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, which is part of the DevExtreme.AspNet.Data extension. This extension also allows you to configure server-side data processing for DevExtreme widgets.
You should also set the remoteOperations option to true to notify the PivotGrid that data is aggregated on the server.
Feel free to share demo-related thoughts here.
If you have technical questions, please create a support ticket in the DevExpress Support Center.
