onblur is a JavaScript function and I recommend against using JavaScript for anything that is required to happen. There is no guarantee that the JavaScript code will run in a users browser. Instead it is best to put the clean-up code in the submit function just before inserting it into the database. You can now be assured that the data will be formatted properly. An example clean-up algorithm:

' handle phone variations
If phone.Contains("(") Then
  ' extract digits
ElseIf phone.Contains("-") Then
  ' extract digits
...
End If

Do you have examples of the clean-up functions that changes the information into the correct format for storing in the database? Can this be done “onBlur”? I am very new at ASP.Net and have used regular expressions in javascript but am not sure how to reformat data input in ASP.Net.
