx

And I'm sure that should give you enough clues to find the rest of what you need.

Good luck!
