Buttons- Return to beginning and End of a Text File

I have a phone book program that I created in visual basic and I want a button to return to the beginning of all the entries and one button to go to the very last entry. How would I do that?

So far I have this, but I don't think it works properly
Private Sub BtnFirst_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles BtnFirst.Click
        If Index = Count Then
            Index = Index - Count + 1
            DisplayData()
        End If
    End Sub

    Private Sub BtnLast_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles BtnLast.Click
        If Index < Count Then
            Index = Index + Count - 1
            DisplayData()
        End If
    End Sub


Thanks :)
