Hi!

I also go for option to use Cancel=.T. for button. It does not matter that field value changes are lost when user press ESC key - you will cancel anyway, and in most interfaces pressing cancel does not prompt user for confirmation. So, wonder why this is an issue?

BTW, This is also a common problem (like it was with value of field not saved when saving data from toolbar or hotkey that we discussed in recent thread). And, as usual, many frameworks has workarounds for this.

In our framework we created special generic approach for this, but we did not dived so deep into generalizing things. We have a propery to specify Cancel button object location (starting from thisform object). Then we just had a generic method in the form class that using coordinates of mouse and coordinates of button determine if that button is pressed by mouse. Also, check for all other things like ESC or hotkey or whatever. Remember that Cancel button could go with image, as well as a hot key for it could be not always "C".
