The PriorityBindingExpression type exposes the following members.
| Name | Description | |
|---|---|---|
 | 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. (Overrides BindingExpressionBase.HasValidationError.) |
| 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.) |
| Name | Description | |
|---|---|---|
| Equals(Object) | Determines whether the specified object is equal to the current object. (Inherited from Object.) |
| GetHashCode | Serves as a hash function for a particular type. (Inherited from Object.) |
| GetType | Gets the Type of the current instance. (Inherited from Object.) |
| ToString | Returns a string that represents the current object. (Inherited from Object.) |
| UpdateSource | Updates the source on the active binding. (Overrides BindingExpressionBase.UpdateSource().) |
| UpdateTarget | Updates the target on the active binding. (Overrides BindingExpressionBase.UpdateTarget().) |
| 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.) |
| Name | Description | |
|---|---|---|
| IWeakEventListener.ReceiveWeakEvent | This 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.
