I need to change the selected cells in a TStringgrid so I want to assign to
the Selection property. The manual (for Tcustomgrid.selection) even tells me
to set this property to achieve this effect, but when I try, I get a
compiler error that "left side cannot be assigned to".

I run Delphi v3.0 Build 5.53.

You didn't show your code, so I can't tell you what's wrong. Here's an
example that works:

  StringGrid1.Selection := TGridRect(Rect(2, 2, 3, 3));

Good luck.

My code was something like this:

    selection.top:=1;

Thanks for your help.
