1. Add 4 ToolWindows - left, top, right, bottom.
2. Add one DocumentWindow at the center.
3. In the Load event set the MainDocumentContainerVisible property to false.
Please refer to the attached sample gif files. Even though the document container is not shown, the docking guides for the tabbed document are visible.
I have also updated your Telerik points.
Currently, the possible solution that I can suggest is to handle the DragDropService.PreviewDockPosition event and specify the AllowedDockPosition argument in order to control which docking guides to show.
public
RadForm1()
{
InitializeComponent();
DragDropService service =
this
.radDock1.GetService<DragDropService>();
service.PreviewDockPosition += service_PreviewDockPosition;
}
private
void
service_PreviewDockPosition(
object
sender, DragDropDockPositionEventArgs e)
{
e.AllowedDockPosition = AllowedDockPosition.Left | AllowedDockPosition.Right | AllowedDockPosition.Top | AllowedDockPosition.Bottom ;
}
