To select rows spanning the entire width of RadTreeView (rather than just the node label), set the FullRowSelect property to true and ShowLines to false. In addition you can set the alternating row color by setting the AllowAlternatingRowColor and AlternatingRowColor properties.

radTreeView1.TreeViewElement.AllowAlternatingRowColor = true;
radTreeView1.TreeViewElement.AlternatingRowColor = Color.LightBlue;

RadTreeView1.TreeViewElement.AllowAlternatingRowColor = True
RadTreeView1.TreeViewElement.AlternatingRowColor = Color.LightBlue
