>I am looking for a way to keep the Valid event on a TextBox from firing if I click on a navigation button (cmdCancel). There is code behind the Valid Event of the Textbox that requires data entry. However, if the user clicks cmdCancel I want the form to stop everything do all TableReverts without caring about whether or not there is text in the current TextBox that has the focus. I could not find anything written that describes how to keep some event from firing.

Eric,
Set the Cancel property of the CmdCancel button to .T.. In the Valid event of the textbox, check to see if ESC was pressed. Ex.

if lastkey() = 27 then
   return .T.
endif

* do validation processing here

The Cancel property causes the button to act as if the user hit the Escape key.

HTH.
