combo boxs

Hello,

you can handle the SelectionChanged event of your first comboBox :

Private Sub firstComboBox_SelectionChanged(
              sender As Object, e As EventArgs)
  Select Case firstComboBox.SelectedIndex
    Case 0
      '// do something when item 0 is selected
    Case 1
      '// do something when item 1 is selected
    Case 2
      '// do something when item 2 is selected
    Case 3
      '// do something when item 3 is selected
  End Select
End Sub
