PriorityBindingExpression Class

Definition

Contains instance information about a single instance of a PriorityBinding.

public ref class PriorityBindingExpression sealed : System::Windows::Data::BindingExpressionBase
public sealed class PriorityBindingExpression : System.Windows.Data.BindingExpressionBase
type PriorityBindingExpression = class
    inherit BindingExpressionBase
Public NotInheritable Class PriorityBindingExpression
Inherits BindingExpressionBase
Inheritance
PriorityBindingExpression

Remarks

PriorityBinding is a single run-time instance of a PriorityBindingExpression. Therefore, it describes a collection of BindingExpression objects that are attached to a single binding target property, which receives its value from the first BindingExpression object in the collection that returns a value successfully. For information about binding expressions, see the Binding and BindingExpression section in the Data Binding Overview.

The binding engine determines which of the BindingExpression objects is the ActiveBindingExpression based on priority. For more information, see PriorityBinding.
