 First, set `rowsLoadingMode="server"`.
 Then, set `rowCount` to reflect the number of available rows on the server.
 Third, set a callback function on `onFetchRows` to load the data corresponding to the row indices passed within `GridFetchRowsParams`.

 :::info
 In order for filtering and sorting to work you need to set their modes to `server`.
 You can find out more information about how to do that on the [server-side filter page](/x/react-data-grid/filtering/#server-side-filter) and on the [server-side sorting page](/x/react-data-grid/sorting/#server-side-sorting).
