Is it possible to add the individual controls in an MDI window's titlebar?

Hello,

While you could set the docking window's ContextImageSource, it will just be an image (not a button), and it will appear left of the title.

To get a button in there or to have something next to the title bar buttons, you would need to make a new implicit Style for the WindowControl control that modifies its Template as you need, and put that new implicit Style in your app's Resources.  If your company owns WPF Studio, you can download the default styles/templates from the company account page on our site.  If your company has only licensed Docking/MDI individually, then you can email our support address and request the default styles/templates.  Let us know which version you use in your email.
