Gets or sets a value that determines the timing of binding source updates for two-way bindings.
Assembly: System.Windows (in System.Windows.dll)
XMLNS for XAML: Not mapped to an xmlns.
Set this property to Explicit on two-way bindings to disable automatic updates to the binding source. This is useful when you want to perform validation on binding targets before any value changes are copied to the binding source. To update the binding source, use the FrameworkElement.GetBindingExpression method to retrieve a BindingExpression for the target property, and then call the UpdateSource method.
