Regular Expression for numeric field in Asp.net 2.0 & 3.5

Any new developer needed to understand importance of the validation in their application to avoid future errors or bug in application. For this purpose developer must ensure the user input to their application is proper and well handled to avoid future bug or error in the application.
In the list of validation the important validation is numeric validation. in numeric validation user must enter or application must prompt the user to enter only numeric field. In asp.net we/developer normally use the Regular Expression Validation but proper regulion expression is as follows
  • ^\d*[0-9](|.\d*[0-9]|,\d*[0-9])?$
    Use this to restrict the user to enter Only numeric field
    give me ur feedback if any
    Enjoy
