Why Showing all records ?

I am creating a Crysal Report,, by using Wizard.

In wizard, i have set columns, group by

Now, i have called Stored Procedure and passed some parameters, 

returned resuilts get stored in DataSet 

by debuging i have checked Dataset results, results are correct(what i needed using filters)  

now i am setting DataSource

rptDoc.Load(Server.MapPath("reports/ReportStock.rpt"));

rptDoc.SetDataSource(dsDataSource);
CrystalReportViewer1.ReportSource = rptDoc;

but report is showing all records instead of showing some records.

What i am doing wrong ???
