Property Value

Type: System.Windows.UIElement
The single child of a Viewbox element. This property has no default value.

If you add an additional child element to a Viewbox it causes an ArgumentException at run time.

The following example shows how to create an instance of a Viewbox and then set its child property by using code.



            // Create a Viewbox and add it to the Canvas
            myViewbox = new Viewbox();
            myViewbox.StretchDirection = StretchDirection.Both;
            myViewbox.Stretch = Stretch.Fill;
            myViewbox.MaxWidth = 400;
            myViewbox.MaxHeight = 400;

            // Create a Grid that will be hosted inside the Viewbox
            myGrid = new Grid();

            // Create an Ellipse that will be hosted inside the Viewbox
            myEllipse = new Ellipse();
            myEllipse.Stroke = Brushes.RoyalBlue;
            myEllipse.Fill = Brushes.LightBlue;

            // Create an TextBlock that will be hosted inside the Viewbox
            myTextBlock = new TextBlock();
            myTextBlock.Text = "Viewbox";

            // Add the children to the Grid
            myGrid.Children.Add(myEllipse);
            myGrid.Children.Add(myTextBlock);


            // Add the Grid as the single child of the Viewbox
            myViewbox.Child = myGrid;


            // Position the Viewbox in the Parent Canvas
            Canvas.SetTop(myViewbox, 100);
            Canvas.SetLeft(myViewbox, 100);
            myCanvas.Children.Add(myViewbox);
