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.
