Accepted answer
Few things, if you are going to persist (store) this data in db, please store date of birth directly and not the age.
It is not clear, please clarify, first you are taking today's year, but then you are taking date of birth. May be you should take ONLY the year part of the Date of birth:
var birthyear = _obj.Dateofbirth.Year;
Another thing not clear is why divide by 1000?
Where data type is hugely predictable, such as this case, use explicit data type (such as Int32) and not var.

Furthermore, if you are interested only in age, why not have integer text box for input and not the date-time picker!
