Gets a value that indicates whether this element has been loaded for presentation.
Assembly: PresentationFramework (in PresentationFramework.dll)
From a newly constructed FrameworkElement, this property starts off false, and remains true after it is set to true, even if the element is subsequently removed from a connected logical tree by code. true state is set by the general presentation logic when elements are loaded into the presentation engine.
The following example implements two handlers: one is handling the Loaded event of the root element, so it is certain that the page root element is loaded because that is the significance of the event. The other handler is hooked to a user control, and calls to assure that the root element is loaded completely. Both handlers call the same function (not shown) that will populate child elements with fresh data.
