title: DevExpress Date Picker Without Day
body: <p>I want to catch the event when the date is picked up<br>
  and when the day pick appear the control should close<br>
  (I just want to select the year and month <strong>but not the day</strong>) </p>
  
  <p>and show on text just the month and the year (display value)</p>
  
  <p>if this is possible<br>
