Answer 1

I found one solution, I had to create two events for my RadTreeView.

enter code here
    private void RadTV_Menu_Principal_NodeMouseEnter(object sender, RadTreeViewEventArgs e)
    {
        ///Paint Node when begining focus
        e.Node.BackColor = Color.LightSteelBlue;
        e.Node.GradientStyle = GradientStyles.Solid;
    }

    private void RadTV_Menu_Principal_NodeMouseLeave(object sender, RadTreeViewEventArgs e)
    {
        ///Return the initial color when leave focus
        e.Node.BackColor = SystemColors.Highlight;
    }
