>I am trying to create my own custom controls using both the Control and Container object. I am using the LostFocus event to validate my custom control by setting the focus back into the control if it is not valid. This almost works, but like usual VFP has to spoil things. Checkboxes can still be checked outside of my control and the Form can be closed even if the data is invalid.

Yes, use the VALID event, not LOSTFOCUS.
