晶體報告問題

Question

我有下面的代碼來傳遞參數打開crsytal報告。但是當它打開水晶報告時，我再次詢問參數以顯示報告。

 ReportDocument cryRpt = new ReportDocument(); 
     TableLogOnInfos crtableLogoninfos = new TableLogOnInfos(); 
     TableLogOnInfo crtableLogoninfo = new TableLogOnInfo(); 
     ConnectionInfo crConnectionInfo = new ConnectionInfo(); 
     Tables CrTables; 
     cryRpt.Load(Server.MapPath("DMTR1.rpt")); 
     crConnectionInfo.ServerName = m_strConnectionString.Split(';')[0].Split('=')[1]; 
     crConnectionInfo.DatabaseName = m_strConnectionString.Split(';')[1].Split('=')[1]; 
     crConnectionInfo.UserID = m_strConnectionString.Split(';')[2].Split('=')[1]; 
     crConnectionInfo.Password = m_strConnectionString.Split(';')[3].Split('=')[1]; 
     CrTables = cryRpt.Database.Tables; 
     foreach (CrystalDecisions.CrystalReports.Engine.Table CrTable in CrTables) 
     { 
      crtableLogoninfo = CrTable.LogOnInfo; 
      crtableLogoninfo.ConnectionInfo = crConnectionInfo; 
      CrTable.ApplyLogOnInfo(crtableLogoninfo); 
     } 
     cryRpt.SetParameterValue("@ReceivedDate", Convert.ToDateTime("06/21/2013")); 
     cryRpt.SetParameterValue("@TransferDate", Convert.ToDateTime("08/21/2013")); 
     crysview.ReportSource = cryRpt; 
     crysview.RefreshReport(); 

Answer 1

您需要用crysview.DataBind();替換crysview.RefreshReport();。
