Hi Fitim,

Thanks for your feedback.

Based on my understanding, you want to draw on the design surface.

Regarding this, we can first get the DesignSurface.View control, then draw
on its child control. Sample code like this:

private void Form1_Load(object sender, EventArgs e)
{
   DesignSurface surface = new DesignSurface();
   surface.BeginLoad(typeof(Form));
   Control view = (Control)surface.View;
   view.Controls[0].Paint += new PaintEventHandler(view_Paint);
   view.Dock = DockStyle.Fill;
   view.Controls[0].BackgroundImage = Image.FromFile("c:\\test.jpg");
   this.Controls.Add(view);
}

void view_Paint(object sender, PaintEventArgs e)
{
   //throw new Exception("The method or operation is not implemented.");
   e.Graphics.DrawLine(new Pen(new SolidBrush(Color.Red)), 0, 0,
this.Width, this.Height);
}

Hope this helps!
