Automatic Automatic Automatic Automatic

Has the Automatic special value.

Forever Forever Forever Forever

Has the Forever special value.

TimeSpan TimeSpan TimeSpan TimeSpan

Has valid information in the TimeSpan component.


This value is used by the Duration.Type field, when you use C++ code and access the field data for a Duration.

For a Duration the Automatic and Forever values have different meaning depending on whether the Duration is being used for the Duration property on a Storyboard rather than on an individual storyboarded animation. For more info, see Storyboarded animations.

For C# and Microsoft Visual Basic there is no Type property but you can use HasTimeSpan to get similar information.
