Question : Access subform - grow as nececssary to show all rows

Hello all;

I have a form with several subforms. Each subform is a grid style subform (that is, a header with column headings, and rows for each record.) What I want to do but cannot figure out how is make each subform grow as necessary to display all records for that subform.

Each subform may have only a single record, up to 10+ (maybe more in some cases.) I want the parent form then to grow as necessary also to display all subforms, and each of their rows. In some cases the parent form may be small enough to fit on a single screen, in other cases (cases with subforms that have 10+ records each), the parent form would be very long and would have a scroll bar.

The problem is that the 'Can Grow' and 'Can Shrink' properties only apply to reports/printing, not the actual subform when in edit mode.

Obviously, I could just put scroll bars on each subform, but that would be ugly and clunky.

Can anyone help? Thanks!

Hi UptimeSystems

Try the attached code in your Form_Current procedure. You might have to tweak it slightly, but it should give you the general idea.

You'll probably want to add some error handling too :-)
