The rectangular area above the panel to catch mouse inputs

Question

C # winforms here. I need to draw an invisible area of ​​the rectangle above the panel and catch his mouse to enter / leave events.

My situation (as with some other suggestions you may have):

I have a media player (panel), when I enter the mouse I make a small navigation menu visible (it is located above the panel). I want to hide the navigation menu with the mouse out of the panel. This works, but, unfortunately, entering the navigation menu makes it invisible. Many thanks.

When moving away from the mouse, just see if Cursor.Positionyour current rectangle contains . For example, using the panel and label:

    public Form1()
    {
        InitializeComponent();
        panel1.MouseEnter += panel1_MouseEnter;
        panel1.MouseLeave += common_MouseLeave;
        label1.MouseLeave += common_MouseLeave;
    }

    private void panel1_MouseEnter(object sender, EventArgs e)
    {
        label1.Visible = true;
    }

    private void common_MouseLeave(object sender, EventArgs e)
    {
        Rectangle rc = panel1.RectangleToScreen(panel1.ClientRectangle);
        if (!rc.Contains(Cursor.Position))
        {
            label1.Visible = false;
        }
    }
