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.

Properties

ActiveBindingExpression	Gets the active BindingExpression object.
BindingExpressions	Gets the collection of BindingExpression objects inside this instance of PriorityBindingExpression.
BindingGroup	Gets the BindingGroup that this binding expression belongs to. (Inherited from BindingExpressionBase)
HasError	Gets a value that indicates whether the parent binding has a failed validation rule. (Inherited from BindingExpressionBase)
HasValidationError	Gets a value that indicates whether the parent binding has a failed validation rule.
HasValidationError	Gets a value that indicates whether the parent binding has a failed validation rule. (Inherited from BindingExpressionBase)
IsDirty	Gets 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)
ParentBindingBase	Gets the BindingBase object from which this BindingExpressionBase object is created. (Inherited from BindingExpressionBase)
ParentPriorityBinding	Gets the PriorityBinding object from which this PriorityBindingExpression is created.
Status	Gets the status of the binding expression. (Inherited from BindingExpressionBase)
Target	Gets the element that is the binding target object of this binding expression. (Inherited from BindingExpressionBase)
TargetProperty	Gets the binding target property of this binding expression. (Inherited from BindingExpressionBase)
ValidationError	Gets the ValidationError that caused this instance of BindingExpressionBase to be invalid. (Inherited from BindingExpressionBase)
ValidationErrors	Gets a collection of ValidationError objects that caused this instance of BindingExpressionBase to be invalid. (Inherited from BindingExpressionBase)

Methods

Equals(Object)	Determines whether the specified object is equal to the current object. (Inherited from Object)
GetHashCode()	Serves as the default hash function. (Inherited from Object)
GetType()	Gets the Type of the current instance. (Inherited from Object)
MemberwiseClone()	Creates a shallow copy of the current Object. (Inherited from Object)
ToString()	Returns a string that represents the current object. (Inherited from Object)
UpdateSource()	Updates the source on the active binding.
UpdateSource()	Sends the current binding target value to the binding source in TwoWay or OneWayToSource bindings. (Inherited from BindingExpressionBase)
UpdateTarget()	Updates the target on the active binding.
UpdateTarget()	Forces a data transfer from the binding source to the binding target. (Inherited from BindingExpressionBase)
ValidateWithoutUpdate()	Runs 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)
