Methods

Name Description
FindCommonVisualAncestor Finds the common ancestor of two visuals objects If visual is the same object as this, the common ancestor will be the parent
GetRenderTreeId Gets RenderTree's identifier
IsAncestorOf Determines whether the visual object is an ancestor of the descendant visual object This object is not considered to be an ancestor of visual if they are the same
IsConnectedToView Indicates if this visual has been connected to a View
IsDescendantOf Determines whether the visual object is a descendant of the ancestor visual object This object is not considered to be a descendant of visual if they are the same
IsInRenderTree Indicates if a render node has been created in the RenderTree for this visual
IsInvalidated Indicates if this visual is invalidated and should send updates to the render tree
PointFromScreen Converts a Point in screen coordinates into a Point that represents the current coordinate system of the Visual
PointToScreen Converts a Point that represents the current coordinate system of the Visual into a Point in screen coordinates
SetVisualBrushFlag Sets the flag that indicates that this Visual contains a VisualBrush
SubtreeDrawingCommandsChanged Occurs when subtree render commands have changed
TransformToAncestor Returns a transform that can be used to transform coordinates from the Visual to the specified ancestor of the visual object
TransformToDescendant Returns a transform that can be used to transform coordinates from the Visual to the specified visual object descendant
TransformToVisual Returns a transform that can be used to transform coordinates from the Visual to the specified visual object
UpdateRender Pushes all the layout updates into the UI render thread queue to update render nodes

From DependencyObject

Name Description
ClearAnimation Clears the animation value of a property
ClearAnimation Clears the animation value of a property
ClearLocalValue Clears the local value of a property The property to be cleared is specified by a DependencyProperty identifier
CoerceValue Coerces and validates the effective property value
CoerceValue Coerces and validates the effective property value
DependencyPropertyChanged Returns the PropertyChanged event
Destroyed Destroyed delegate is raised when object is going to be destroyed
GetBaseValue Returns the base value without animation nor coerce (this never returns Expression like GetLocalValue)
GetExpression Gets the expression, if any, used to evaluate the specified property value
GetLocalValue Returns the local value of a dependency property, if it exists
GetValue Returns the current effective value of a dependency property on this instance of a DependencyObject
GetValueObject Returns the current effective value of a dependency property on this instance of a DependencyObject as a boxed value
GetValueProvider Gets the provider that returns the effective value for the specified dependency property
HasAnimatedProperties Returns true if there is any animated property
InvalidateProperty Re-evaluates the effective value for the specified dependency property if necessary If null is passed, a full re-evaluation could be needed
IsCached Returns if the value is stored in the cache. If true, the priority is returned in the provider field
IsSealed Gets a value that indicates whether this instance is currently sealed (read-only)
SetAnimation Sets the animated value of a property
SetCurrentValue Sets the current value of a dependency property. The current value is set on the coerce field, without modifying source or animated value
SetCurrentValueObject Sets the current value of a dependency property using a boxed value
SetExpression Sets the expression to be evaluated dynamically to obtain the value of the property
SetValue Sets the local value of a dependency property
SetValueObject Sets the local value (boxed) of a dependency property
