Method Description
EnsureVisualTree ( this view ) : void

Ensures that a visual tree exists for the view.
FindLogicalOrVisualAncestor ( this startElement, Predicate condition, int maxDepth = -1 ) : object

Finds the logical or visual ancestor according to the predicate.
FindParentByPredicate ( this view, Predicate predicate ) : UIView

Finds a parent by predicate. It first tries to find the parent via the UserControl.Parent property, and if that doesn't satisfy, it uses the UserControl.TemplatedParent property.
FindParentByPredicate ( this view, Predicate predicate, int maxDepth ) : UIView

Finds a parent by predicate. It first tries to find the parent via the UserControl.Parent property, and if that doesn't satisfy, it uses the UserControl.TemplatedParent property.
FindParentViewModelContainer ( this view ) : IViewModelContainer

Finds the parent view model container.
FindVisualAncestor ( this startElement, Predicate condition, int maxDepth = -1 ) : object

Finds the visual ancestor according to the predicate.
GetVisualParent ( this element ) : UIView

Gets the logical parent of the specified dependency object.
