I managed to get batch editing working for the SharePoint 2010 list odata/rest service with the kendo ui datasource using the Microsoft datajs library (http://datajs.codeplex.com/
). It would be good though if I could combine the create, update and destroy operations in the same batch as well. It would be even better if I could combine the create, update and destroy operations of multiple datasources in the same batch. That would allow me to insert a new Order and its Order_Details in a single batch / unit of work / transaction.
