Empty content when dynamically generated docking

[Marc]

after upgrading from Q3 2011 to Q3 2012 the following code doesn't work anymore and i cannot figure out why.

protected virtual void AddPane(RadPane pane)

        {

            var dockState = GetDockState(pane);

 

            RadSplitContainer splitContainer;

            if (dockState == null || dockState == DockState.FloatingDockable || dockState == DockState.FloatingOnly)

            {

                splitContainer = _dock.DocumentHost as RadSplitContainer;

                if (splitContainer == null)

                {

                    splitContainer = _factory.CreateSplitContainer();

                    splitContainer.SetValue(View.IsGeneratedProperty, true);

                    _dock.DocumentHost = splitContainer;

                }

            }

            else

            {

                splitContainer = _dock.Items.OfType<RadSplitContainer>().FirstOrDefault(

                    container => container.GetValue(RadDocking.DockStateProperty) as DockState? == dockState);

                if (splitContainer == null)

                {

                    splitContainer = _factory.CreateSplitContainer();

                    splitContainer.InitialPosition = dockState.Value;

                    splitContainer.SetValue(View.IsGeneratedProperty, true);

                    _dock.Items.Add(splitContainer);

                }

            }

 

            var paneGroup = splitContainer.Items.OfType<RadPaneGroup>().FirstOrDefault();

            if (paneGroup == null)

            {

                paneGroup = _factory.CreatePaneGroup();

                paneGroup.IsContentPreserved = true;

                paneGroup.SetValue(View.IsGeneratedProperty, true);

                paneGroup.SelectedItemRemoveBehaviour = SelectedItemRemoveBehaviour.SelectNone;

                splitContainer.Items.Add(paneGroup);

            }

 

            paneGroup.AddItem(pane, DockPosition.Center);
        }

now there is no visible content in this pane.

hoping for an answer...

I'm so sorry. Forget my question. It was my mistake and the problem was a completely different one.

Hope you didn't invest time here...
