Issue with stored object viewing on datatable and gridview

My program displayed an unexpected result on gridview: I want to show all fields of the key value, so please help me. My object:

public class Id
	{  
		public string CallTime { set; get; }  
		public string CallerID { set; get; }  
		public string Destination { set; get; }  
	}  
	class Report  
	{  
		[BsonId]  
		public Id key { set; get; }  
		public string Status { set; get; }  
		.  
		.  
}

Stored

var reports = db.GetCollection<Report>("reports");
foreach (Report rp in lsRe)
	reports.Insert(rp);

Query

var col = db.GetCollection<Report>("reports");
col.Include(x=>x.key.CallTime)
	.Include(x => x.key.CallerID)
	.Include(x => x.key.Destination)
	.FindAll());

Sorry for my bad English, thank you.

@bolner I’m honestly not sure anymore if the screenshot that is being showed is LiteDB Studio or another self-made program. @anh309 Can you confirm?

@anh309 In any case, you don’t need to do the includes as those are only required when you’re using BsonRefs. What you might want to do is a select after the fetching that projects the data in the format that you want it to be (or override the ToString() method of the class Id, like @bolner already suggested)

class Program
{
    static void Main(string[] args)
    {
        var db = new LiteDatabase(new MemoryStream());
        var col = db.GetCollection<Report>();

        col.Insert(new Report
        {
            Key = new Id
            {
                CallerId = "callerId",
                CallTime = "123",
                Destination = "The other side"
            },
            Status = "Answered"
        });

        var fetchedList = col
            .FindAll()
            .Select(report =>  new {report.Key.CallTime, report.Key.CallerId, report.Key.Destination, report.Status})
            .ToList();
    }

    class Id
    {
        public string CallTime { set; get; }
        public string CallerId { set; get; }
        public string Destination { set; get; }
    }

    class Report
    {
        [BsonId]
        public Id Key { set; get; }

        public string Status { set; get; }
    }
}
