C# Class Microsoft.Silverlight.Testing.Controls.VisualTreeExtensions

Provides useful extensions for working with the visual tree.

Since many of these extension methods are declared on types like DependencyObject high up in the class hierarchy, we've placed them in the Primitives namespace which is less likely to be imported for normal scenarios.

Private Methods

Method	Description
GetLogicalChildren ( this parent ) : IEnumerable	Retrieves all the logical children of a framework element using a breadth-first search. For performance reasons this method manually manages the stack instead of using recursion.
GetLogicalDescendents ( this parent ) : IEnumerable	Retrieves all the logical descendents of a framework element using a breadth-first search. For performance reasons this method manually manages the stack instead of using recursion.
GetVisualAncestorsAndSelfIterator ( DependencyObject element ) : IEnumerable	Get the visual tree ancestors of an element and the element itself.
GetVisualChildrenAndSelfIterator ( this element ) : IEnumerable	Get the visual tree children of an element and the element itself.
GetVisualDescendantsAndSelfIterator ( DependencyObject element ) : IEnumerable	Get the visual tree descendants of an element and the element itself.
