            DataSet a = new DataSet();

            DataTable dtbl = new DataTable("DataTable1");

            SqlDataAdapter adp = new SqlDataAdapter();

            adp.SelectCommand = new SqlCommand();

            adp.SelectCommand.Connection = con;

            adp.SelectCommand.CommandText = "Report";

            adp.SelectCommand.CommandType = CommandType.StoredProcedure;

            adp.SelectCommand.Parameters.AddWithValue("@clrk_Name", name.Text);

            adp.SelectCommand.Parameters.AddWithValue("@clrk_Family", family.Text);

            adp.SelectCommand.Parameters.AddWithValue("@clrk_MelliCode", melli.Text);

            SqlDateTime az_d = SqlDateTime.Parse(az.Text);

            adp.SelectCommand.Parameters.AddWithValue("@AzTarikh", az_d);

            SqlDateTime ela_d = SqlDateTime.Parse(ela.Text);

            adp.SelectCommand.Parameters.AddWithValue("@Ela", ela_d);

            adp.Fill(a, "DataTable1");

            Form1 f1 = new Form1();

            ReportDataSource source = new ReportDataSource("datatable1", dtbl);

            f1.reportViewer1.Visible = true;

            f1.reportViewer1.ProcessingMode = ProcessingMode.Local;

            f1.reportViewer1.LocalReport.ReportPath = "Report1.rdlc";

            f1.reportViewer1.LocalReport.DataSources.Clear();

            f1.reportViewer1.LocalReport.DataSources.Add(source);
