Hi John,
can you provide more details what do you want to achieve?
Unfortunately, you post has subject only, but not text, and also the shared picture is quite useless, because in very low resolution.
Please, read the best practices, and
Because you mentioned Customize dialog, are you aware of concept of DGNLIB, how to create own one and configure ORD to use it? Also, is there any reason why Customize tool (which is maintained primarily for backward compatibility) and not Ribbon customization is used?
With regards,
Jan
