I have an application that has the following hierarchy - Locations --> Buildings --> Rooms --> Assets.  I am creating a datagrid with all assets and need to display the room, building, location as well.   Currently, I am having issues getting the Building and Location when I populate assets.  I was able to get the Room data using the Include method on my query.  Here is my code snippet.  
 

private void LoadData()

{

// _mgr.ExecuteQueryAsync(_mgr.Rooms, GotRooms, null);

// _mgr.ExecuteQueryAsync(_mgr.Buildings, GotBuildings, null);

_mgr.ExecuteQueryAsync(_mgr.Assets.Include("Room"), GotAssets, null);

}

private void GotAssets(EntityFetchedEventArgs args)

{

if (args.Error != null)

{

WriteMessage(args.Error.Message);

}

else

{

foreach (Asset asset in args.Result)

{

_assets.Add(asset);

}

 

}

}

_mgr.Assets.Include("Room")



_mgr.Assets.Include("Room.Building.Location") will bring the entire object graph into the cache
