How can I change the Border color of my control

Override the OnPaint. Here is some code for a derived Button.

[C#]
	public class MyButton : Button
	{
		protected override void OnPaint(PaintEventArgs e)
		{
			base.OnPaint(e);
			int borderWidth = 1;
			Color borderColor = Color.Blue; 
			ControlPaint.DrawBorder(e.Graphics, e.ClipRectangle, borderColor,
					borderWidth, ButtonBorderStyle.Solid, borderColor, borderWidth,
					ButtonBorderStyle.Solid, borderColor, borderWidth, ButtonBorderStyle.Solid,
					borderColor, borderWidth, ButtonBorderStyle.Solid);
		}
	}

[VB.NET]
	Public Class MyButton
		Inherits Button
   
		Protected Overrides Sub OnPaint(e As PaintEventArgs)
			MyBase.OnPaint(e)
			Dim borderWidth As Integer = 1
			Dim borderColor As Color = Color.Blue
			ControlPaint.DrawBorder(e.Graphics, e.ClipRectangle, borderColor, borderWidth, ButtonBorderStyle.Solid, borderColor, borderWidth, ButtonBorderStyle.Solid, borderColor, borderWidth, ButtonBorderStyle.Solid, borderColor, borderWidth, ButtonBorderStyle.Solid)
		End Sub ’OnPaint
	End Class ’MyButton
