Robin,
As per the dataenvironment if you use private datasessions for your forms you should be OK w/o playing with DE properties.

EditGrid class has code in valid ensuring it work arounds grid valid bug (if a control in grid has a validation code and you click outside of grid validation is not done). If you're going to another form while you've hanging validation EditGrid might prevent you from doing that. However there is a flag that enables yuou to that and come back to grid. Check sample form's ReportsTo field textbox code. It disables the validation temporarily, launches a locatorgrid form to get the supervisor and returns it to column.
Hope this was what you're saying :)

Update: If for any reason you need to play with data manually use unload event.
