I’m trying to follow the instructions here:
to create a subclass of CustomAnnotation. I have copied the attributes given in the example (VerticalAnchorPoint=”Bottom” HorizontalAnchorPoint=”Center”) but I still get the error “An attribute name is missing” on anything I put after the attributes. Are there other attributes that may be required for CustomAnnotation, not given in this example?

I have an application for which the VerticalLineAnnotation is a near perfect fit. However, to make it easier to add these annotations from the AnnotationCreatioinModifier, I would like to derive a new annotation class from VerticalLineAnnotation with a couple of new dependency properties, and new label style using these properties. Is this possible? I’ve looked through the forum and existing examples, and can’t find relevant examples. Can you point me in the right direction?
