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
