React Data Grid - Remote Grouping

Remote (server-side) operations can boost the DataGrid's performance on large datasets. In this demo, the DataGrid works with a million records seamlessly because they are processed on the server.

To notify the DataGrid that it works with a pre-processed dataset, set the remoteOperations property to true.

To give you the ability to edit code on the fly, the demo uses SystemJS. For this reason, launching the demo takes some time. We strongly recommend that you do not use this approach in real projects.
Backend API

You can also specify properties that allow the DataGrid to load data on demand to reduce the amount of transmitted data. Set the grouping.autoExpandAll property to false to collapse all the groups at startup. Data for each group is loaded only when the user expands the group. Enable the "virtual" scrolling.mode to load only those records that come into the viewport when the grid is scrolled vertically.

The DataGrid communicates with the server according to a protocol. Refer to the Server-Side Data Processing article for information on it.

NOTE

The data source in this demo is configured to return only 1000 records per request.
