Hello,

Would you please let me know how to know which window become floating in FloatingWindowOpening event?

I'm trying as the following now.

private void DockSite_FloatingWindowOpening(object? sender, FloatingWindowOpeningEventArgs e)
        {
            IEnumerable<DockingWindow>? floatingWindows;
            if (e.DockHostChild is Workspace workspace
                && workspace.Content is TabbedMdiHost tabbedMdiHost
                && tabbedMdiHost.Child is TabbedMdiContainer tabbedMdiContainer)
            {
                // DocumentWindow
                floatingWindows = tabbedMdiContainer.Windows.Where(x => x.IsFloating);
            }
            else if (e.DockHostChild is ToolWindowContainer toolWindowContainer)
            {
                // ToolWindow
                floatingWindows = toolWindowContainer.Windows.Where(x => x.IsFloating);
            }
            else
            {
            }
        }

Hello,

If this opening event is for a floating window open commit (not a drag preview), the e.DockHost.Child property will return the root object being floated.  For tool windows, this would be a ToolWindowContainer.  For tabbed documents, it would be a Workspace. 

I think a lot of the logic you provided above will work as-is.  But you don't need the Where() LINQ calls since everything in those containers is part of this floating operation.
