I would like to has the followings for my form,



Order Header (Parent )

|- Order Item (Child)

|- Order Item BOM (GrandChild)



where order item and order item bom are show in grids. When user navigate the Order Item grid, the BOM grid will refresh to show only the BOM belong to the current Order Item row record. This can be achieve by hierachical grid but DevExpress do not provide this feature. How I can solve it ? Or use Infragistic that provide this feature is better ? Is SF support hierachical grid ?
