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
Dim myViewbox As New Viewbox()
myViewbox.StretchDirection = StretchDirection.Both
myViewbox.Stretch = Stretch.Fill
myViewbox.MaxWidth = 400
myViewbox.MaxHeight = 400

' Create a new Grid that is hosted in the Viewbox
Dim myGrid As New Grid()

' Create an Ellipse that is also hosted in the Grid
Dim myEllipse As New Ellipse()
myEllipse.Stroke = Brushes.RoyalBlue
myEllipse.Fill = Brushes.LightBlue

' Create a TextBlock that is also hosted in the Grid
Dim myTextBlock As 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)
