WPF DockingManager - Side Dock will not stay open when AutoHidden and WindowsFormsHost is clicked.

Asked On January 22, 2020 08:49 PM UTC

I have a legacy application that is a mix of WPF and WinForms.  I need to have auto hidden docks on the left side of the docking manager - sometimes these will host WPF user controls, and sometimes they will need to host WinForms user controls.  

However, I am running into a problem...

- When I expand the dock that contains the the WPF user control and click inside the user control all works fine - the dock stays open and allows me to use the control.  

- However, if I try the same thing with the dock that contains the WinForms user control, the dock immediately collapses when I try to click inside the user control.

Am I doing something wrong?  I've attached a simple example that shows the problem I am having.

Thanks for your help!
