Insanely simple GradientPanel for WinForms

This has probably been done a hundred times already, but I couldn't find one in the first few pages of google results, so I wrote my own in ~40 lines of C#:

using System;
using System.ComponentModel;
using System.Drawing;
using System.Drawing.Drawing2D;
using System.Windows.Forms;

namespace PostXING.Controls
{
	/// <summary>
	/// GradientPanel is just like a regular panel except it optionally  
	/// shows a gradient.
	/// </summary>
	[ToolboxBitmap(typeof(Panel))]
	public class GradientPanel : Panel
	{
		/// <summary>
		/// Property GradientColor (Color)
		/// </summary>
		private Color _gradientColor;
		public Color GradientColor {
			get { return this._gradientColor;}
			set { this._gradientColor = value;}
		}

		/// <summary>
		/// Property Rotation (float)
		/// </summary>
		private float _rotation;
		public float Rotation {
			get { return this._rotation;}
			set { this._rotation = value;}
		}

		protected override void OnPaint(PaintEventArgs e) {
                        if(e.ClipRectangle.IsEmpty) return; //why draw if non-visible?
 

			using(LinearGradientBrush lgb = new 
                           LinearGradientBrush(this.ClientRectangle, 
		              this.BackColor, 
		              this.GradientColor, 
		              this.Rotation)){
				e.Graphics.FillRectangle(lgb, this.ClientRectangle);
			}

                        base.OnPaint (e); //right, want anything handled to be drawn too.

		}
	}
}

There it is. Enjoy!
