Method	Description
CreateImageBrushFromVisual ( FrameworkElement element ) : System.Windows.Media.Imaging.RenderTargetBitmap	Helper method to create a snapshot of a visual item as a bitmap image. Typically used for things like drag and drop or any time we want to do something where we don't want the hit of a video running in an animating object
FindDownInTree ( Visual parent, IFinderMatchVisualHelper helper ) : List	Walker that looks down in the visual tree for any matching elements, typically used with Type
FindDownInTree ( List lst, DependencyObject parent, DependencyObject ignore, IFinderMatchVisualHelper helper ) : void	Really a helper for FindDownInTree, typically not called directly.
FindElementOfType ( Visual parent, Type ty ) : FrameworkElement	Simple form call that returns the first element of a given type down in the visual tree
FindElementOfTypeUp ( Visual parent, Type ty ) : FrameworkElement	Simple form call that returns the first element of a given type up in the visual tree
FindElementsOfType ( Visual parent, Type ty ) : List	Simple form call that returns all elements of a given type down in the visual tree
FindFocusedElement ( Visual parent ) : FrameworkElement	Helper to find the currently focused element
FindInTree ( Visual parent, IFinderMatchVisualHelper helper ) : List	Walker that looks both UP and down in the visual tree for any matching elements, typically used with Type
FindItemsHost ( Visual parent ) : FrameworkElement	Helper to find a items host (e.g. in a listbox etc) down in the tree
FindUpInTree ( List lst, Visual parent, Visual ignore, IFinderMatchVisualHelper helper ) : void	Really a helper to look Up in a tree, typically not called directly.
FindVisualElement ( Visual parent, String ElementName ) : FrameworkElement	Helper to find the given named element down in the visual tree
FindVisualElementUp ( Visual parent, String ElementName ) : FrameworkElement	Helper to find the given named element up in the visual tree
SingleFindDownInTree ( Visual parent, IFinderMatchVisualHelper helper ) : FrameworkElement	Typically used method that walks down the visual tree from a given point to locate a given match only once. Typically used with Name/ItemHost etc type matching. Only returns one element
SingleFindInTree ( Visual parent, IFinderMatchVisualHelper helper ) : FrameworkElement	All way visual tree helper that searches UP and DOWN in a tree for the matching pattern. This is used to walk for name matches or type matches typically. Returns only the first matching element
TurnOffMediaElements ( Visual parent ) : void	Helper to pause any media elements down in the visual tree
TurnOnMediaElements ( Visual parent ) : void	Helper to resume playing any media elements down in the visual tree
