Howto get the AnnotationProperties of an IAnnotationLayer?

[PieterLinks]

Hello,

How do I get the AnnotationProperties of a IAnnotationLayer? A non-annotation IFeaturelayer is also a IGeoFeatureLayer, which has an IAnnotateLayerPropertiesCollection, but an IAnnotationLayer has not.

I'm aware of the IAnnoClass and IAnnoClassExtension, but how to get there?

IAnnoClass annoClass = featureLayer.FeatureClass as IAnnoClass doesn't work, it returns null.

Kind regards,

Pieter

Found after a search on the web in annotation - ArcObjects Anno Classes - Geographic Information Systems Stack Exchange

IAnnotationClassExtension annoClassExtension = featureLayer.FeatureClass.Extension as IAnnotationClassExtension;

IAnnotateLayerPropertiesCollection annoLayerPropsCollection = annoClassExtension.AnnoProperties;

...  etcetera

Thanks anyway,

Pieter
