Remarks

In a versioned geodatabase, these properties apply to all versions and are not versioned. After creating an annotation feature class, modifying these properties may cause problems with the drawing and selection of annotation features. Adding new symbols to the SymbolCollection or changing the AutoCreate and UpdateOnShapeChange properties are the only recommend modifications. Deleting or modifying symbols in the SymbolCollection requires updating all annotation features whose elements reference the group symbol. When adding new symbols to the SymbolCollection use the AddSymbol method of ISymbolCollection2, which will automatically assign a unique ID to the symbol. As with any schema related change, it is recommended that an exclusive schema lock be obtained before calling the UpdateProperties method.

IAnnoClassAdmin2 was added to include the UpdateOnShapeChange property for an AnnotationFeatureClassExtension. This property indicates whether or not an annotation feature is automatically recreated in response to a change in the geometry of its linked feature.

See IAnnoClassAdmin3 for more properties of the AnnotationFeatureClassExtension.
