I finally found the solution(thanks to you), but having trouble to get it to work in my app. I have few more bells and whistles, can you give a hand if you have time Thanks

  Sure, just tell me where do you have issues. I would try to resolve it. :)

  Why here (Expander Header = "{Binding Name}") is used to bind Name, and not to the Country? Why, if you specify a binding to Country, a group name is not visible? Group is going around the country, rather than by name.

Good example and well explained, thanks. One question though, how would you go about setting the FontWeight of the group header? Chris.

  That did the job, thanks for the help!

  perhaps the following should work. <Expander Header="{Binding Name}" IsExpanded="True"> <Expander.Header> <TextBlock Text={Binding Name} FontWeight="Bold"/> </Expander.Header> <ItemsPresenter /> </Expander> Thanks Diptimaya Patra

  You got to remove the Header from the begining, I forgot that. :)
