I am trying to fill a custom shape with color or a texture, but so far i have no luck. Basically my code look like this:

GraphicsPath graphicsPath = new GraphicsPath();

PointF[] points = new PointF[]
{
new PointF(0, 0),
new PointF(0, 20),
new PointF(20, 20),
new PointF(20, 0),
};
graphicsPath.AddPolygon(points);
//InitTextures();
NCompositeShape shape = new NCompositeShape();
shape.Primitives.AddChild(new NCustomPath(graphicsPath, PathType.OpenFigure));
shape.UpdateModelBounds();
//NImageFillStyle img = new NImageFillStyle(this.textures["bricks"] as Bitmap);
//img.TextureMappingStyle.MapMode = MapMode.RelativeToObject;
//shape.Style.FillStyle = img;
shape.Name = "Basic Wall";
shape.Text = "Basic Wall";


shape.Style.FillStyle = new NColorFillStyle(Color.AliceBlue);
shape.Style.StrokeStyle = new NStrokeStyle(1, Color.FromArgb(0, 0, 0x88));
