关于从程序传递参数到水晶报表的子报表的问题,谢谢!
1.主报表和子报表都有一个参数,此参数在创建报表数据源时已经创建.主报表的参数名为:DepartmentCode,子报表的参数名为:Chiefi
2.主报表的参数我能够传,代码如下:
-------------------------------
private void ConfigurCrystalReports()
{
ReportDocument myReportDoc = new ReportDocument();
string reportPath = Server.MapPath( "../Reports/rp_Total.rpt ");
myReportDoc.Load(reportPath);
TableLogOnInfo logonInfo = new TableLogOnInfo();

foreach(CrystalDecisions.CrystalReports.Engine.Table tb in myReportDoc.Database.Tables)
{
logonInfo = tb.LogOnInfo;
logonInfo.ConnectionInfo.ServerName = "TestServer ";
logonInfo.ConnectionInfo.DatabaseName = "TestDB ";
logonInfo.ConnectionInfo.UserID = "sa ";
logonInfo.ConnectionInfo.Password = "test ";
tb.ApplyLogOnInfo(logonInfo);
}

ParameterValues pvDepartmentID = new ParameterValues();
ParameterDiscreteValue pdDepartmentID = new ParameterDiscreteValue();
pdDepartmentID.Value = " '0000200027 ', '0000200028 ' ";
pvDepartmentID.Add(pdDepartmentID);
myReportDoc.DataDefinition.ParameterFields[ "DepartmentCode "].ApplyCurrentValues(pvDepartmentID);

myCrystalReportViewer.ReportSource = myReportDoc;
}
-------------------------------
3.问题:怎么给子报表的参数Chiefi传递参数呢?谢谢!

[解决办法]
更改子报表链接里面

可以设置参数



[解决办法]
myReportDoc.DataDefinition.ParameterFields[ "DepartmentCode "].ApplyCurrentValues(pvDepartmentID);//是主表的

myReportDoc.DataDefinition.ParameterFields[子表字段名,子表名].ApplyCurrentValues(......);//是子表的
