Methods

The Control class has these methods. It also inherits methods from the Object class.

Method	Description
AddHandler	Adds a routed event handler for a specified routed event, adding the handler to the handler collection on the current element. Specify handledEventsToo as true to have the provided handler be invoked even if the event is handled elsewhere. (Inherited from UIElement)
ApplyTemplate	Loads the relevant control template so that its parts can be referenced.
Arrange	Positions child objects and determines a size for a UIElement. Parent objects that implement custom layout for their child elements should call this method from their layout override implementations to form a recursive layout update. (Inherited from UIElement)
ArrangeOverride	Provides the behavior for the Arrange pass of layout. Classes can override this method to define their own Arrange pass behavior. (Inherited from FrameworkElement)
CapturePointer	Sets pointer capture to a UIElement. Once captured, only the element that has capture will fire pointer-related events. (Inherited from UIElement)
ClearValue	Clears the local value of a dependency property. (Inherited from DependencyObject)
FindName	Retrieves an object that has the specified identifier name. (Inherited from FrameworkElement)
FindSubElementsForTouchTargeting	Enables a UIElement subclass to expose child elements that assist with resolving touch targeting. (Inherited from UIElement)
Focus	Attempts to set the focus on the control.
GetAnimationBaseValue	Returns any base value established for a dependency property, which would apply in cases where an animation is not active. (Inherited from DependencyObject)
GetTemplateChild	Retrieves the named element in the instantiated ControlTemplate visual tree.
GetValue	Returns the current effective value of a dependency property from a DependencyObject. (Inherited from DependencyObject)
InvalidateArrange	Invalidates the arrange state (layout) for a UIElement. After the invalidation, the UIElement will have its layout updated, which will occur asynchronously. (Inherited from UIElement)
InvalidateMeasure	Invalidates the measurement state (layout) for a UIElement. (Inherited from UIElement)
Measure	Updates the DesiredSize of a UIElement. Typically, objects that implement custom layout for their layout children call this method from their own MeasureOverride implementations to form a recursive layout update. (Inherited from UIElement)
MeasureOverride	Provides the behavior for the Measure pass of the layout cycle. Classes can override this method to define their own Measure pass behavior. (Inherited from FrameworkElement)
OnApplyTemplate	Invoked whenever application code or internal processes (such as a rebuilding layout pass) call ApplyTemplate. In simplest terms, this means the method is called just before a UI element displays in your app. Override this method to influence the default post-template logic of a class. (Inherited from FrameworkElement)
OnCreateAutomationPeer	When implemented in a derived class, returns class-specific AutomationPeer implementations for the Microsoft UI Automation infrastructure. (Inherited from UIElement)
OnDisconnectVisualChildren	Override this method to implement how layout and logic should behave when items are removed from a class-specific content or children property. (Inherited from UIElement)
OnDoubleTapped	Called before the DoubleTapped event occurs.
OnDragEnter	Called before the DragEnter event occurs.
OnDragLeave	Called before the DragLeave event occurs.
OnDragOver	Called before the DragOver event occurs.
OnDrop	Called before the Drop event occurs.
OnGotFocus	Called before the GotFocus event occurs.
OnHolding	Called before the Holding event occurs.
OnKeyDown	Called before the KeyDown event occurs.
OnKeyUp	Called before the KeyUp event occurs.
OnLostFocus	Called before the LostFocus event occurs.
OnManipulationCompleted	Called before the ManipulationCompleted event occurs.
OnManipulationDelta	Called before the ManipulationDelta event occurs.
OnManipulationInertiaStarting	Called before the ManipulationInertiaStarting event occurs.
OnManipulationStarted	Called before the ManipulationStarted event occurs.
OnManipulationStarting	Called before the ManipulationStarting event occurs.
OnPointerCanceled	Called before the PointerCanceled event occurs.
OnPointerCaptureLost	Called before the PointerCaptureLost event occurs.
OnPointerEntered	Called before the PointerEntered event occurs.
OnPointerExited	Called before the PointerExited event occurs.
OnPointerMoved	Called before the PointerMoved event occurs.
OnPointerPressed	Called before the PointerPressed event occurs.
OnPointerReleased	Called before the PointerReleased event occurs.
OnPointerWheelChanged	Called before the PointerWheelChanged event occurs.
OnRightTapped	Called before the RightTapped event occurs.
OnTapped	Called before the Tapped event occurs.
ReadLocalValue	Returns the local value of a dependency property, if a local value is set. (Inherited from DependencyObject)
ReleasePointerCapture	Releases pointer captures for capture of one specific pointer by this UIElement. (Inherited from UIElement)
ReleasePointerCaptures	Releases all pointer captures held by this element. (Inherited from UIElement)
RemoveHandler	Removes the specified routed event handler from this UIElement. Typically the handler in question was added by AddHandler. (Inherited from UIElement)
SetBinding	Attaches a binding to a FrameworkElement, using the provided binding object. (Inherited from FrameworkElement)
SetValue	Sets the local value of a dependency property on a DependencyObject. (Inherited from DependencyObject)
TransformToVisual	Returns a transform object that can be used to transform coordinates from the UIElement to the specified object. (Inherited from UIElement)
UpdateLayout	Ensures that all positions of child objects of a UIElement are properly updated for layout. (Inherited from UIElement)
