You need something like this:-

VB

<pre>
Function LookForControl(ByVal controlName As String) As Control

        Dim x As Control = Nothing
        For Each ctl As Control In Me.Controls
            If ctl.Name = controlName Then
                x = ctl
                Return ctl
            ElseIf ctl.HasChildren Then
                x = LookForControl(controlName)
            End If
            If x IsNot Nothing Then
                Return x
            End If
        Next

        Return Nothing

    End Function

1 dont forget to name your controls
2 name them uniquely
