Hi, can you explain what is the difference between igEditors:XamComboEditor and ig:XamComboEditor?

Specifically I need to use a simple XamComboEditor in a WPF form (using Infragistics NetAdvantage 2011.2) that displays a few items manually added (such as Male and Female) but I need to style the template so that each item is colored differently (say blue and pink) or each has a picture and to specify margins.

Thank you
