TriggerActionCollection TriggerActionCollection TriggerActionCollection Class

Represents a collection of BeginStoryboard objects.

Syntax

Declaration

public sealed class TriggerActionCollectionpublic sealed class TriggerActionCollectionPublic NotInheritable Class TriggerActionCollection
<EventTrigger>
  oneOrMoreBeginStoryboards
</EventTrigger>

Remarks

Enumerating the collection in C# or Microsoft Visual Basic

A TriggerActionCollection is enumerable, so you can use language-specific syntax such as foreach in C# to enumerate the items in the collection. The compiler does the type-casting for you and you won't need to cast to IEnumerable<BeginStoryboard> explicitly. If you do need to cast explicitly, for example if you want to call GetEnumerator, cast to IEnumerable<T> with a BeginStoryboard constraint.
