[C#] Subclassing ToolStrip + Overriding OnPaint Event

[Nazgulled]

I have subclassed the ToolStrip and ToolStripProfessionalRenderer to make a toolbar work much like of Thunderbird's (version 2) options dialog. I have that goal accomplished but I have a little issue...

 

I also tried to override the OnPaint event of ToolStrip so I could 2 little lines just below the ToolStrip, but for some reason, it's producing unexpected results. The first 2 buttons in the ToolStrip also have parts of those lines painted above them and I can't see why that's happening. The strange thing is, it only happens on the first 2 buttons (I tried to delete them and re add them, but it didn't work).

 

Below, there's a screenshot and the code:

using System;
using System.Collections.Generic;
using System.Text;
using System.Drawing;
using System.Windows.Forms;

namespace FireNotes
{
internal class MyToolStrip : ToolStrip
{
	protected override void OnPaint(PaintEventArgs e)
	{
		base.OnPaint(e);

		Pen cDarkDark = new Pen(SystemColors.ControlDarkDark);
		Pen cLightLight = new Pen(SystemColors.ControlLightLight);

		e.Graphics.DrawLine(cDarkDark, 0, e.ClipRectangle.Height - 2, e.ClipRectangle.Width + 1, e.ClipRectangle.Height - 2);
		e.Graphics.DrawLine(cLightLight, 0, e.ClipRectangle.Height - 1, e.ClipRectangle.Width + 1, e.ClipRectangle.Height - 1);
	}

	protected override void OnItemClicked(ToolStripItemClickedEventArgs e)
	{
		SwapSelectedButton((ToolStripButton)e.ClickedItem);
		base.OnItemClicked(e);
	}
	
	private void SwapSelectedButton(ToolStripButton tsbSelected) {
		ToolStripButton tsbThis;

		foreach (ToolStripItem tsItem in base.Items) {
			tsbThis = tsItem as ToolStripButton;

			if (tsbThis != tsbSelected) {
				tsbThis.Checked = false;
			} else {
				tsbThis.Checked = true;
			}
		}
	}
}

internal class MyToolStripProfessionalRenderer : ToolStripProfessionalRenderer
{
	protected override void OnRenderButtonBackground(ToolStripItemRenderEventArgs e)
	{
		ToolStripButton tsbItem = e.Item as ToolStripButton;
		Rectangle rect = new Rectangle(0, 0, 70, 43);

		if (tsbItem.Checked || (tsbItem.Selected && tsbItem.Checked)) {
			tsbItem.ForeColor = Color.White;
			e.Graphics.DrawImage(Properties.Resources.TSButton_State2, rect);
		} else if (tsbItem.Selected) {
			tsbItem.ForeColor = Color.White;
			e.Graphics.DrawImage(Properties.Resources.TSButton_State1, rect);
		}
	}
}
}

Can't nobody help me out? Edited July 11, 2007 by Nazgulled

Nevermind!

 

The problem was on e.ClipRectangle.Height/e.ClipRectangle.Width and I just replaced it by base.Height/base.Width and I also changed to the OnBackgroundPaint as it makes more sense.
