StandardSwitcher does not show any content in its preview area if the selected docking window contains a WindowsFormsHost control. Based on http://www.actiprosoftware.com/community/thread/3528/image-on-standard-switcher-window I tried to override OnSelectedWindowChanged, extract a bitmap of the Forms control, convert it to a WPF bitmap, and assign it to the according StandardSwitcher element. This is my code so far:
Unfortunately it does not work. Changes to _previewBorder have no effect on the view. May I ask you for your suggestions?
