For client side validation I'd suggest you use the following javascript function: function validate() { var tb = document.getElementById( ); // use actual TextBox ID var dob = tb.value; var type = document.getElementById( ).value; // use actual DDL ID var dt = Date.parse(dob); if (isNaN(dt)) { alert(Not a valid date); tb.focus(); return false; } var dt1; var dt2; var isValid; switch (type.toLowerCase()) { case general man: dt1 = new Date(1980 0 1); dt2 = new Date(1997 0 1); break; case sc/st/obc/stc: dt1 = new Date(1975 0 1); dt2 = new Date(1997 0 1); break; case divorce women: dt1 = new Date(1890 0 1); //nobody'd going to be 125 or more dt2 = new Date(1997 0 1); break; case handicapped general man: dt1 = new Date(1970 0 1); dt2 = new Date(1997 0 1); break; case handicapped obc: dt1 = new Date(1967 0 1); dt2 = new Date(1997 0 1); break; case handicapped sc/st: dt1 = new Date(1965 0 1); dt2 = new Date(1997 0 1); break; default: alert(Not a supported type); return false; } isValid = dt1 if (!isValid) { alert(Date is out of range); tb.focus(); return false; } return true; } In the button you press to validate the textbox input you'll then need to add the following attribute: onclientclick=return validate();

Here's a C# routine you could use for server side validation: public bool ValidateAge(TextBox tb string type) { DateTime dt; bool isValid = DateTime.TryParse(tb.Text out dt); if (!isValid) return false; DateTime dt1 dt2; switch(type.ToLower()) { case general man : dt1 = new DateTime(1980 1 1); dt2 = new DateTime(1997 1 1); return dt1 case sc/st/obc/stc : dt1 = new DateTime(1975 1 1); dt2 = new DateTime(1997 1 1); return dt1 case divorce women : dt1 = DateTime.MinValue; dt2 = new DateTime(1997 1 1); return dt1 case handicapped general man : dt1 = new DateTime(1970 1 1); dt2 = new DateTime(1997 1 1); return dt1 case handicapped obc : dt1 = new DateTime(1967 1 1); dt2 = new DateTime(1997 1 1); return dt1 case handicapped sc/st : dt1 = new DateTime(1965 1 1); dt2 = new DateTime(1997 1 1); return dt1 default : return false; } }
