    Have you added :

    this.FormClosing += new System.Windows.Forms.FormClosingEventHandler(this.frmMain_FormClosing);
    

    (automatically added when you double-click in the Designer)

    Try the following

    Paste into form

    const int WM_CONTEXTMENU = 0x007B;  
    protected override void WndProc(ref Message m)  
    {  
        if (m.Msg == WM_CONTEXTMENU)  
        {  
            m.Result = IntPtr.Zero;  
            Close();  
        }  
        else  
        {  
            base.WndProc(ref m);  
        }  
    }  
    

    In the form constructor

    Type Closing += press TAB which should give you an event e.g. where I added a MessageBox

    Once you have right clicked the MessageBox is shown then the form closes.
