如何将一个AspxListBox绑定到两个以上的属性

Question

Maybe the title isn't clear enough.

I have a data set whose objects have a key, a text and description. how do i bind this description property to the list box so that i can manipulate in client-side? I cannot show the description to the user and its not something i can derive from the key and text.

--EDIT-- apparently i cannot submit the question as-is, i need to show what i have done so far:

//lbTemplates_OnCallback
            var elementIds = new[] { SmsElementKey };// ConfiguredElements.Split(',').Select(long.Parse).ToArray();
            var v = smsTemplateDao.ListByElementTypes(elementIds);
            lbTemplates.DataSource = v;
            lbTemplates.DataBind();
            lbTemplates.SelectedIndex = -1;

The markup:

<dx:ASPxListBox ID="lbTemplates" runat="server" ClientInstanceName="lbTemplates" EnableViewState="False" Height="210px" OnCallback="lbTemplates_OnCallback" Width="220px"  ValueField="ParkElementId" TextField="ElementPath">
<ClientSideEvents SelectedIndexChanged="UpdateButtons" Init="UpdateButtons" />
</dx:ASPxListBox>

您可以同时使用DataTextField和DataValueField。
