For Each ....

No, the order isn't customizable with for each. You can iterate through the collection by index however you'd like. For example, you can use a For loop:

        Dim buttons = g1.Children.OfType(Of Button)()
        Dim startAt As Integer = 5
        Dim numButtons = buttons.Count
        For i As Integer = 0 To numButtons - 1
            Debug.WriteLine(buttons((startAt + i) Mod numButtons).Content.ToString())
        Next
