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 for routed event that had already been marked as handled by another element along the event route. Adds a specified text string to a ContentControl. Applies an animation to a specified dependency property on this element. Any existing animations are stopped and replaced with the new animation.

Applies an animation to a specified dependency property on this element, with the ability to specify what happens if the property already has a running animation. Builds the current template's visual tree if necessary, and returns a value that indicates whether the visual tree was rebuilt by this call.

Positions child elements and determines a size for a UIElement. Parent elements call this method from their ArrangeCore Rect implementation or a WPF framework-level equivalent to form a recursive layout update. This method constitutes the second pass of a layout update. Starts a specific animation for a specified animated property on this element, with the option of specifying what happens if the property already has a running animation. Begins the sequence of actions contained in the provided storyboard, with options specified for what should happen if the property is already animated.

Begins the sequence of actions contained in the provided storyboard, with specified state for control of the animation after it is started. Attempts to bring the provided region size of this element into view, within any scrollable regions it is contained within. Determines whether the calling thread has access to this DispatcherObject. Clears the local value of a property. The property to be cleared is specified by a DependencyProperty identifier.

Clears the local value of a read-only property. The property to be cleared is specified by a DependencyPropertyKey. Manually closes a Window. Coerces the value of the specified dependency property. This is accomplished by invoking any CoerceValueCallback function specified in property metadata for the dependency property as it exists on the calling DependencyObject. Allows a window to be dragged by a mouse with its left button down over an exposed area of the window's client area.

Determines whether a provided DependencyObject is equivalent to the current DependencyObject. Searches for a resource with the specified key, and throws an exception if the requested resource is not found. Returns the base property value for the specified property on this element, disregarding any possible animated value from a running or stopped animation.

Returns the BindingExpression that represents the binding on the specified property. Gets a hash code for this DependencyObject. Returns a geometry for a clipping mask. The mask applies if the layout system attempts to arrange an element that is larger than the available display space. Creates a specialized enumerator for determining which dependency properties have locally set values on this DependencyObject. Returns the named element in the visual tree of an instantiated ControlTemplate.

Gets the Type of the current instance. Returns the current effective value of a dependency property on this instance of a DependencyObject. Overrides GetVisualChild Int32 , and returns a child at the specified index from a collection of child elements.

Returns a reference to the Window object that hosts the content tree within which the dependency object is located. Returns the input element within the current element that is at the specified coordinates, relative to the current element's origin. Invalidates the arrange state layout for the element. After the invalidation, the element will have its layout updated, which will occur asynchronously unless subsequently forced by UpdateLayout.

Invalidates the rendering of the element, and forces a complete new layout pass. OnRender DrawingContext is called after the layout cycle is completed. Parent elements call this method from their own MeasureCore Size implementations to form a recursive layout update. Calling this method constitutes the first pass the "Measure" pass of a layout update. Implements basic measure-pass layout system behavior for FrameworkElement.
