button view

frmView view = new frmView();
            view.vSeries = txtSeries.Text;
           
            view.Show();
            view.Location = new Point(0, 50);


            DataTable dt = new DataTable();
            dt = objPaymentBL.fnGetPayReg(DTFROM, DTTO);

 view.DTFROM.Text = DtpDateFrom.Value.Date.ToString() + "TO" + DtpDateTo.Value.Date.ToString();


BL
DateTime dRPDate;
        DateTime FROM;
        DateTime TO;

public DateTime DTFROM
