你可以通過單獨用代碼綁定子報表來解決這個問題。

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 有三個字報表,dataSet 有三個表。
上述代碼通過訪問每個字報表,來實現子報表資料繫結
