>Is there a quick way to find if a column is viewable in the grid? Will I need to use the LeftColumn property and add collumn widths to compare with the width of the grid to find this? Does anyone know an easier way?

I had to do it just as you describe. I built grid in a grid where the user can drag from one column in one grid to another column in another grid and I had to do the coordinate comparisons.
