The compass is out of place when specific height is set to the dock and the window is made smaller than the docking height

Dragging objects from outside control shouldn't be allowed in specific cases. In cases where the RadDocking control cannot use the dragged data, the drop operation shouldn't be allowed.

Regions in panes content are not resolved when the pane is unpinned and collapsed. This happens only when you change the regions in runtime while the pane is unpinned and collapsed.

Got this weird behavior with RadDocking with multiple monitors.

As you could see the pane is being opened on the wrong side.

This happens only when the application is fully maximized, if its resized then this problem does not occur.

I am not able to reproduce this with a simple example. But you could contact me I can help in investigation.

When the DropDownDisplayMode of the RadPaneGroup is set to Visible and that group is placed inside the DocumentHost calling the RemoveFromParent from a button places in the HeaderTemplate of the RadPane causes that RadPane instance to not be removed from the memory.

Loading a layout containing a single empty RadPaneGroup inside the DocumentHost causes the IsInDocumentHost property of the group to return false.

If the IsHidden property of a Pane placed inside the Document host is bound to a property in the ViewModel with value of True the IsHidden property at start-up is reset to False.

Possible workaround:

A custom RadDocking control can be created, in which the OnCreateAutomationPeer() method is overridden. OnCreateAutomationPeer() should return a custom RadDocking AutomationPeer, in which the ToolWindowAutomationPeer is removed from the collection of child elements of RadDocking AutomationPeer.
Approach demonstrated in the attached project.
