   myLabel.Text = "Header Text for each column: <br>";

   for ( int i = 0; i < myGrid.Columns.Count; i ++ ) {
      myLabel.Text += myGrid.Columns [ i ] .HeaderText + "<br>";
   }
}

Sub Button_Click ( src As Object, e As EventArgs )
   myLabel.Text = "Header Text for each column: <br>"
   Dim i As Integer
   For i = 0 To myGrid.Columns.Count - 1
      myLabel.Text &= myGrid.Columns ( i ).HeaderText & "<br>"
   Next i
End Sub
