Am I right in observing that the Ribbon, Docks, and Grid do not share all the same themes? If so, what is the reasoning?
There are a core set of themes in each assembly that are the same and are usually chosen based on the current os theme using the standard wpf theming infrastructure (e.g. aero, luna normal, luna olive, royale, etc.). We also have several theme assemblies (Water, Wind, ForestGreen, etc.) that should contain themes for all of the controls. However, DataPresenter & Ribbon have themes named Onyx and RoyaleStrong that are not currently defined in XamDockManager. I can't state the exact reason but I think its because the themes within the assembly are usually to deal with the various os themes and separate assemblies can be chosen by the developer to use a different theme. Note, you can define your own themes if you wish. I believe there are help topics that cover how to do this.
Thanks Andrew! Its just that Onyx and RoyaleStrong are my favorites and I was bummed when they didn't exist for the Dock! I was hoping to give a drop-down to my users to pick a theme and then apply it the Ribbon, Dock, and Grid all at once. I guess I can do a substitute routine for the Dock so if Onyx is chosen, I substitute Office2007Black, etc.
