Panel.InternalChildren Property
Gets a UIElementCollection of child elements.
Assembly: PresentationFramework (in PresentationFramework.dll)
The returned collection includes items that are added directly in code, and also items that are generated by data binding.
Classes that are derived from Panel should use this property, instead of the Children property, for internal overrides such as MeasureCore and ArrangeCore.
