Problem with data binding to DevExpress XtraGrid

I have a XtraGrid dropped on to a Winform. I have created 3 unbound columns named ID, StartTime and EndTime and set their unbound types as Int, DateTime and DateTime respectively. I have created a class:

public class Data
{
    public Data(int id, DateTime startTime, DateTime endTime)
    {
        this.id = id;
        this.startTime = startTime;
        this.endTime = endTime;
    }
    private int id;
    private DateTime startTime;
    private DateTime endTime;
    public int ID
    {
        get { return id; }
        set { id = value; }
    }
    public DateTime StartTime
    {
        get { return startTime; }
        set { startTime = value; }
    }
    public DateTime EndTime
    {
        get { return endTime; }
        set { endTime = value; }
    }
}

In the form constructor I created a List and bind the list to my gridcontrol at runtime

        List<Data> list = new List<Data>();
        list.AddRange(new Data[] {
                    new Data(1, Convert.ToDateTime("1:00:00 AM"),
                    Convert.ToDateTime("3:00:00 AM")),
                    new Data(2, Convert.ToDateTime("8:00:00 PM"),
                    Convert.ToDateTime("8:30:00 PM")),
                    new Data(3,开发者_StackOverflow Convert.ToDateTime("12:00:00 PM"),
                    Convert.ToDateTime("1:00:00 AM")),
                    new Data(4, Convert.ToDateTime("2:00:00 AM"),
                    Convert.ToDateTime("3:00:00 AM"))
                    });
        gridControl1.DataSource = list; 

When run the application, I get an empty grid. Somehow the columns that I created at design time are not filled correctly with the data at runtime. I try to do the same thing with no columns created at design time and the application run with correctly filled data. I am missing something.

Any ideas to debug the problem or solve the problem will be very appreciated. Thanks in advance

Set the FieldName property of your columns to ID, StartTime, EndTime (Case Sensitively!!!!). Also, I would suggest that you move your code to set the grid's DataSource to the form's Load event. This should help you.
