You may add Editbox to your form and have:
Thisform.Myeditbox.value=mytable.mymemofield
in grid.afterrowcolchange event. Surely, you may provide user with a tool (button) to make editbox visible/invisible.
Again,, I would recommend you to put memo content to grid.column.textbox, so user will always see, let say, 20 first chars, and get others by toggling Editbox.Visible property.
