Web API Service
The PivotGrid can communicate with a Web API service. The quantity of aggregated data is irrelevant when aggregation is performed on the server. For example, the widget works with a million aggregated records in this demo.
To configure access to a Web API service from the client, use the createStore method (part of the DevExtreme.AspNet.Data extension).
You should also set the remoteOperations option to true to notify the PivotGrid that data is aggregated on the server.
Thank you!
