Binding database data to the GridView in ASP.Net

I try to bind database data to the gridview in c# and asp.net. But I couldn't see the datas in the gridview.Rows are added to the gridview but they are empty. When I run that query in SQLServer, it gives the correct result.I didn't add or change any code to the asp part.Should I? I couldn't find where is the problem :( please help..

myConnection = WebConfigurationManager.ConnectionStrings["KutuphaneConnectionString"].ConnectionString;
connect = new SqlConnection(myConnection);
command = new SqlCommand();
connect.Open();
command.Connection = connect;

 string komut = "SELECT K.ad,K.yazar,K.baskiNo,O.sonTeslimTarihi FROM OduncIslemleri O,Kitap K WHERE O.kullaniciId=" + Session["id"] + " AND O.kitapId = K.id;";
        try
        {
            SqlCommand sqlCommand = new SqlCommand();

                sqlCommand = connect.CreateCommand();
                sqlCommand.CommandText = komut;
                SqlDataAdapter sda = new SqlDataAdapter(sqlCommand.CommandText, connect);
                SqlCommandBuilder scb = new SqlCommandBuilder(sda);
                //Create a DataTable to hold the query results.
                DataTable dTable = new DataTable();
                //Fill the DataTable.
                sda.Fill(dTable);
                GridView1.DataSource = dTable;
                GridView1.DataBind();

        }
        catch (SqlException)
        {
            //Console.WriteLine(e.StackTrace);
        }

reader.Close();
connect.Close();

Here is the correct answer : 

myConnection = WebConfigurationManager.ConnectionStrings["KutuphaneConnectionString"].ConnectionString;
connect = new SqlConnection(myConnection);
string sorgu = "select K.ad,K.yazar,K.baskiNo,O.sonTeslimTarihi from Kitap K, OduncIslemleri O where O.kitapId = K.id and O.kullaniciId = "+ Session["id"];
SqlDataAdapter sadp = new SqlDataAdapter(sorgu, connect);
DataSet ds = new DataSet();
sadp.Fill(ds);
this.GridView1.DataSource = ds.Tables[0];
this.GridView1.DataBind();
connect.Close();

I also used template fields in Gridview. Also autogeneratedFields should be true. I hope this helps to the people who have the same problem

I think you have to use a BindingSource Control, you set the DataSource of it to the DataTable, and then set the GridView's DataSource to the BindingSource.

Try creating a DataSet and populate that using Fill instead. I've never seen Fill used on a DataTable - and can't find that particular overload on MSDN. My suspicion is, though, that such an overload would not modify the existing schema of the DataTable (which, since it's only just been created prior to use in your example, would mean that it has no columns).

watch for another event triggered after the bind that could be clearing the rows
