React Data GridSSRM Sorting

This section covers Server-Side Sorting using the Server-Side Row Model.

Sorting

Sorting is enabled by default in the grid and controlled via the sortable column definition attribute.

const [columnDefs, setColumnDefs] = useState([
    { field: 'country'},
    // Disable sorting by sport
    { field: 'sport', sortable: false },
]);

<AgGridReact columnDefs={columnDefs} />

For more details on sorting configurations see the section on Row Sorting.

Server-side Sorting

The actual sorting of rows is performed on the server when using the Server-Side Row Model. When a sort is applied in the grid a request is made for more rows via getRows(params) on the Server-Side Datasource.

The request object sent to the server contains sort metadata in the sortModel property, an example is shown below:

// Example request with sorting info
{
    sortModel: [
        { colId: 'country', sort: 'asc' },
        { colId: 'year', sort: 'desc' },
    ]
}

Notice in the snippet above that the sortModel contains an array of models for each column that has active sorts in the grid. The column ID and sort type can then be used by the server to perform the actual sorting.

The example below demonstrates sorting using the SSRM. Note the following:

The server uses the metadata contained in the sortModel to sort the rows.
Open the browser's dev console to view the sortModel supplied in the request to the datasource.
Try single / multi-column (using ⇧ Shift key) sorting by clicking on column headers.
