I am trying to bound combobox to a collection. Collection is returning 3 cols. How do I a specify DatavalueField and Datatextfield to 2 of the columns returned in my collection?

When I write following code Combox is populated with text showing MfnBusinessData.Item for each item.

Thanks

Dim ItemCollection As Collection(Of MfnBusinessData.Item)
    Dim oms = New MfnDataAccess.LookupDal
    ItemCollection = oms.GetLookupItems("OFXQuestionText", "FULL", "ALPHA", "en")
    RadComboBox1.DataSource = ItemCollection
    RadComboBox1.DataBind()
    'RadComboBox1.DataValueField = ItemCollection.Id
    'RadComboBox1.DataTextField = "Text"
