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

// 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);
