Detect if DockingWindow is docked to PrimaryDockHost

Posted 7 years ago by Anton Chochia

Version: 17.2.0662

Hi,

I need to detect if DockingWindow is docked to PrimaryDockHost when i drag docking window from floating window to primary dock host. When I undock first window and drag to somethere I receive DockSite.WindowsDragged event but both it's properties IsFloating is false and DockSite equals to PrimaryDockHost. If I undock the second window and drag into floating window container with first window then it's IsFloating = true and DockSite is not PrimaryDockHost. Currently, Code excerpt bellow:

if (!dockingWindow.IsFloating && dockingWindow.DockHost == dockingWindow.DockSite.PrimaryDockHost)

{

// Do something

}

Is there way to correctly detect if window dragged and docked into PrimaryDockHost?

Hi Anton,

I just pasted your code into a sample and tried to reproduce this but was unable to. Everything is working as expected in the lastest version and your 'if' statement fires at the right time.

I did look back at old code and some of the first builds of the Docking/MDI rewrite back in early 2016 did have the event fire before the layout change completed. I suspect you are on one of those very old builds. I'd recommend updating to a newer build, like 2017.2 and it will work better there.

Hi,

I'm on latest version (2017.2.0622). It works for any further dragged docking windows except for first one when I drag them into same floating window.

Hi,

The behavior is reproduced when DockSite.UseDragFloatPreviews=true

Support ticket 262-21A7EB71-0011 is created. The sample project was sent in separate email.

Thanks.

Hi Anton,

Thanks for the sample. It didn't occur until that UseDragFloatPreviews property was set. We updated some code for the next build to resolve the issue.
