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？这也是我另一文章所说的问题

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
