Hello,

I am using an instance of DockSiteLayoutSerializer to call LoadFromString, using a dockSite as a parameter:

DefaultDockSiteLayoutSerializer.Instance.LoadFromString(_settings.Layout, _dockSite);

For some reason, somewhere in LoadFromString is firing an Unloaded event on ContentControls within the DockSite.  I don't want it to fire Unloaded because other objects are listening for that Unloaded event and reacting like it was unloaded when I am just trying to load the DockSite settings layout upon opening the view.  Oddly enough, the Unloaded event is only fired in LoadFromString when I run the program from the executable, it doesn't happen when I run from Visual Studio.  Do you know what is going on here?

Thanks,

Joel

Hi Joel,

I'm not sure since all we are doing is readjusting the control hierarchy in layout loads.  We've found in numerous cases (not even related to Docking/MDI usage) that the Unloaded event isn't always reliably fired by native WPF.  I might suggest that you watch something more like our DockSite.WindowsClosed event since that will fire correctly as a docking window is removed from the layout.
