// ON BUTTON CLICK I WROTE THIS

 private void btnprint_Click(object sender, EventArgs e)
        {
            this.Sales_InfoTableAdapter.FillByid(this.DataSet1.Sales_Info, int.Parse(textBox1.Text));

            this.reportViewer1.RefreshReport();

            LocalReport localReport = new LocalReport();
            localReport.ReportPath = Application.StartupPath + "\\Report1.rdlc";
            localReport.PrintToPrinter();
