MultiDataTrigger Class

namespace Noesis | MSDN

Represents a trigger that applies property values or performs actions when the bound data meets a set of conditions.

A MultiDataTrigger object is similar to a MultiTrigger, except that the conditions of a MultiDataTrigger are based on property values of bound data instead of those of a UIElement. In a MultiDataTrigger, a condition is met when the property value of the data item matches the specified Value. You can then use setters or the EnterActions and ExitActions properties to apply changes or start actions when all of the conditions are met.

Properties

Name Description
 Conditions Gets a collection of Condition objects. Changes to property values are applied when all of the conditions in the collection are met.
 Setters Gets a collection of Setter objects, which describe the property values to apply when all of the conditions of the MultiTrigger are met.

From BaseTrigger

Name Description
 EnterActions Gets a collection of TriggerAction objects to apply when the trigger object becomes active. This property does not apply to the EventTrigger class
 ExitActions Gets a collection of TriggerAction objects to apply when the trigger object becomes inactive. This property does not apply to the EventTrigger class

 Dependency Property    Reflection Property

From DispatcherObject

Name Description
 ThreadId Gets the thread this DispatcherObject is associated with. Returns NoThreadId when this object is not attached to any thread.

Methods

From DependencyObject

Name Description
 ClearAnimation(dp) Clears the animation value of a property
 ClearLocalValue(dp) Clears the local value of a property The property to be cleared is specified by a DependencyProperty identifier
 CoerceValue(dp) Coerces and validates the effective property value
 DependencyPropertyChanged() Returns the PropertyChanged event
 Destroyed() Destroyed delegate is raised when object is going to be destroyed
 GetBaseValue(dp) Returns the base value without animation nor coerce (this never returns Expression like GetLocalValue)
 GetExpression(dp) Gets the expression, if any, used to evaluate the specified property value
 GetLocalValue(dp) Returns the local value of a dependency property, if it exists
 GetValue(dp) Returns the current effective value of a dependency property on this instance of a DependencyObject
 GetValueObject(dp) Returns the current effective value of a dependency property on this instance of a DependencyObject as a boxed value
 GetValueProvider(dp) Gets the provider that returns the effective value for the specified dependency property
 HasAnimatedProperties() Returns true if there is any animated property
 InvalidateProperty(dp, priority) Re-evaluates the effective value for the specified dependency property if necessary If null is passed, a full re-evaluation could be needed
 IsCached(dp, provider) Returns if the value is stored in the cache. If true, the priority is returned in the provider field
 IsSealed() Gets a value that indicates whether this instance is currently sealed (read-only)
 SetAnimation(dp, value) Sets the animated value of a property
 SetCurrentValue(dp, value) Sets the current value of a dependency property. The current value is set on the coerce field, without modifying source or animated value
 SetCurrentValueObject(dp, value) Sets the current value of a dependency property using a boxed value
 SetExpression(dp, expression) Sets the expression to be evaluated dynamically to obtain the value of the property
 SetValue(dp, value) Sets the local value of a dependency property
 SetValueObject(dp, value) Sets the local value (boxed) of a dependency property

From DispatcherObject

Name Description
 CheckAccess() Determines whether the calling thread has access to this DispatcherObject
 VerifyAccess() Enforces that the calling thread has access to this DispatcherObject
