Hi,

I have a Crystal Report which has two sub reports in it. When I try to
view this Crystal Report in my report preview , it is showing data for sub
reports also. But when I run it and view the Crystal
Report I am not able to view the data of sub reports. It is not giving any
error. It is not showing the data. I am not knowing what might be
the problem. Please let me know if you have any idea

pls help me i really need it
thankyou

//ds1 is the dataset of main report
//ds2 is the dataset of sub report
//dt1 is the table of main report
//dt2 is the table of sub report
    ds1.Tables.Add(dt1);
    ds2.Tables.Add(dt2);

    ds1.WriteXmlSchema("sample1.xml");
    ds2.WriteXmlSchema("sample2.xml");


    //transefer data to crystalreportviewer
    CrystalReport1 cr1 = new CrystalReport1();//main report
    CrystalReport2 cr2 = new CrystalReport2();//sub report

    cr1.SetDataSource(ds1);
    cr2.SetDataSource(ds2);

    crystalReportViewer1.ReportSource = cr1;
