After reading this thread (http://tinyurl.com/3c6358) that I know WPF doesn't
provide MonthCalendar control and DateTimePicker control, but I can use the
Kevin's Bag-O-Tricks open source DateTimePicker control. After checking some
books and websites, I found another way to use the MonthCalendar and
DateTimePicker using WPF, it suggests me to add the "ElementHost" component
and put the "WindowsFormHost" component into an instance of Elementhost, then
we could use the MonthCalendar or DateTimePicker control, but I failed to do
with it(I can't find the ElementHost component in ToolBox and I can't use the
WindowsFormHost to contain the MonthCalender control).

// Here's the code
Expander expander = new Expander();
expander.Header = "WPF Header";
WindowsFormHost host = new WindowsFormHost();
host.Child = new MonthCalendar();
expander.Content = host;
elementHost.Child = expander;
