With that I get an error that there is no method "model"
Here is the snippet:

static void CellEdit (object o, Gtk.EditedArgs args)
	{
		TreeIter iter;
		TreePath path = new TreePath(args.Path);
		store.GetIter(out iter, path);
		//store.SetValue(iter, 0, args.NewText);
		string storestring = store.NColumns.ToString();
		Console.WriteLine(storestring);
		string iterstring = iter.ToString();
--------------------------------------------------------------------------		
When I debug there I can see that path holds the rownumber an NColumns
holds the total count of all columns available not the specific one
where I made the changes.
