How to get the main RadPaneGroup (host)?
The following example is not possible to obtain the public RadPaneGroup (host). 

RadPane rp = new RadPane();
//rp.content = ......;
//......;
RadSplitContainer splitContainer = radDocking.DocumentHost as RadSplitContainer;
RadPaneGroup paneGroup = (splitContainer.Items as IEnumerable<RadPaneGroup>).FirstOrDefault(s => s.IsInDocumentHost == true);//(get error)
paneGroup.Items.Add(rp);

 Hi Sergei,

To solve the problem you are having you should cast the splitContainer.Items to IEnumerable rather than to IEnumerable<RadPaneGroup>. The code snippet shows how to cast the splitContainer.Items to IEnumerable:

var paneGroup = (splitContainer.Items as IEnumerable).OfType<RadPaneGroup>().FirstOrDefault(s => s.IsInDocumentHost == true);

Hope this is helpful.

All the best,
