Theme consistency | Infragistics Forums

You can define your own themes if you want. If you just want to have Onyx/RoyaleStrong but don't want to define a new custom/washgroup theme then you can register a theme that just references the same xaml files. So the following could be used to register an Onyx theme that loads the XDM's Office2kBlack and a RoyaleStrong theme that loads the XDM's Office2kBlue.
