Date Picker in WP8 set the range

Question

Hi,

 

I have added Date Picker in my windows phone app programmatically:-

this.datePicker = new DatePickerCustom();

this.datePicker.IsTabStop = false;

this.datePicker.MaxHeight = 0;

this.datePicker.ValueChanged += new EventHandler<DateTimeValueChangedEventArgs>(datePicker_ValueChanged);

LayoutRoot.Children.Add(this.datePicker);

dp.Text = DateTime.Now.ToString("d MMMM yyyy HH:mm:ss");

 

I want to limit the datepicker by setting a min and max date.How can I do it in Windows Phone 8?
