    Hello Max,

    In order to get the data from the item/items transferred in the code-behind, you have to set the source ListBox' AutoPostBackOnTransfer property to true and in the control's OnTransferred server-side event handler you can access the collection (e.Items) of transferred items and each item in it by index:
    Protected Sub RadListBox1_Transferred(sender As Object, e As Telerik.Web.UI.RadListBoxTransferredEventArgs)
        Label1.Text += "Items with Text/Value transferred: "
        For i As Integer = 0 To e.Items.Count - 1
            Label1.Text += "[" + e.Items(i).Text + "/" + e.Items(i).Value + "]"
    End Sub

    The code snippet above gets the transferred items' Text and Value property values and updates a Label's Text with the data.
