I tried to bind custom data to XamDatagrid.
My custom data class is follows.

I want to bind AccessAreaDataByGroup collections to XamDataGrid.
The AccessAreaDataByGroup has AccessAreaDataByRcu collection, and the AccessAreaDataByRcu has AccessAreaDataByDoor collection.

My problem is I don't want Heirarchical bind AccessAreaDataByRcu collection and AccessAreaDataByDoor collection.
I want to bind like belows.


                                  Rcu1           Rcu2            Rcu3             Rcu4             Rcu5
Group      Name    door1  door2  doo1  door2  door1  door2   door1  door2   door1  door2
  1            test1      true   false    true  false     true   false      true   false      true   false
  2            test2      true   false    true  false     true   false      true   false      true   false
  3            test3      true   false    true  false     true   false      true   false      true   false
  4            test4      true   false    true  false     true   false      true   false      true   false
  5            test5      true   false    true  false     true   false      true   false      true   false
  6            test6      true   false    true  false     true   false      true   false      true   false
  7            test7      true   false    true  false     true   false      true   false      true   false
