🔹 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. |
◆ Dependency Property ◆ Reflection Property
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. |
◆ Dependency Property ◆ Reflection Property

Methods
From DependencyObject
| Name | Description |
|---|---|
| ◆ ClearAnimation(const DependencyProperty*) | Clears the animation value of a property |
| ◆ ClearLocalValue(const DependencyProperty*) | Clears the local value of a property The property to be cleared is specified by a DependencyProperty identifier |
| ◆ CoerceValue(const DependencyProperty*) | 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(const DependencyProperty*) | Returns the base value without animation nor coerce (this never returns Expression like GetLocalValue) |
| ◆ GetExpression(const DependencyProperty*) | Gets the expression, if any, used to evaluate the specified property value |
| ◆ GetLocalValue(const DependencyProperty*) | Returns the local value of a dependency property, if it exists |
| ◆ GetValue(const DependencyProperty*) | Returns the current effective value of a dependency property on this instance of a DependencyObject |
| ◆ GetValueObject(const DependencyProperty*) | Returns the current effective value of a dependency property on this instance of a DependencyObject as a boxed value |
| ◆ GetValueProvider(const DependencyProperty*) | Gets the provider that returns the effective value for the specified dependency property |
| ◆ HasAnimatedProperties() | Returns true if there is any animated property |
| ◆ InvalidateProperty(const DependencyProperty*, uint8_t) | Re-evaluates the effective value for the specified dependency property if necessary If null is passed, a full re-evaluation could be needed |
| ◆ IsCached(const DependencyProperty*, uint8_t*) | 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(const DependencyProperty*, SetValueType<T>::Type) | Sets the animated value of a property |
| ◆ SetCurrentValue(const DependencyProperty*, SetValueType<T>::Type) | Sets the current value of a dependency property. The current value is set on the coerce field, without modifying source or animated value |
| ◆ SetCurrentValueObject(const DependencyProperty*, BaseComponent*) | Sets the current value of a dependency property using a boxed value |
| ◆ SetExpression(const DependencyProperty*, Expression*) | Sets the expression to be evaluated dynamically to obtain the value of the property |
| ◆ SetValue(const DependencyProperty*, SetValueType<T>::Type) | Sets the local value of a dependency property |
| ◆ SetValueObject(const DependencyProperty*, BaseComponent*) | 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 |
