我必须用 dbcoommand 填充 gridview。

我写的代码是：

EntityConnection entityConnection = (EntityConnection)db.Connection;
        DbConnection storeConnection = entityConnection.StoreConnection;
        storeConnection.Open();
DbCommand command = storeConnection.CreateCommand();
    command.CommandType = CommandType.StoredProcedure;
    command.Parameters.Add(new SqlParameter("StatoID", DropDownListStato.SelectedValue));
    command.Parameters.Add(new SqlParameter("InizioPeriodo", DateTime.Parse(TxtIntervalloDataInizio.Text + " 00:00")));
    command.Parameters.Add(new SqlParameter("FinePeriodo", DateTime.Parse(TxtIntervalloDataFine.Text + " 23:59")));
    command.Parameters.Add(new SqlParameter("AccountID", ddlDipendenti.SelectedValue));
    command.Parameters.Add(new SqlParameter("Prenotazioni", ChkPrenotazioni.Checked.ToString()));
    command.Parameters.Add(new SqlParameter("PrenotazioniEffettuate", DropDownListPrenotazioniEffettuate.SelectedValue == "True" ? 1 : 0));
    command.Parameters.Add(new SqlParameter("UscitaServizio", DropDownListUscitePerServizio.SelectedValue == "True" ? 1 : 0));

    command.CommandText = "up_missioni_get_data";        
    GridView1.DataSource = command.ExecuteReader();

该命令正确返回行，但未填充网格视图。为什么 ？网格视图的标题是：

<asp:GridView ID="GridView1" runat="server" AllowPaging="True" OnRowDataBound="GridView1_RowDataBound"
            AllowSorting="True" AutoGenerateColumns="False" DataKeyNames="MissioneID"  
            PageSize="20" Width="100%" CellPadding="4" CellSpacing="1"
              GridLines="None" >

我能怎么做？

谢谢
