I have 3 fields on the page. There is also a Save button. When the user changes the text in a field, I want the button to become
enabled. Even if it was already enabled, I would not want to push data back to the server that has not changed. So, to answer the
question, I want to know that data has changed. I am trying to use the TextChanged event to store a mode as a session var so I know
what happened.

I'm wide open to suggestion.
Everything makes sense in someone's mind
