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;
    }

The correct way to achieve this is to edit the theme you are using using the Visual Style Builder tool.

The other approach is to use code to override the theme values .
