Are there any utility methods to facilitate grouping shapes together?
Thank you for contacting support. I’m sorry to share with you that currently, you cannot group shapes together to move them all at once. It is not supported. I already have logged a feature request under ticket id DIAGRAMNET-50072 in our issue tracking system. Your request has also been linked to this issue and you will be notified as soon as it is supported. We’re sorry for your inconvenience.
As a workaround, you can group shapes together manually and drop this group shape into the new stencil. AddShape method allows to add group shape in the diagram. Please take a look over this helping article: http://www.aspose.com/docs/display/diagramnet/Add+and+Connect+Shapes
Please feel free to reply us in case of any confusion or questions.
