>>>>>>>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.

>>>For example I allow the blanking of my date field. If I used the embedded textbox control validation the moment I blanked a month but still had a day and a year the months Valid would return .f. because " /12/1997" is not a valid date. So instead I allow blank month, day, or year and check to see if they are all blank or all filled when focus is lost from the container.

Why you don't fill the others sections of your date field with something valid?

If the user take the 'Year' part in your date picker you can fill the day and month with '01' if those parts are empty...?
