[Solved] RadGrid - Batch Edit Mode with Model Binding

[John]

I am trying to implement model binding on RadGrid using SelectMethod, UpdateMethod, DeleteMethod and InsertMethod. (I have done this successfully in standard edit mode.) However, having problems when EditMode="Batch". Grid displays as expected, retrieving data through SelectMethod. However, when I try to save changes to modified rows, neither the UpdateMethod or DeleteMethod are called.

I have not been able to find a data model binding example that implements Batch Edit.

Here is my code. Is this supported? And if so, what am I missing? Thanks.
