Sometimes PreviewKeyDown is not fired when Window is floating.

Docking/MDI for WPF Forum

This is an intermittent issue.

When the docking window is floating (undocked), the FrameworkElement.PreviewKeyDown is not fired. As soon as it is docked, the event is fired normally.

Any ideas what could be causing this issue?

Kind Regards,

Hi Vinay,

Which element are you attaching to for that event?  If you mean you are attaching to something in the main Window's visual tree, then that is correct, events from rafted (undocked) docking windows won't ever bubble up to it since those are contained in a separate rafting Window and bubble events don't cross WPF Window boundaries.

You are best off putting handlers in the root control of each docking window's content.
