>>I have a menu system that has some choices that are only available if a certain condition exists in a private datasession of a form [e.g., !eof("MainTable")]. However, when the form is instantiated and the table is opened and displayed in a grid, the choice does not activate because the menu is still "looking" at the Default DS instead of the private DS established by the form (according to the VFP3 View window). If I manually switch to the Private DS in the View window, the menu item is now active.

In my Form subclass I have:

if ThisForm.DataSession=2
   Set DataSession to ThisForm.DataSessionID
endif

This code does fire when I run the app (I put a wait window nowait before EndIf). However, the DS "of record" does not change in the VF3 View Window and, consequently, the menu item is still disabled. I manually change to the private DS, and the item enables. Debugging shows the DSID to be 2 and the SET DS TO 2 fires without error but nothing changes.

Any ideas on what I have done wrong?
