Hi experts,

I've posted another question in the same queue, but the format is terrible, please ignore it.
I'd like to show hierarchical data in xamdatagrid. The UI should like the picture in this link.  If xamDataGrid is not the right control, please let me know which one i should use.

My datasource is like following with 3 levels. A list of Country, and each Country contains a list of State, and each state contains a list of City.

Country: name,
               |____State: name
                           |__________________City: city, person, age, occupation

Please help, Thank you in advance.
