Not sure I get it right at the question is not very clear, but anyway :

You could just create Properties for you user controls, and assign Enums to them

 public enum My_UserControl_DateFormats
    {
        YYYYMMDD = 1,
        YYYYMMDDHH = 2,
        YYYYMMDDHHmmSS = 3
    }

And in the setter code of your properties handle the logic to assign the Date Format (For Example) according to the enum value (using switch/case)

It's one among many possibilities.
