Applying Custom Renderer to the Clock Control in Windows Forms Clock

Customization of rendering by overriding the method

Clock control enables you to customize the Clock control by applying the custom renderer.

CustomRenderer renderer = new CustomRenderer();
this.clock1.Renderer = renderer;
public class CustomRenderer : ClockRenderer
{
    public override void DrawInterior(Graphics g, float thickness, PointF startPoint, PointF endPoint, Color color, string sender)
    {
        if (sender == "SecondsHand")
        {
            g.SmoothingMode = SmoothingMode.AntiAlias;
            Pen p = new Pen(color, thickness + thickness);
            p.StartCap = LineCap.SquareAnchor;
            p.EndCap = LineCap.ArrowAnchor;
            g.DrawLine(p, startPoint, endPoint);
            p.Dispose();
        }
        else if (sender == "MinutesHand")
        {
            g.SmoothingMode = SmoothingMode.AntiAlias;
            Pen p = new Pen(color, thickness + thickness);
            p.StartCap = LineCap.SquareAnchor;
            p.EndCap = LineCap.ArrowAnchor;
            g.DrawLine(p, startPoint, endPoint);
            p.Dispose();
        }
        else if (sender == "HoursHand")
