There is no data source component that will work directly with the created service client.
You can use the OData Client T4 template
to generate the code, and then you need to consume the service. Finally you can use an ObjectDataSource component to wrap the data retrieval method, in which the service is consumed. This scenario is illustrated in the blog post I previously sent you.
If you need further help, please open a support ticket and send us a demo project that illustrates your settings and the problem.
