问题描述

我创建了一个报告并尝试加载到我的网络表单

  <   td  >  
 
 
 
 <   CR：CrystalReportViewer     ID   =  CrystalReportViewer1      runat   =  server  
                      < span class =code-attribute>                   AutoDataBind   =  True    GroupTreeImagesFolderUrl   =    高度  =  1202px  
                                         ReportSourceID   =  CrystalReportSource1    ToolbarImagesFolderUrl   =    
                                         ToolPanelWidth   = < span class =code-keyword> 200px   宽度  =  1104px    /  >  
 <   CR：CrystalReportSource     ID   =  CrystalReportSource1      runat   =  server >  
 <  < span class =code-leadattribute>报告    FileName   =  Gp.rpt >  
 <   / Report  >  
 <   / CR：CrystalReportSource  >  
 <  < span class =code-leadattribute> / td  >  
 

点击按钮我试图设置数据源。

  Dim  dt  As  新 DataTable 
 startDate = txtStart.Text.Trim（）
 endDate = txtEnd.Text.Trim（）
 dt = BO.GenerateGrossProfit（startDate，endDate）
 
  Dim  rptA  As  ReportDocument = 新 ReportDocument（）
 
 
 '  //  
  Dim  str 作为 字符串 =    
  Dim  ds 作为 新 DataSet 
 str =  从Report_HDR_History中选择ID，BRANCHCODE 
 ds = DL.ExecuteNonQueryforGP（str）
 rptA.Load（Server.MapPath（ ）&   / Gp.rpt）
 rptA.FileName = Server.MapPath（  / Gp.rpt）
 rptA.SetDataSource（ds.Tables（ 0 ））
 rptA.SetDatabaseLogon（  SMUSER ，  SMUser @ 123）
 CrystalReportViewer1.DisplayToolbar =  True  
 CrystalReportViewer1.ReportSource = rptA 
 CrystalReportViewer1.DataBind（）
 CrystalReportViewer1.RefreshReport（）

没有显示错误，但我的报告查看器没有数据..
