protected virtual int Visual3DChildrenCount { get; }

Property Value

Type: System.Int32
The number of child elements.

By default, a Visual3D has no child elements. Therefore, the default implementation always returns 0.

The Visual3DChildrenCount property is introduced in .NET Framework version 3.5. For more information, see .NET Framework Versions and Dependencies.

Notes to Inheritors

To correctly enumerate the visual tree, a class that derives from Visual3D must override this property and also override the GetVisual3DChild method.
