変更後、クリスタルレポートに同じデータが表示されます

Question

c＃.netデスクトップアプリケーションのCrystalレポートのクエリに従ってデータを表示しています。問題の原因は、私がクエリを変更すると、クエリが変化していることと、そのデータを示すテンポラリテーブルのクエリにもよるが、クリスタルレポートでは、クエリの後に以前と同じデータを表示している変更する。

例：請求書番号1を印刷したいので、その時は大丈夫です。しかし、私はその時に請求書2を印刷したいと思っています。私はできない法案ここには2

を印刷するだから、なぜ、それはだある

private void btn_previewdocument_Click(object sender, EventArgs e) 
    { 
     try 
     { 
      string mtmptbl = "TmpRetailInvoicePrint"; 
      RetailInvoicePrint frm = new RetailInvoicePrint(); 
      Cursor = Cursors.WaitCursor; 
      timer1.Enabled = true; 

      ReportDocument cryRpt = new ReportDocument(); 
      SqlCommand MyCommand = new SqlCommand(); 
      SqlConnectionStringBuilder builder = new SqlConnectionStringBuilder(cn.ConnectionString); 
      ConnectionInfo crConnectionInfo = new ConnectionInfo(); 
      TableLogOnInfo crtableLogoninfo = new TableLogOnInfo(); 

      string qryPreviewDocument = " SELECT Client.clientname as ClientName, " + System.Environment.NewLine; 
      qryPreviewDocument += " RetailInvoice.invoiceno as InvoiceNo, " + System.Environment.NewLine; 
      qryPreviewDocument += " RetailInvoice.pono as PoNO, RetailInvoice.issuedate as IssueDate, RetailInvoice.duedate as DueDate, " + System.Environment.NewLine; 
      qryPreviewDocument += " RetailInvoice.discount as Discount, RetailInvoice.shipping as Shipping, RetailInvoice.tax as Tax, RetailInvoice.vat as Vat, " + System.Environment.NewLine; 
      qryPreviewDocument += " RetailInvoice.sese as Sese, RetailInvoice.paymenttype as PaymentType, RetailInvoice.chequeno as Chequeno, RetailInvoice.totalamt as TotalAmt, " + System.Environment.NewLine; 
      qryPreviewDocument += " RetailInvoice.description as Description, RetailInvoice.paymentpaid as PaymentPaid, RetailInvoice.subtotal as Subtotal, " + System.Environment.NewLine; 

      qryPreviewDocument += " RetailInvoicePayment.productid as ProductName, RetailInvoicePayment.uom as Uom, " + System.Environment.NewLine; 
      qryPreviewDocument += " RetailInvoicePayment.quantity as Quantity, RetailInvoicePayment.price as Price" + System.Environment.NewLine; 

      qryPreviewDocument += " into " + mtmptbl + " " + System.Environment.NewLine; 

      qryPreviewDocument += " from tbl_retailinvoice RetailInvoice LEFT OUTER JOIN tbl_retailinvoicepayment RetailInvoicePayment " + System.Environment.NewLine; 
      qryPreviewDocument += " ON RetailInvoice.invoiceno = RetailInvoicePayment.invoiceno " + System.Environment.NewLine; 
      qryPreviewDocument += " LEFT OUTER JOIN tbl_clientdetail Client ON RetailInvoice.clientid = Client.clientid " + System.Environment.NewLine; 

      qryPreviewDocument += " where RetailInvoice.BranchID = " + lbl_branchid.Text + " " + System.Environment.NewLine; 
      qryPreviewDocument += " and RetailInvoice.YearID = " + lbl_yearid.Text + " " + System.Environment.NewLine; 
      qryPreviewDocument += " and RetailInvoice.invoiceno = " + txt_invoice.Text + ""; 


      string SQL = "select upper(name) as TABLE_NAME FROM sysobjects WHERE type = 'U' and name = '" + mtmptbl + "' order by name"; 
      DataTable dt = new DataTable(); 
      SqlDataAdapter da = new SqlDataAdapter(SQL, cn); 
      da.Fill(dt); 
      if (dt.Rows.Count > 0) 
      { 
       string qrydrop = "drop table " + mtmptbl + ""; 
       SqlCommand cmd = new SqlCommand(qrydrop, cn); 
       cn.Open(); 
       cmd.ExecuteNonQuery(); 
       cn.Close(); 
      } 

      MyCommand = new SqlCommand(qryPreviewDocument, cn); 
      MyCommand.CommandType = CommandType.Text; 
      cn.Open(); 
      MyCommand.ExecuteNonQuery(); 
      cn.Close(); 

      string crReportPath = Application.StartupPath.Replace("bin\\Debug", "") + "\\Print"; 

      cryRpt.Load(crReportPath + "\\RptRetailInvoice.rpt"); 

      builder.ConnectionString = System.Configuration.ConfigurationSettings.AppSettings["con"]; 
      string dbName = builder.InitialCatalog; 
      string dbDataSource = builder.DataSource; 
      string userID = builder.UserID; 
      string pass = builder.Password; 

      crConnectionInfo.ServerName = dbDataSource; 
      crConnectionInfo.DatabaseName = dbName; 
      crConnectionInfo.UserID = userID; 
      crConnectionInfo.Password = pass; 

      Tables Crtables; 
      Crtables = cryRpt.Database.Tables; 

      foreach (CrystalDecisions.CrystalReports.Engine.Table CrTable in Crtables) 
      { 
       crtableLogoninfo = CrTable.LogOnInfo; 
       crtableLogoninfo.ConnectionInfo = crConnectionInfo; 
       CrTable.ApplyLogOnInfo(crtableLogoninfo); 
      } 

      frm.crystalReportViewer1.ReportSource = cryRpt; 
      frm.crystalReportViewer1.RefreshReport(); 

      Cursor = Cursors.Arrow; 
      frm.Show(); 
     } 
     catch (Exception ex) 
     { 
      MessageBox.Show(ex.Message, "Error", MessageBoxButtons.OK, MessageBoxIcon.Error); 
     } 
} 

ので、いずれかがその時「btn_previewdocument_Clickで「プレビュードキュメント」ボタンをクリックすると、ボタンのクリックイベントで私のコード"イベントが発生します。

このイベントでは、クリスタルレポートで表示したいクエリーデータに応じてこの処理を行いたいと思います。

アドバンスありがとうございました。

これを試してください。前にfrm.crystalReportViewer1.ReportSource = cryRpt;を追加します。cryRpt.Refresh();
