Looking for the ability to restrict movement of DockItems

I've been looking for a way to restrict the movement of docked items. Ex: Only allow them to be tabbed documents or autohide items, not floating items, or perhaps only dock to the top or bottom of the screen.  Also, I would like to not allow the user to hide/close an item.

I found a reference to AllowedDockLocations in some documentation, but can't seem to find any reference as to how to use it.  (https://www.mindfusion.eu/onlinehelp/wpfpack/F_MindFusion_UI_Wpf_DockControl_All...)

I would like to use the functionality of the docking control, but don't want the user to be able to do whatever they want with it.

Sorry, AllowedDockLocations was removed when we moved away from fixed five dock locations (now you can create an arbitrary tree structure of dock elements). We'll add some validation events to let you decide what's allowed.

This version raises WindowDocking and WindowUndocking events to let you prevent users from docking or undocking -
https://mindfusion.eu/_temp/dock_validate.zip

E.g. prevent users from removing items from tabbed documents area -
Code
Select All
void dockControl_WindowUndocking(object sender, DockValidationEventArgs e)
{
	e.Cancel = e.DockWindow is TabbedDocument;
} 



Prevent users from adding to the tabbed documents area or creating a new one -
Code
Select All
void dockControl_WindowDocking(object sender, DockValidationEventArgs e)
{
	if (e.DockTarget is TabbedDocument &&
		(e.DockType == DockType.AddTab || e.DockType == DockType.Split))
		e.Cancel = true;
}

Slavcho
