Is it possible that instead ContextMenuStrip of NotifyIcon, display a Form, which will behave like ContextMenuStrip?

Question

I want to replace ContextMenuStrip of NotifyIcon with some more complex Form. I can display form when user click on NotifyIcon in SystemTray but I can't hide/close form like ContextMenuStrip close when user click somewhere else.

Is that possible?

Here is example code, I Show that form this way:

private void Mouse_Up_Event(object sender, MouseEventArgs e)
{  
    FormMenu f = new FormMenu();
    f.StartPosition = System.Windows.Forms.FormStartPosition.Manual;
    f.SetDesktopLocation(Cursor.Position.X - f.Width / 2,
        Cursor.Position.Y - f.Height - 20);
    f.Show();
    f.Focus();
}

And FormMenu is a complex form with panels and multiple buttons.

You can host your complex control or form in ContextMenuStrip using ToolStripControlHost.

Code:

var c= new MyUserControl();
//Set up properties and events then add it to context menu
this.contextMenuStrip1.Items.Add(new ToolStripControlHost(c));

You can also add your form to context menu strip this way:

var f = new YourForm() { 
    TopLevel = false, 
    FormBorderStyle = System.Windows.Forms.FormBorderStyle.None, 
    MinimumSize= new Size(200, 200), /*Your preferred size*/
    Visible=true
};
//Set up properties and events then add it to context menu
this.contextMenuStrip1.Items.Add(new ToolStripControlHost(f) );

Screenshot:

In above screenshot I added a form to a context menu strip that has not other items and set ShowImageMargin property of context menu to false.

You can also have other Items and sub menus.
