I think David gave you the probable answer, but it might be interesting to know the 'why'...
I **think** that once you change any form's (or control's??) dimensions from "default" then the Resize runs at STARTUP too. Probably before your oldxxx values have been set.

It was all resizing fine until I changed the width value in designer on the grid (wanted to startout with a smaller size when the form is instantiated). Does changing the width of a grid change some other property I'm not aware of?

>>>However, I would like to add additional functionality. I would like to add the ability for the user to widen (expand) the treeview control if desired (to view all branches left to right) and have the width of the grid narrow respectively just like the windows explorer window (dragging the separator bar left or right widens/narrows each window respectively). Is there anyway to do this? Is there some other control that does this and has the same functionality of what I'm doing with the treeview and grid?
