Hi experts,

I'd like to show hierarchical data in xamdatagrid. I've tried bind data source to xamdatagrid, but the look is not what I want. So I need your help point me to the right place. If xamDataGrid is not the right control, please let me know which one i should use.

My datasource is like following with 3 levels. I have an Grandfather observablecollection, and each Grandfather contains an father collection, and each father contains a child collection. 

Grandfather: name, age 
               |____father: name, age
                           |__________________child: name, age

And the result should be rendered like following

----------------------------------------------------------------------------------------------------------------------------------------------------
|grandfather1.name|father1.name|child1.name||child2.name||child3.name||child4.name||child5.name||child6.name||child7.name|
__________________________________________________________________________________________________________________________
                             |father2.name|child1.name||child2.name||child3.name||child4.name||child5.name||child6.name||child7.name|
___________________________________________________________________________________________________________________________
|grandfather2.name|father1.name|child1.name||child2.name||child3.name||child4.name||child5.name||child6.name||child7.name|
__________________________________________________________________________________________________________________________
                            |father2.name|child1.name||child2.name||child3.name||child4.name||child5.name||child6.name||child7.name|

Please help!!!
Thanks.
