>>Sorry, still doesn't work :( I see the button pressed, but my entry stays there :( Also I completely forgot how can I debug it. I press F5 but I can not see if it's running to the breakpoint, and I forgot what should I press to do step by step.

>It sounds like your event isn't hooked up anymore. If you have a breakpoint set in the event and it's not stopping there, the event isn't firing. Go to the page view of the form and click on the button. In the properties window click on the lightning bolt icon to view the events. Scroll down to Click - it should be filled in with the name of your event handler.

Thanks a lot, one problem less now.

New problem - if I use LostFocus - the finding of the item takes a long time and clicking on the Clear button or attempting to do anything else does nothing - any ideas of how to intercept?

Thanks a million again.
