Populating treeview with properties like XtraGridBindingManager


   I would like to find out how the XtraGridBindingManager is building up the properties treeview 
 
I got to the point of getting the properties, but still not the related properties
 

Entity emp = _entityManager.GetNullEntity<T>();

foreach (var item in emp.EntityAspect.EntityMetadata.EntityProperties)

{
listOfProperties.Add(item);

}

foreach (var item in emp.EntityAspect.EntityMetadata.NavigationProperties)

{
listOfProperties.Add(item);
}
