title: A DateTimePicker to change only month and year
body: <p>UI should remain same I don't want to do this:  </p>
  
  <pre><code>dateTimePicker1.Format = DateTimePickerFormat.Custom;
  dateTimePicker1.CustomFormat = "mm-yyyy";
  dateTimePicker1.ShowUpDown = true; 
  </code></pre>
  
  <p>A User can pick the year and month, change DateTimePicker to Month/Year picker, the MonthCalendar too.<br>
  I don't want to use a third-party control but I will if it will be the only answer point me to any free month/year picker control.  </p>
