using (Pen pen = new Pen(Color.Red, 2))<br/>
{<br/>
e.Graphics.DrawRectangle(pen, Rect);<br/>
}<br/>
}<br/>
}<br/>
}

So i thought inside the pictruebox1 paint event ot register the picturebox2 paint event: pictureBox2.Paint += new PaintEventHandler(pictureBox2_Paint);<br/>
So when its painting in picturebox1 it will active the paint event on picturebox2.
And then in the end of the code i created the picturebox2 paint vent:

private void pictureBox2_Paint(object sender, PaintEventArgs e)<br/>
{<br/>
using (Pen pen = new Pen(Color.Red, 2))<br/>
{<br/>
e.Graphics.DrawRectangle(pen, Rect);<br/>
}<br/>
}
But i used a breakpoint on where i register the picturebox2 paint event and it stoped there.
But when i put breakpoint on the picturebox2 paint event i created its never get there never stop.
What did i do wrong?

Thanks. <hr class="sig danieli
