body: <p>How can I show a child form within a mdi container form which its windowstate= maximized ?</p>
  
  <p>when I put these below lines of code when my child form is loading (by clicking on a menu Item of my Main form), the child form loses its parent position and does not show within its parent form.</p>
  
  <pre><code>private void mnuUnit_Click(object sender, EventArgs e)
  {
      frmUnit frm = new frmUnit();
      frm.MdiParent = this;
      frm.WindowState = FormWindowState.Maximized;
      frm.Show();
  }
  </code></pre>
