Hi Anton,
There's a TextChanged event that fires when the text is changed. You can do
stuff inside its handler. Here's a little sample that might get you going.
Let us know if this helps?

Hello folks,
is there an easy way of finding out wether a user has changed a value of a
webcontrol (eg textbox or checkboxlist).
Thanks
