Contains instance information about a single instance of a MultiBinding.

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

public sealed class MultiBindingExpression : BindingExpressionBase

The MultiBindingExpression type exposes the following members.

  NameDescription
Public propertyBindingExpressionsGets the collection of BindingExpression objects in this instance of MultiBindingExpression.
Public propertyBindingGroupGets the BindingGroup that this binding expression belongs to. (Inherited from BindingExpressionBase.)
Public propertyHasErrorReturns a value that indicates whether any of the inner Binding objects or the MultiBinding itself has a failing validation rule. (Overrides BindingExpressionBase.HasError.)
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 propertyParentMultiBindingGets the MultiBinding object from which this MultiBindingExpression 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 object that caused this instance of MultiBindingExpression to be invalid. (Overrides BindingExpressionBase.ValidationError.)
Public propertyValidationErrorsGets a collection of ValidationError objects that caused this instance of BindingExpressionBase to be invalid. (Inherited from BindingExpressionBase.)

  NameDescription
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 methodUpdateSourceSends the current binding target value to the binding source properties in TwoWay or OneWayToSource bindings. (Overrides BindingExpressionBase.UpdateSource().)
Public methodUpdateTargetForces a data transfer from the binding source properties to the binding target property. (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.)

MultiBindingExpression describes a single run-time instance of a MultiBinding. Therefore, it describes a collection of BindingExpression objects attached to a single binding target property.

For information about binding expressions, see the Binding and BindingExpression section in the Data Binding Overview.

With the use of a converter, the property values of the BindingExpression objects in a MultiBindingExpression produce a final value for the target property. In the reverse direction, the target property value is translated to a set of values that are fed back into the BindingExpression objects. For more information, see MultiBinding.
