ScanOverlay Methods

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.

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.

Provides the behavior for the Arrange pass of layout. Classes can override this method to define their own Arrange pass behavior.

Cancels ongoing direct manipulation processing (system-defined panning/zooming) on any ScrollViewer parent that contains the current UIElement.

Sets pointer capture to a UIElement. Once captured, only the element that has capture will fire pointer-related events.

Clears the local value of a dependency property.

Determines whether the specified object is equal to the current object.

Allows an object to try to free resources and perform other cleanup operations before it is reclaimed by garbage collection.

Retrieves an object that has the specified identifier name.

Enables a UIElement subclass to expose child elements that assist with resolving touch targeting.

Returns any base value established for a dependency property, which would apply in cases where an animation is not active.

Returns the BindingExpression that represents the binding on the specified property.

Serves as the default hash function.

Gets the Type of the current instance.

Returns the current effective value of a dependency property from a DependencyObject.

When implemented in a derived class, enables per-state construction of a visual tree for a control template in code, rather than by loading XAML for all states at control startup.

Invalidates the arrange state (layout) for a UIElement. After the invalidation, the UIElement will have its layout updated, which will occur asynchronously.

Invalidates the measurement state (layout) for a UIElement.

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.

Provides the behavior for the Measure pass of the layout cycle. Classes can override this method to define their own Measure pass behavior.

Creates a shallow copy of the current Object.

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.

When implemented in a derived class, returns class-specific AutomationPeer implementations for the Microsoft UI Automation infrastructure.

Override this method to implement how layout and logic should behave when items are removed from a class-specific content or children property.

Returns the local value of a dependency property, if a local value is set.

Releases pointer captures for capture of one specific pointer by this UIElement.

Releases all pointer captures held by this element.

Removes the specified routed event handler from this UIElement. Typically the handler in question was added by AddHandler.

Attaches a binding to a FrameworkElement, using the provided binding object.

Sets the local value of a dependency property on a DependencyObject.

Returns a string that represents the current object.

Returns a transform object that can be used to transform coordinates from the UIElement to the specified object.

Ensures that all positions of child objects of a UIElement are properly updated for layout.
