水晶报表中子报表的数据绑定问题

是否被水晶报表中子报表的数据绑定问题折磨过？该死的 LogonException 这也是我上一文章所说的问题

你可以通过单独用代码绑定子报表来解决这个问题。

string sConnectionString = ConfigurationSettings.AppSettings["dbCommISMS"];
   
   SqlConnection sqlConn = new SqlConnection(sConnectionString);
   SqlCommand sqlComm = new SqlCommand();
   SqlDataAdapter dataAdapter = new SqlDataAdapter();

   sqlConn.Open();

   sqlComm.Connection = sqlConn;
   sqlComm.CommandType = CommandType.Text;

   dataAdapter.SelectCommand = sqlComm;

   Dataset1 dataSet = new Dataset1();

   string sSQL = "SELECT * FROM T_REQUEST WHERE APPLI_ID = '" + appli_id + "'";

   sqlComm.CommandText = sSQL;
   dataAdapter.Fill(dataSet, "T_REQUEST");

   sSQL = "SELECT * FROM T_REQUEST_INSPECTION WHERE APPLI_ID = '" + appli_id + "'";

   sqlComm.CommandText = sSQL;
   dataAdapter.Fill(dataSet, "T_REQUEST_INSPECTION");

   sSQL = "SELECT * FROM T_ACCEPT_INSPECTION WHERE APPLI_ID = '" + appli_id + "'";

   sqlComm.CommandText = sSQL;
   dataAdapter.Fill(dataSet, "T_ACCEPT_INSPECTION");

   SubreportObject oSubreport1 = oRpt.ReportFooterSection1.ReportObjects["Subreport1"] as SubreportObject;
   ReportDocument oSub1 = oSubreport1.OpenSubreport("Inspection");

   oSub1.SetDataSource(dataSet);

   SubreportObject oSubreport2 = oRpt.ReportFooterSection2.ReportObjects["Subreport2"] as SubreportObject;
   ReportDocument oSub2 = oSubreport1.OpenSubreport("Survey");

   oSub2.SetDataSource(dataSet);

   SubreportObject oSubreport3 = oRpt.ReportFooterSection2.ReportObjects["Subreport3"] as SubreportObject;
   ReportDocument oSub3 = oSubreport1.OpenSubreport("Allonge");

   oSub3.SetDataSource(dataSet);

   oRpt.SetDataSource(dataSet);

   oViewer.ReportSource = oRpt;

oRpt 有三个字报表，dataSet 有三个表。
上述代码通过访问每个字报表，来实现子报表数据绑定
