How do I make a date input mask (not format) for a DataGridView column?

Greetings to all,

I'm beginner programmer developing a small WinForms application in Visual Studio 2015 using C# .Net and need a date input mask (not format) for the  numbers entered in the first column of a DataGridView.  How do I go about doing that?  I'd really appreciate some sample code.  Thank you very much for your all your time and help.

Best regards,
