Age validation in asp.net

Hello Friends,

Recently i have requirement to validate sign up age +18. I have search many sites to how it will calculate age on date. I found simple RangeValidator to accomplish this.


Now, in back end set RangeValidator minimum date and maximum date. To set it use following

rvDOB.MinimumValue = DateTime.Today.AddYears(-60).ToString("MM/dd/yyyy");
rvDOB.MaximumValue = DateTime.Today.AddYears(-18).ToString("MM/dd/yyyy");

You can set your years in AddYears as per your requirement. Hope it will help you!!!
