Aca del dejo como crear un TreeView en GKT#, bajo monodevelop 5.10 Linux aunque tambien funciona para Xamarin Studio sin problemas
Librerias a Usar

using Gtk;
using Gdk;
using Glade;
using Npgsql;
using System.Collections;
using System.Data;

Explicacion del arreglo

2 ancho de la columna
3 R Color
4 G Color
5 B Color
6 true visualiza columna false oculta columna
void crea_treeview()
{
object[] parametros = { treeview_concepto_remis,treeViewEngineconcepremis};
string[,] coltreeview = {
{ "Cant.", "text","","","","","true"},
{ "Ref.", "text","","","","","true" },
{ "Descripcion", "text","400","","","","true" },
{ "Pre. Unitario", "text","","","","","true" },
{ "Total", "text","","","","","true" },

{ "Cod. Barra", "text","","","","","true" },
{ "Ref.", "text","","","","","true" },
{ "ID Producto", "text","","","","","true" },
{ "Nro.remision", "text","","","","","false" }
};
crea_colums_treeview (parametros, coltreeview,"treeview_concepto_remis");
}
