Why use object data source in asp.net 2.0

[b_rahul]

I have been using object data source in asp.net 2.0 for a couple of months now and this way of binding data for simple applications is reaaly cool but as things get a little comlicated like 1.Binding a form view to a Grid view's selection with composit primary keys 2.Binding to a checked list box where checked status is data driven people start pointing that it is similar to .net 1.1. Could some one pls point me to How to use the Object data source for binding data in the above scenarios. Thanks & Regards Rahul
