-Smart30

You should have to store these data into a Dictionary<string,List<string> and use data-binding technique to assign List<T> to comboBox2 of selected Key of ComboBox1.

Sample:

 Dim data As New Dictionary(Of String, List(Of String))
 data.Add("Select", New List(Of String))
 data.Add("First", New List(Of String) From {"A", "B", "C"})
 data.Add("Second", New List(Of String) From {"P", "Q"})

 ComboBox1.DataSource = data.Keys.ToList()
 AddHandler ComboBox1.SelectedIndexChanged, 
      Sub(sa, ea)
          ComboBox2.DataSource = data(ComboBox1.Text)
      End Sub
