Visual.AddVisualChild Method (Visual)
Defines the parent-child relationship between two visuals.
Assembly: PresentationCore (in PresentationCore.dll)
The VisualCollection can be used as a default implementation for storing child objects.method sets up the parent-child relationship between two visual objects. This method must be used when you need greater low-level control over the underlying storage implementation of visual child objects.
The following example shows how to define custom storage requirements for a visual child. The example uses the RemoveVisualChild methods to sets up the parent-child relationship between the parent visual and child. In order for the visual tree to be enumerated correctly, the example provides overridden implementations of the GetVisualChild method and VisualChildrenCount property.and
Although it is possible to use VisualCollection to create parent-child relationships between visual objects, it is more efficient to provide your own custom storage implementation when only one child is linked to a parent.
