         :

     DataGridView grid = new DataGridView { Name = "Tom" };

     grid.BindingContext = new BindingContext();
     grid.DataSource = dataTable;

     int n1 = grid.Columns.Count; // returns three
  }

Curiously enough, the order in which you set the binding context or the data source appears not to matter !
