Dynamic Radio Button Ordering: How to?

Help. I am trying to develop a content management system. One of the things I am attempting to do is to draw a list of links from the database and display them as radio buttons so that I can select one and move it up and down in the order. Seems to work fine for moving up, but when I move it down the second time, it is moving the top item in the list down one rather than the selected item. Can anyone offer suggestions to clean up the code and make it work, please. I have tried several variations, all with the same result. This is the latest:

VB Code:

Private Sub Page_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Load
        If Not IsPostBack Then
            Dim sQuery As String
            Dim connection As New OleDbConnection(myConnString)
            Dim command As OleDbCommand
            Dim i As Integer = 0
            sQuery = "Select * from tblLinks order by intPosition ASC"
 
            connection.Open()
            command = New OleDbCommand(sQuery, connection)
            Dim objReader As OleDbDataReader = command.ExecuteReader
            Dim btnList As New RadioButtonList
            While objReader.Read
                i = i + 1
                btnList.Items.Add(New ListItem(objReader.Item("txtValue"), objReader.Item("intPosition")))
            End While
            btnList.ID = "btnList"
            pnlTest.Controls.Add(btnList)
            Session.Add("Buttons", btnList)
            Session.Add("NumLinks", i)
            objReader.Close()
        connection.Close()
        End If
    End Sub
 
    Private Sub btnUp_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles btnUp.Click
        moveLinks(CInt(Request.Item("btnList").ToString) - 1, True)
    End Sub ' ' btnUp_click
 
    Private Sub btnDown_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles btnDown.Click
        moveLinks(CInt(Request.Item("btnList").ToString) - 1, False)
    End Sub ' btnDown_click
 
    Private Sub moveLinks(ByVal id As Integer, ByVal up As Boolean)
        Dim i As Integer
        Dim top As Integer
        Dim bottom As Integer
        Dim switchFrom As Integer
        Dim switchTo As Integer
        Dim selected As Integer
        Dim dir As Integer
        Dim btnList As New RadioButtonList
        Dim size As Integer = Session.Item("NumLinks") - 1
 
 
 
        btnList = Session.Item("Buttons")
 
        If (up And id > 0) Or (Not (up) And id < size) Then
 
            Dim newList As New RadioButtonList
            Dim tmp As String
 
            switchTo = id
 
            If up Then
                top = 0
                bottom = size
                dir = 1
                switchFrom = id - 1
            Else
                top = size
                bottom = 0
                dir = -1
                switchFrom = id + 1
            End If
            selected = switchFrom
 
            For i = top To bottom Step dir
                If i = switchFrom Then
                    tmp = btnList.Items(switchTo).Text
                    Add(newList, tmp, switchTo, dir)
                    tmp = btnList.Items(switchFrom).Text
                    Add(newList, tmp, switchFrom, dir)
                    i = i + dir
                Else
                    tmp = btnList.Items(i).Text
                    Add(newList, tmp, i, dir)
                End If
            Next
 
            pnlTest.Controls.Clear()
 
            newList.Items(selected).Selected = True
            newList.ID = "btnList"
            pnlTest.Controls.Add(newList)
 
            Session.Remove("Buttons")
            Session.Add("Buttons", newList)
            newList.Dispose()
        End If
 
    End Sub
 
    Private Sub Add(ByRef tmp As RadioButtonList, ByVal txt As String, ByVal num As Integer, ByVal dir As Integer)
        If dir > 0 Then
            tmp.Items.Add(New ListItem(txt, num))
        Else
            tmp.Items.Insert(0, New ListItem(txt, num))
        End If
    End Sub
