Adding a border with dropshadow to TabbedMdiContainer or Host

Hi Chris,

Window tabs are mainly defined in the DockingWindow.xaml file.  They are effectively the styles for the controls like ToolWindow and DocumentWindow, since the tab is how the controls are represented in UI.

The Containers.xaml file would have styles for the containers like TabbedMdiContainer, etc.

Right, I was expecting the solution to involve changing the TabbedMdiContainer, but I don't see a way to change it in the way that I need. I don't see a key that holds an element hierarchy for that section, and changing the style templates directly would be pointless since the ones I'm viewing aren't the ones referenced by the project. Am I missing something?

Hi Chris,

Anything related to rendering of the TabbedMdiContainer is in the TabbedMdiContainer Style in Containers.xaml.  The items (rendered as tabs) presented in its ItemsPresenter would be the DocumentWindow and ToolWindow instances, with the DockingWindowTabbedMdiDocumentTemplateKey template set, which is defined in DockingWindow.xaml.  Everything that is rendered on our end for a tabbed MDI container is done through those two things and the resources they use.

If you want to change the TabbedMdiContainer Style, you'd need to clone it and put the modified clone in your app's Resources.  If you want to change the tab styles, you'd need to clone just about everything in DockingWindow.xaml (since different triggers in the docking window Styles activate different templates) and put the modified clones in your app's Resources.
