VisualTreeHelper.FindElementsInHostCoordinates Method (Rect, UIElement)
Retrieves a set of objects that are located within a specified Rect of an object's coordinate space.
Assembly: System.Windows (in System.Windows.dll)
public static IEnumerable<UIElement> FindElementsInHostCoordinates( Rect intersectingRect, UIElement subtree )
- Type: System.Windows.UIElement
The object to search within.
You must specify some object for the subtree value to specify a frame of reference. If you want to use the most general frame of reference available (the entire content area of Windows Phone), use Application.RootVisual as the subtree input.
For this signature, because the determination is done by an area, multiple elements might be returned, and no meaning can be assigned to the order of returned elements in the set.
FindElementsInHostCoordinates is fundamentally similar to the HitTest methods in other frameworks.
