Example

This example creates a custom corner renderer.

public class MyCornerRenderer : FarPoint.Win.Spread.CellType.IRenderer
        {
public bool CanOverflow() { return true; }
            public bool CanBeOverflown() { return true; }
            public virtual void PaintCell(Graphics g, Rectangle r, FarPoint.Win.Spread.Appearance appear, object value, bool issel, bool isl, float zoom) {
                g.FillRectangle(Brushes.Green, 0, 0, 30, 30);                
            }
            public Size GetPreferredSize(Graphics g, Size size, FarPoint.Win.Spread.Appearance appear, object value, float zoomFactor)
            {
                size = new Size(10, 10);
                return size;
            }            
        }

        private void Form1_Load(object sender, EventArgs e)
        {      
            fpSpread1.ActiveSheet.SheetCornerStyle.Renderer = new MyCornerRenderer();       
        }
