Menu Designer

Unlike most other controls, you cannot set the VISIBLE or ENABLED property for a MenuItem at run time. The only dynamic property available is to display a check mark:

For a menu item, the setting of SourceExpr must evaluate to boolean. TRUE means that the menu item will appear checked, FALSE that it will appear unchecked (normal).

Here's a possible workaround:

• Create two 'Post' MenuButtons, one with the ReturnAuth menuitem, one without it.
• Give the two buttons Names -- e.g. 'mnuPostNoReturn' and 'mnuPostWithReturn'.
• Stack the buttons on top of each other.
• In the form's OnOpen trigger, figure out which button you wish to show, and set the VISIBLE properties accordingly.

  ShowReturn := FigureOutIfReturnShouldShow(COMPANYNAME);
  CurrForm.mnuPostNoReturn.VISIBLE(NOT ShowReturn);
  CurrForm.mnuPostWithReturn.VISIBLE(ShowReturn);

Is that used anywhere in the standard application?

Not that I know of. Nor have I ever used it -- which raises the possibility that this is a 'documentation only' feature -- just because the C/SIDE guide says so doesn't necessarily mean that it works!

It works.

Actually, I just discovered that this does not work if there is a subform on the form and the subform has focus when the menu button is clicked. Results are unpredictible from producing the wrong results to generating errors. A work around is to set the FocusOnClick property for the menu button to Yes.
