could you describe the problem you face with it. At first glance the "button1_MouseUp" must look like this:



// button = new button1(Right); //oh omit this

if (e.Button == MouseUp.Right)

{ //here



pictureBox1.BackColor = Color.DarkMagenta;



pictureBox1.Invalidate();

} //and here



else

{ // and also here

e.Graphics.FillEllipse = Color.DarkMagenta;

Invalidate(); //and also here

}//also here
