Wpf itemscontrol binding not updating
A Command Binding enables command handling for this element, and declares the linkage between a command, its events, and the handlers attached by this element.(Inherited from UIElement.)Gets or sets a property that enables customization of appearance, effects, or other style characteristics that will apply to this element when it captures keyboard focus.(Inherited from Framework Element.)Gets or sets a value that declares whether this element can possibly be returned as a hit test result from some portion of its rendered content.This is a dependency property.(Inherited from UIElement.)Gets a value that indicates whether this element has been initialized, either during processing by a XAML processor, or by explicitly having its End Init method called.
Parent elements call this method from their Arrange Core implementation (or a WPF framework-level equivalent) to form a recursive layout update.
This is accomplished by invoking any Coerce Value Callback function specified in property metadata for the dependency property as it exists on the calling Dependency Object.(Inherited from Dependency Object.)Invalidates the arrange state (layout) for the element.
