DataSet myDataSet = new DataSet();
ReportDocument myReport = new ReportDocument();
string ShipCountry;
ShipCountry = tbShipCountry.Text;
myDataSet.Merge(ws1.LoadReport(ShipCountry));
dataGrid1.DataSource = myDataSet.DefaultViewManager ;
myReport.Load("CrystalReport1.rpt");
myReport.SetDataSource(myDataSet);

crystalReportViewer1.ReportSource = myReport;
}

public DataSet LoadReport(string ShipCountry)
{
DataSet ds;
ds = new DataSet();
sqlDataAdapter1.SelectCommand.Parameters["@ShipCountry"].Value = ShipCountry;
sqlDataAdapter1.Fill(ds);
