Question

The existing .Net range attribute validator only accepts static string values. I would like to create a validator that accepts dynamic values. For example I would like the age range to be 16 years to 200. If I input the minimum birthday as 1996-today in a year from now the minimum age is now 17 and will continue to rise year after year.
Is this possible or should I just validate this manually in the view model?
Edit: I’m not using asp here, this is a desktop application.

Answer 1

I fixed this by using a CustomValidationAttribute. This Attribute is basically just a static method that does the validating and I put the min/max birthdate values in the method. Unfortunately this is the only way I could find to deal with the issue of wanting the dates to be dynamic.
