ASP.NET怎样传参数到水晶报表里面的子报表?在线等!
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!


PS:这是第二个账号发的同一条问题,都是100分.大家帮帮忙.总共有200分!谢谢!

------解决方案--------------------
myReportDoc.DataDefinition.ParameterFields[ "DepartmentCode "].ApplyCurrentValues(pvDepartmentID);//這是主報表的

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

可以這樣定義：
ParameterFieldDefinitions parameterFieldDefinitions = reportDocument.DataDefinition.ParameterFields;
ParameterFieldDefinition parameterFieldDefinition = parameterFieldDefinitions[SUBREPORT_PARAMETER_FIELD_NAME, SUBREPORT_NAME];



------解决方案--------------------
只给主报表用程序传过，子报表都是通过主报表传参过去。

LS那位能解决么？不能的话就用主报表向子报表传参，不就是多给主报表传个参数而已么
