  In the SelectedIndexChanged event for the first ComboBox add code similar to the following:

  If ComboBox1.SelectedItem = "Green" Then

  ComboBox2.SelectedItem = "Yellow"

  Else

  ComboBox2.SelectedItem = "Red"

  End If

  For a large number of items, you could use a Select Case statement instead.

  Hope this helps,

  If I understand you correctly, the following should do the trick - this example assumes that the first ComboBox has items named "One" and "Two".

  Private Sub ComboBox1_SelectedIndexChanged(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles ComboBox1.SelectedIndexChanged

  Dim list1 As New List(Of String)

  list1.Add("1")

  list1.Add("2")

  list1.Add("3")

  Dim list2 As New List(Of String)

  list2.Add("X")

  list2.Add("Y")

  list2.Add("Z")

  Dim i As Integer

  Select Case ComboBox1.SelectedItem

  Case "One"

  ComboBox2.Items.Clear()

  For i = 0 To list1.Count - 1

  ComboBox2.Items.Add(list1.Item(i))

  Next

  Case "Two"

  ComboBox2.Items.Clear()

  For i = 0 To list2.Count - 1

  ComboBox2.Items.Add(list2.Item(i))

  Next

  End Select

  End Sub

  sorry but no i didn't explain myself properly, i meant

  have about 27 lists of choices for drop down 2

  so if option 1 (numbers/symbols) then the 1st list would be searchable in drop down 2 or if option 2 (A) was chosen then the 2nd list would be loaded into drop down 2
