As someone coming into silverlight programming from the ASP.NET world (and many earlier worlds), I'm absolutely astounded as to how completely broken and not-ready for BETA the combobox in Silverlight is when trying to populate it from any data source.

I've literally spent days trying to get a combobox in a datagrid to populate the items from a RIA domaindatasource or any other method of getting data from my entity framework (using domaindatasource) objects.

I've read so many contradictory/fragmented/error filled/incomplete blogs and other articles on the web that I could just hurl.

I've yet to get it to populate (then I have to tackle setting selected item which appears more broken).

This is supposed to be silverlight 4. IMHO it hasn't reached an alpha release for a 1.0 version yet.

If anyone has a clear cut, COMPLETE and ACCURATE example of doing this I'd love to see it.
