Asp.Net 2.0 - Textbox previous value

How do I get the previous value of a text box ? Is there a way to access
the TextBox control state ?

Thanks for any direction,
Steve

There are some clever tricks you can do with ViewState, but by far the
simplest (and 100% guaranteed) method is to include a hidden field
containing the initial value of the textbox and then compare the two at
postback:
