WinForm Menu firing Form switching practices

Often use similar to the WinForm form, where click on the menu when the Netural do the content form switch, today also record the method of switching

Place a panal in the main form, and all the content forms are rendered on panal, implementing the following methods

Instantiating the main form

private void Frmsetup_load (object sender, EventArgs e)
{
This.btnsystem_click (null, NULL);
}

Initialize the content form

Public Frmsetup (UINT UIDEVICESN)
: This ()
{
M_UIDEVICESN = UIDEVICESN;
M_devsetuprefobj = new Devsetuprefobj (M_UIDEVICESN);
String sinipath = this.m_uiDeviceSN.ToString ("D08") + "\\Setup\\Setup.ini";
if (file.exists (Sinipath))
{
M_devsetuprefobj.loadlocalsetup (Sinipath);
}
Else
{
M_devsetuprefobj.loaddevicesetup ();
}

M_frmbasesyssetup = new Frmbasesystemsetup (M_UIDEVICESN, m_devsetuprefobj);
M_frmeditsetup = new Frmeditsetup (M_UIDEVICESN, m_devsetuprefobj);
M_frmprintsetup = new Frmprintsetup (M_UIDEVICESN, m_devsetuprefobj);
M_frmusersetup = new Frmusersetup (M_UIDEVICESN, m_devsetuprefobj);
M_frmmoresetup = new Frmmoresetup (M_UIDEVICESN, m_devsetuprefobj);
M_frmregister = new Frmregister (M_UIDEVICESN, m_devsetuprefobj);
}
Instantiating a content form
Frmbasesystemsetup M_frmbasesyssetup;
Frmeditsetup M_frmeditsetup;
Frmprintsetup M_frmprintsetup;
Frmusersetup M_frmusersetup;
Frmmoresetup M_frmmoresetup;
Frmregister M_frmregister;

private void Btnsystem_click (object sender, EventArgs e)
{
This. Showsystem ();
This. Hideedit ();
This. Hideprint ();
This. Hideuser ();
This. Hidemore ();
This. Hideregister ();
}

Form Toggle

private void Showuser ()
{
PnlShow.Controls.Clear ();

M_frmusersetup.toplevel = false;
M_frmusersetup.formborderstyle = System.Windows.Forms.FormBorderStyle.None;
PNLSHOW.CONTROLS.ADD (M_frmusersetup);

This.m_frmUserSetup.ShowForm ();
}

The above is the general idea.
