I am using two subreports in Crystal Reports. I am using following coding for set datasource for the subreport. The main report will come. But the subreport is not displaying. Please anybody help me.

C#

rptdoc.SetDataSource(ds.Tables[0]);
rptdoc.Subreports[0].SetDataSource(ds2.Tables[0]);
rptdoc.Subreports[1].SetDataSource(ds3.Tables[0]);

And also I tried this following code, the error displays "the object reference is not to an instance of an object"

rptdoc.OpenSubreport("SALESTRANSACTION").SetDataSource(ds2);
rptdoc.OpenSubreport("RECEIPTTRANSACTION").SetDataSource(ds2);
