When a page is initally loaded, my column widths are fine and default to that of the longest value. The grid is too wide for the page so I can scroll it horizontally.

If I use the thumb on the scroll bar to move right 'slowly' then the widths are preserved (see attachment 'small scroll to right'). However, if I scroll to the right more aggresively using the scroll bars 'Large Change' value then the width of the columns on the right all seem to expand to match a common denominator that I don't want (see attachment 'large scroll to right').

Is there a property I can set on the grid or columns to stop this automatic resizing? Thanks for your time!
