Crystal報表查看器給我錯誤：「提供的無效參數。無法打開行集。」

Question

我有一個水晶報表，那就是充滿存儲過程，但是當我在.rpt文件放在程序的任何參數，它給我的錯誤一樣

「提供的參數無效。無法打開一排排「。

我的代碼如下：

public void GroupwiseRegistrationReport() 
{ 
    SqlConnection connection; 
    DataSet ds = new DataSet(); 
    DataTable dt = new DataTable(); 
    connection = gen.con; 
    string SP = ""; 
    SqlCommand command = connection.CreateCommand(); 
    SqlTransaction transaction = null; 

    try 
    { 
     connection.Open(); 
     transaction = connection.BeginTransaction(); 
     if (rblReportFrom.SelectedValue == "0") 
     { 
      SP = "SPGroupwiseIndustriesEM1Report"; 
     } 
     else 
     { 
      SP = "SPGroupwiseIndustriesEM2Report"; 
     } 

     ValueData = new ArrayList(); 

     ParameterData[0] = "@fromdate"; 
     ValueData.Add(txtTotalBetweenFrom.Text.ToString().Trim()); 

     ParameterData[1] = "@todate"; 
     ValueData.Add(txtTotalBetweenTo.Text.ToString().Trim()); 

     ds = gen.FunSearch_Trans(ParameterData, ValueData, SP, transaction, command); 
     dt = ds.Tables[0]; 
     if (ds.Tables[0].Rows.Count > 0) 
     { 
      if (rblReportFrom.SelectedValue == "0") 
      { 
       repdoc.Load(Server.MapPath("~\\admin\\Reports\\Groupwise-EM-I-Registration-Report.rpt")); 
      } 
      else 
      { 
       repdoc.Load(Server.MapPath("~\\admin\\Reports\\Groupwise-EM-II-Registration-Report.rpt")); 
      } 
      repdoc.SetDataSource(ds.Tables[0]); 

      configureCrystalReports(); 
      crvMSMEReportViewer.ReportSource = repdoc; 
      //Response.Buffer = true; 
      //Response.ClearContent(); 
      //Response.ClearHeaders(); 

      //repdoc.ExportToHttpResponse(ExportFormatType.PortableDocFormat, Response, true, "Exported Report"); 

      tablereportviewer.Visible = true; 
     } 
     else 
     { 
      tablereportviewer.Visible = false; 
      message("No Records Found."); 
     } 
     transaction.Commit(); 
    } 
    catch (Exception ex) 
    { 
     tablereportviewer.Visible = false; 
     error.LogError(ex); 
     transaction.Rollback(); 
    } 
    finally 
    { 
     connection.Close(); 
    } 
} 

我缺少的東西還是什麼我不能弄明白請幫助我..

而且這是對付水晶報表的最佳方式，它是使用數據集還是直接存儲過程？

更新

我改變了我的代碼，如下圖所示，但現在是給我這樣的消息：「缺少參數值 。」但我只有兩個參數來傳遞這是「@fromdate」和「@todate」

這裏是一個代碼片段：

doc = new ReportDocument(); 
     doc.Load(Server.MapPath("~\\admin\\Reports\\Groupwise-EM-II-Registration-Report.rpt")); 
     doc.SetDatabaseLogon(ConfigurationManager.AppSettings["userName"], ConfigurationManager.AppSettings["pwd"], ConfigurationManager.AppSettings["serverName"], "databaseName", false); 
     doc.SetParameterValue("@fromdate", txtTotalBetweenFrom.Text.ToString()); 
     doc.SetParameterValue("@todate", txtTotalBetweenTo.Text.ToString()); 
     crvMSMEReportViewer.ReportSource = doc; 
     crvMSMEReportViewer.RefreshReport();

protected void Page_Load(object sender, EventArgs e) 
    {  
     if (Session["ReportDataSet"] != null) 
     { 
      crvAccountReportParameter.ReportSource = (ReportDocument)Session["ReportDataSet"]; 
     } 
    } 
private void LoadReport() 
{ 
    doc = new ReportDocument(); 
    DataSet dsData = null; 
    dsData = objAccountReportBAL.getAccountRegister(txtTotalBetweenFrom.Text.ToString(), txtTotalBetweenTo.Text.ToString());    
    doc.Load(Server.MapPath("CrSalesReport.rpt"));  
    doc.SetDataSource(dsData.Tables[0]); 
    Session["ReportDataSet"] = rptDoc; 
    crvAccountReportParameter.ReportSource = rptDoc; 
    crvAccountReportParameter.DataBind(); 
}
