Docked tool window becomes floating when closed and reopened

Docking/MDI for WPF Forum

Posted 5 years ago by Daniel F.
Version: 17.2.0662
Platform: .NET 4.7
Environment: Windows 10 (64-bit)

We noticed the following behavior:

1. Undock and float tool window A
2. Redock tool window A
3. Close tool window A
4. Serialize and save the layout
5. Load another layout that does not open tool window A
6. Load the saved layout
7. Open tool window A (".Activate")
8. -> tool window A floats; expecation is that it is docked, because it was docked when it was closed

For some reason this problem does only seem to occur when another layout is loaded between closing and opening the tool window.

I could attach a solution that demonstrates the problem if the steps above are not quite clear.

Thanks in advance for any input regarding this issue.

Best Regards,

Hi Daniel,

Thank you for the steps that show the issue.  I was able to reproduce this in the old 2017.2 version you have.  It appears to have been fixed in a v2018.1 build at some point.

Thank you for the feedback. The bug seems to be present in 18.1.673 but not the newest version (19.1) so we'll be sure to update.

Thanks again,


The latest build of this product (v24.1.2) was released 2 months ago, which was after the last post in this thread.
