How allows ShowDialog in child of MdiContainer?

I have a form that this.IsMdiContainer = true. I show a child form in it.

 FrmCustomer frm=new FrmCustomer();
 frm.MdiParent = this;
 frm.Show();

I want to showdialog a form in FrmCustomer . I use this code,

  FrmCustomerDetail frm=new FrmCustomerDetail(null);
  frm.MdiParent = this.MdiParent;
  frm.ShowDialog();

but i get error,

Form that is not a top-level form cannot be displayed as a modal dialog box. Remove the form from any parent form before calling showDialog.'

One way to do this would be to leave our the MdiOwner and set the Window Owner using ShowDialog method parameter. 

   FrmCustomerDetail frm=new FrmCustomerDetail(null);
   frm.ShowDialog(this);
