The following example shows how to draw text to a DrawingVisual using a DrawingContext object. A drawing context is returned by calling the RenderOpen method of a DrawingVisual object. You can draw graphics and text into a drawing context.

To draw text into the drawing context, use the DrawText method of a DrawingContext object. When you are finished drawing content into the drawing context, call the Close method to close the drawing context and persist the content.

		' Create a DrawingVisual that contains text.
		Private Function CreateDrawingVisualText() As DrawingVisual
			' Create an instance of a DrawingVisual.
			Dim drawingVisual As New DrawingVisual()

			' Retrieve the DrawingContext from the DrawingVisual.
			Dim drawingContext As DrawingContext = drawingVisual.RenderOpen()

			' Draw a formatted text string into the DrawingContext.
			drawingContext.DrawText(New FormattedText("Click Me!", CultureInfo.GetCultureInfo("en-us"), FlowDirection.LeftToRight, New Typeface("Verdana"), 36, Brushes.Black), New Point(200, 116))

			' Close the DrawingContext to persist changes to the DrawingVisual.
			drawingContext.Close()

			Return drawingVisual
		End Function
