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
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)
