Unique identifier in the Xms/Xml

[ltiong]

Hello Alex,

I'm looking for a unique identifier for the Annotation in the Xms/Xml generated by GetAnnotationXml().

I see that the Annotation objects have a Guid member; is there any way to send that to the Xml?

Hello Lu,

Guid is unique for session and it is not saved with annotation. Why do you need this feature?

Best regards, Alexander

Hello Alex,

I was just curious if there was existing fucntionality.

I'm building an versioning/undo/redo subsystem for the Annotations in my application that outlasts the session. I needed a unique identifier so i can tell which individual Annotations are changed on the canvas, so that i can update those in the database.

I have been able to come up w/ a workaround, so I'm ok for now.

Thanks,
Lu
