FrameworkElement.DataContextChanged Event

Occurs when this element's data context changes.

Namespace: System.Windows
Assembly: PresentationFramework (in presentationframework.dll)
XML Namespace:  http://schemas.microsoft.com/winfx/2006/xaml/presentation

public event DependencyPropertyChangedEventHandler DataContextChanged
/** @event */
public void add_DataContextChanged (DependencyPropertyChangedEventHandler value)

/** @event */
public void remove_DataContextChanged (DependencyPropertyChangedEventHandler value)

In JScript, you can handle the events defined by a class, but you cannot define your own.
<object DataContextChanged="DependencyPropertyChangedEventHandler" .../>

For an explanation of data contexts and data binding, see Data Binding Overview.

NoteImportant:

When the DataContext for an element changes, all data-bound properties on this element are potentially affected. This applies to any elements that are child elements of the current element in the logical tree, which inherit the data context, and also the current element itself. All such existing bindings must re-interpret the new DataContext and will reevaluate the binding results. The data binding engine is not deterministic about the order of these reevaluations, relative to the raising of the DataContextChanged event. The reevaluations can occur before the event, after the event, or in any mixture.
