Declaration

DateTime DTFROM;
DateTime DTTO;
string vSeries;

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
{
get { return FROM; }
set { FROM = value; }
}
public DateTime DTTO
{
get { return TO; }
set { TO = value; }
}
public DataTable fnGetPayReg(string vSeries,DateTime FROM, DateTime TO)
{
DataTable dt = new DataTable();
dt = objPaymentMasterDL.fnGetPayReg(vSeries,DTFROM, DTTO);
return dt;
}

DL

public DataTable fnGetPayReg(string vSeries,DateTime FROM, DateTime TO)
{
DataTable dt = new DataTable();
dt = objPaymentMasterDL.fnGetPayReg(vSeries,DTFROM, DTTO);
return dt;
}

DateTime DATEFROM;
DateTime DTTO;

public DateTime FROM
{
get { return DATEFROM; }
set { DATEFROM = value; }
}
public DateTime TO
{
get { return DTTO; }
set { DTTO = value; }
