I am attempting to draw a filled rectangle on the document. 
If I do this the rectangle is filled in            
Code:
 XRect tableHeader = new XRect(20, 250, 550, 15);
            gfx.DrawRectangle(XPens.LightBlue, XBrushes.LightBlue, tableHeader);
If I do this the outline of the rectangle is only shown.   
Code:
         XRect tableHeader = new XRect(20, 250, 550, 15);
            XBrush tableHeaderBackground = new XSolidBrush(new XColor { R = 222, G = 234, B = 246});
            gfx.DrawRectangle(XPens.LightBlue, tableHeaderBackground, tableHeader);
What am I missing here?
TIA
