Remarks

TargetedTriggerAction extends TriggerAction to add knowledge of another element than the one it is attached to. This allows a user to invoke the action on an element other than the one it is attached to in response to a trigger firing. Override OnTargetChanged to hook or unhook handlers on the target element, and OnAttached/OnDetaching for the associated element. The type of the Target element can be constrained by the generic type parameter. If you need control over the type of the AssociatedObject, set a TypeConstraintAttribute on your derived type.

Methods
