a Graphical Web

Hi

I want to create a graphical content and then place my controls in that .
but when I Created that I cant see any objects of my site , I see just a graphic .

See here :
---------------

protected System.Web.UI.WebControls.TextBox TextBox1;
protected System.Web.UI.WebControls.Button Button1;
------------
private void Page_Load(object sender, System.EventArgs e)
{

Bitmap B = new Bitmap (800,600,PixelFormat.Format24bppRgb);
Graphics g = Graphics.FromImage(B) ;
g.SmoothingMode = SmoothingMode.AntiAlias ;
Rectangle r = new Rectangle(0,0,800,600) ;
SolidBrush b = new SolidBrush(Color.Black) ;
SolidBrush b2 = new SolidBrush(Color.Orange) ;
g.FillRectangle(b,0,0,800,600) ;

g.FillRectangle(b2,20,20,120,45);
g.FillRectangle(b2,20,120,120,45);
g.FillRectangle(b2,20,220,120,45);

Response.ContentType = "image/jpeg" ;
B.Save(Response.OutputStream,ImageFormat.Jpeg) ;

}
