        '	Clear the existing list
        Me.UltraComboEditor1.Items.Clear()

        '	Add 5 new items to the list
        Me.UltraComboEditor1.Items.Add(1, "One")
        Me.UltraComboEditor1.Items.Add(2, "Two")
        Me.UltraComboEditor1.Items.Add(3, "Three")
        Me.UltraComboEditor1.Items.Add(4, "Four")
        Me.UltraComboEditor1.Items.Add(5, "Five")

        '	Make the first item in the list the SelectedItem
        Me.UltraComboEditor1.SelectedIndex = 0

        '	Use the DropDown method to programmatically make
        '	the list portion appear
        Me.UltraComboEditor1.DropDown()

    Private Sub UltraComboEditor1_SelectionChanged(ByVal sender As Object, ByVal e As System.EventArgs) Handles UltraComboEditor1.SelectionChanged
        '	If the last item in the list was selected, use the CloseUp method
        '	to programmatically hide the list portion
        If (Me.UltraComboEditor1.SelectedIndex = (Me.UltraComboEditor1.Items.Count - 1)) Then
            Me.UltraComboEditor1.CloseUp()
        End If

    End Sub
