Has form be changed...

I have had a look for this on the forum, but could not find anything....

I have a userControl and what I want to be able to do is tell if any of the controls on the form have changed since I clicked a button.

e.g.

1) Set control values
2) Click button
3) Change control values
4) Click another button which tells me if the controls have changed since the button was clicked in stage 2

Thanks

Simon

If it is some specific controls and some specific properties you want to monitor, then you could keep them in any collection and check them whenever you want to.
