title: Is it possible to restrict the WinForms DateTime Picker dropdown to only choose the month and year?
body: <p>I want to use the WinForms DateTime Picker to force user input specifically to the MM/YYYY format when entering expiration dates for credit cards.</p>
  
  <p>In the DateTimePicker I've found the CustomFormat option and set it to MM/yyyy and the Format option and set it to custom, which works well enough in that only the month and the year are getting displayed. Now I need to know how to either completely hide and disable the drop-down arrow, or make it so that when a user clicks it they can only select the month and the year from it (not the day).</p>
  
  <p>Is this possible in WinForms? I would be happy to completely disable the dropdown calendar if that's possible and if it's the only option</p>
