Have a public static variable in the orderenter form,Find the opended orderenter by like this
Use FormCollection class to get the openned form object.

C#

FormCollection fc = Application.OpenForms;
foreach (Form frm in fc)
{
  if(frm.name=="orderenter")
{
frm.Myvalue= customerdetails;

}
}

or
Have public static method in orderenter and pass the value as parameter

C#

FormCollection fc = Application.OpenForms;
foreach (Form frm in fc)
{
  if(frm.name=="orderenter")
{
frm.showform(customerdetails);
}

// In the orderenter form have show showform method
public static void showform(customerdetails)
{
txtcustomercode.Text =customerdetails;
}

}

As I understand,
Form1 ---> Form2 (now when it close pass result to already opened form1 again)

you should do this in your form2

-> In form2 (in which you have write methoddeclare form level public variables Return_Cust_code,Return_Cust_Nm
-> now set that variables in form close method instead of that new form opening code you have mention in question

C#

Return_Cust_code = dataGridView1.CurrentRow.Cells[0].Value.ToString();
Return_Cust_Nm = dataGridView1.CurrentRow.Cells[1].Value.ToString();
this.DialogResult= Dialogresult.ok;
this.Close();

-> now in Form1 receive these varibles like this

C#

Form1 frm = new Form1();
if (frm.ShowDialog() == Dilogresult.OK)
{
   string cc = frm.Return_Cust_code;
   string cn = frm.Return_Cust_Nm;
}

Happy Coding!
