    Hi Manoj,


    The graphics object in Wpf is different than Winforms since Wpf uses Vector Graphics. In Wpf you will be using a DrawingVisual, DrawingContext, FormattedText and a BitmapImage, the DrawingContext is equivalent to the Graphics object in Winforms. This is a quick example to show what I mean.

    public MainWindow()

    {

        InitializeComponent();

        Grid myGrid = new Grid();

        BitmapImage bmp = new BitmapImage(new Uri(@"C:\temp\test.jpg")); //Use the path to your Image

        DrawingVisual dv = new DrawingVisual();

        DrawingContext dc = dv.RenderOpen();

        dc.DrawImage(bmp, new Rect(100, 100, 300, 300));

        dc.DrawText(new FormattedText("Hello World",

                    CultureInfo.GetCultureInfo("en-us"),

                    FlowDirection.LeftToRight,

                    new Typeface("Arial"),

                    30, System.Windows.Media.Brushes.Black),

                    new System.Windows.Point(100, 120));

        dc.Close();

        myGrid.Background = new VisualBrush(dv);

        this.Content = myGrid;

    }
