Regular Expression: ((\d{1,2},)?(\d {3},)*(\d{1,3}) )|(\d+)

I have a textbox that should allow 123,123,123,123 ,123,1 format.TextBox MaxLength is 21.The Problem is it should accept when you give 1(or)12(or)123( or)123,1(or)123 ,12(or)123,123( or)123,123,1(or )123,123,12(or) 123,123,123 same format for the rest.

It is Working fine when u put a RegularExpressi onValidator Control in the Form.But ,our requirement is to get the Expression...
