Example

This example creates a custom corner renderer.

public class MyCornerRenderer : FarPoint.Win.Spread.CellType.CornerRenderer
        {

            {
               // g.FillRectangle(Brushes.Aqua, 0, 0, 30, 30);
                c = Color.Red;
                back = Color.Aqua;
                f = new Font("Arial", 10);
