>Is there a way to put a memo field into a grid? I want the grid field to expand dynamically as the user enters info into the field. If this is not possible in the VFP grid class, is there an affordable/flexible grid control that can purchased to add this functionality?

Replace the standard textbox in the grid with an editbox. Just be sure to leave enough vertical space to have room for the editbox's scrollbar, about 3 or so lines high should do it.
