Hi Kathy, 

Sure!

Basically, you just need to override this method on your implementation of your IGGridViewDelegate:

public class GriDelegate : IGGridViewDelegate
    {
        public override UIView ResolveSectionColumnView (IGGridView gridView, int section)
        {
            UIView v = new UIView (new RectangleF (0, 0, 0, 100));
            v.BackgroundColor = (section%2==0)? UIColor.Red : UIColor.Green;
            return v;
        }
    }

You'll then just return the view you want to display, based on the section. One thing that you have to specify, is the height of the view. In the above example, the height i'm specifying is 100pts.

And here is the code to setup the grid: 

grid.Delegate = new GriDelegate ();
            IGGridViewDataSourceHelper dsh = new IGGridViewDataSourceHelper ();
            dsh.GroupingKey = "firstName";
            dsh.Data = IGSalesmanItem.GenerateData (100).ToArray ();
            grid.DataSource = dsh;

Hope this helps!
