Possible docking problem when using LazyLoad persistence

Docking/MDI for WPF Forum

Hi,

If you perform the following steps on your Docking -> Lazy Loading sample:

  • Click Activate -> Create Programmatic ToolWindow 1
  • Click on the pin of Programmatic ToolWindow 1 so that it auto-hides
  • Hover the mouse over Programmatic ToolWindow 1 so that it is visible - then click the x to close it
  • Click on Activate -> Activate Programmatic ToolWindow 1

At this point I would expect Programmatic ToolWindow 1 to be in auto-hide mode, but actually it is docked. I would expect the window to be in auto-hide mode at this point.

When I run this in my application I can see that the ToolWindow State property is auto-hide after I have created the tool window, but as soon as I call Activate the State changes to docked. The behaviour is the same if I call ToolWindow.Activate or ToolWindow.Open.

Is this behaviour by design or is it a bug? If it is by design then would it be possible to change it to have different bevahiour for the Activate and Open methods?

Regards,

Keith

Hi Keith,

By default, ToolWindows will not restore to the auto-hide state. You can change this behavior by setting DockSite.CanToolWindowsRestoreToAutoHideState to true.

Hi and thanks for your reply.

I have modified your sample to set CanToolWindowsRestoreToAutoHideState to true, but I still get the same result. Please could you verify that it works for you?

Regards,

Keith

Hi Keith,

Sorry, I misread your repro steps and was closing the Window and relaunching the sample then activating. You are correct, that is a bug and we have corrected it for the next maintenance release.
