The scenario I'm trying to achieve is to have a hierarchy grid. The first grid will be an array of objectA and the nested grid will be an array of objectB. I will fetch the first array of objectA via ajax and use that array as the datasource.
That all seems simple enough, the tricky part is that I want to fetch objectB the same way as objectA but only if/when the user expands one of the objectA items. A and B have a one to many relationship, like a folder to a file. I want to use the ID of A to pull all the B's associated with A when the user expands the grid.
It's not realistic to simply grab every single B and figure it out later. There could be millions of records for both A and B. I'm only going to be displaying 250 A's per page but need every single B related to A to show up when A is expanded.
Hopefully that made sense... In short, I need to know if I can dynamically fetch and insert a datasource when the user expands an item.
Thanks
