Gary,

Tks. Learning more every day!

>Jumping in here,
>I use listboxes exclusively instead of grids now in the client server framework I use. I put it in a container that has textboxes over the listbox for editing. As a user up and down arrows, the textbox values change to reflect this and it allows row by row record adding, delete and updating of the back end. Code in the textbox class allows me to resort the listbox by the active column and resizing the columns should be easy, thought I've never tried. There is a fair amount of code in the background, but it's extremely fast, so the users don't notice anything.
