Delete Bindings

[BobBob10]

How do I delete the bindings from a list box. My code fails at:

 Dim i As Integer = objAddTo.Items.Count
        Dim SortListA As ArrayList
        Dim j As Integer

        Do While i > 0
            If objAddTo.Items.Item(i - 1).Selected = True Then
                Me.objRemoveFrom.Items.Add(Me.objAddTo.Items.Item(i - 1))
                objAddTo.Items.Remove(objAddTo.Items.Item(i - 1))
                'Sort list boxes
                SortListA = New ArrayList
                'Me.objRemoveFrom.DataSource = SortListA
                For j = 0 To objRemoveFrom.Items.Count - 1
                    SortListA.Add(objRemoveFrom.Items(j).Value)
                Next 'j
                objRemoveFrom.DataSource = SortListA
'Fails here 
                objRemoveFrom.DataBind()
                Session("SortA") = SortListA
                Session("SortA").sort()
            End If
            i -= 1
        Loop

my code fails as the list box is already binded.

How do I clear this to create a new binding so that my list box will sort?

What error do you get?

Ok sorted it

Would you like to explain how in case any future readers come across the same problem (it also means you are giving something back to Tek-Tips)?

OK:

        Dim i As Integer = objAddTo.Items.Count
        Dim SortListA As ArrayList
        Dim j As Integer
        Dim k As Integer

        Do While i > 0
            If objAddTo.Items.Item(i - 1).Selected = True Then
                Me.objRemoveFrom.Items.Add(Me.objAddTo.Items.Item(i - 1))
                objAddTo.Items.Remove(objAddTo.Items.Item(i - 1))
                'Sort list boxes
                SortListA = New ArrayList
                For j = 0 To objRemoveFrom.Items.Count - 1
                    SortListA.Add(objRemoveFrom.Items(j).Value)
                Next 'j
                SortListA.Sort()
                objRemoveFrom.Items.Clear()
                For k = 0 To SortListA.Count - 1
                    Me.objRemoveFrom.Items.Add(SortListA.Item(k))
                Next 'k
            End If
            i -= 1
        Loop

I basically created an Array and sorted that array. Cleared the list box and populated with new Array.
