PriorityBindingExpression Class

Contains instance information about a single instance of a PriorityBinding.


Namespace:  System.Windows.Data
Assembly:  PresentationFramework (in PresentationFramework.dll)

public sealed class PriorityBindingExpression : BindingExpressionBase

The PriorityBindingExpression type exposes the following members.

Public propertyActiveBindingExpressionGets the active BindingExpression object.
Public propertyBindingExpressionsGets the collection of BindingExpression objects inside this instance of PriorityBindingExpression.
Public propertyBindingGroupGets the BindingGroup that this binding expression belongs to. (Inherited from BindingExpressionBase.)
Public propertyHasErrorGets a value that indicates whether the parent binding has a failed validation rule. (Inherited from BindingExpressionBase.)
Public propertyHasValidationErrorGets a value that indicates whether the parent binding has a failed validation rule. (Overrides BindingExpressionBase.HasValidationError.)
Public propertyIsDirtyGets or sets a value that indicates whether the target of the binding has a value that has not been written to the source. (Inherited from BindingExpressionBase.)
Public propertyParentBindingBaseGets the BindingBase object from which this BindingExpressionBase object is created. (Inherited from BindingExpressionBase.)
Public propertyParentPriorityBindingGets the PriorityBinding object from which this PriorityBindingExpression is created.
Public propertyStatusGets the status of the binding expression. (Inherited from BindingExpressionBase.)
Public propertyTargetGets the element that is the binding target object of this binding expression. (Inherited from BindingExpressionBase.)
Public propertyTargetPropertyGets the binding target property of this binding expression. (Inherited from BindingExpressionBase.)
Public propertyValidationErrorGets the ValidationError that caused this instance of BindingExpressionBase to be invalid. (Inherited from BindingExpressionBase.)
Public propertyValidationErrorsGets a collection of ValidationError objects that caused this instance of BindingExpressionBase to be invalid. (Inherited from BindingExpressionBase.)

Public methodEquals(Object)Determines whether the specified object is equal to the current object. (Inherited from Object.)
Public methodGetHashCodeServes as the default hash function. (Inherited from Object.)
Public methodGetTypeGets the Type of the current instance. (Inherited from Object.)
Public methodToStringReturns a string that represents the current object. (Inherited from Object.)
Public methodUpdateSourceUpdates the source on the active binding. (Overrides BindingExpressionBase.UpdateSource().)
Public methodUpdateTargetUpdates the target on the active binding. (Overrides BindingExpressionBase.UpdateTarget().)
Public methodValidateWithoutUpdateRuns any ValidationRule objects on the associated Binding that have the ValidationStep property set to RawProposedValue or ConvertedProposedValue. This method does not update the source. (Inherited from BindingExpressionBase.)

Explicit interface implemetationPrivate methodIWeakEventListener.ReceiveWeakEventThis member supports the Windows Presentation Foundation (WPF) infrastructure and is not intended to be used directly from your code. (Inherited from BindingExpressionBase.)

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.
