Hi Folks,

I look for an idea to figure out what object on a form is the default one, i.e. the one that has the DEFAULT property true

Background:

I have a rather tricky grid that recieves the Enter key and performs stuff. Sometimes just some internal blabla, sometimes it performs an action directly bound to the key.

I think I can tetermine what of the above, but the problem is how to rise the default objects default action (Click) / or not. For the moment it's simply doing nothing with the default object

the code in the grid's textbox looks
 DO CASE
  CASE tnKeyCode = 13
*<Enter>
   NODEFAULT
  CASE INLIST(tnKeyCode,5,24) AND tnShiftAltCtrl=0
*<Up>,<Down>
   .SETFOCUS()
  CASE tnKeyCode = 27
*<ESC>
   NODEFAULT
...
If I compare with ESC I see no difference (even in the keypress stuff around objects keypress , since form is KeyPreview = .T.), this is checkes with SET COVERAGE.

Both keys just differ in the way they run throug this case.

After the keypress is ended, ESC raises the events that will end up with the Click of Cancel- object Enter just does nothing.

Well, I can not figure that out. O.K. But then, how do I raise default objects Click?

TIA
