React Data GridQuick Start

This page covers the key concepts of AG Grid: A high performance, feature rich, React Table and React Data Grid.

Your First React Data Grid

Add AG Grid to your application in these steps:

1. NPM Install

Install the ag-grid-react package, which also installs ag-grid-community:

npm install ag-grid-react

2. Import the React Data Grid

import { AgGridReact } from 'ag-grid-react'; // React Data Grid Component

3. Register Modules

Register the AllCommunityModule to access all Community features:

import { AllCommunityModule, ModuleRegistry } from 'ag-grid-community'; 

// Register all Community features
ModuleRegistry.registerModules([AllCommunityModule]);

4. Define Rows and Columns

const GridExample = () => {
    // Row Data: The data to be displayed.
    const [rowData, setRowData] = useState([
        { make: "Tesla", model: "Model Y", price: 64950, electric: true },
        { make: "Ford", model: "F-Series", price: 33850, electric: false },
        { make: "Toyota", model: "Corolla", price: 29600, electric: false },
    ]);

    // Column Definitions: Defines the columns to be displayed.
    const [colDefs, setColDefs] = useState([
        { field: "make" },
        { field: "model" },
        { field: "price" },
        { field: "electric" }
    ]);

    // ...
}

5. React Data Grid Component

The AgGridReact component is wrapped in a parent container div. Style is applied to the parent container. Rows and Columns are set as AgGridReact component attributes.

return (
    <div
        // define a height because the Data Grid will fill the size of the parent container
        style={{ height: 500 }}
    >
        <AgGridReact
                rowData={rowData}
                columnDefs={colDefs}
        />
    </div>
)

6. Running the React Data Grid

Below is a live example of the application running. Click </> Code to see the code.

Now that you have a basic React Data Grid running, the remainder of this page explores some of the key concepts.

Showing Data

Mapping Values

The field or valueGetter attributes Map Data to Columns. A field maps to a field in the data. A Value Getter is a function callback that returns the cell value.

The headerName provides the title for the header. If missing the title is derived from field.

const [columnDefs, setColumnDefs] = useState([
    { headerName: "Make & Model", valueGetter: p => p.make + ' ' + p.model},
    { field: "price" },
]);

<AgGridReact columnDefs={columnDefs} />

Text Formatting

Format text for cell content using a Value Formatter.

const [columnDefs, setColumnDefs] = useState([
    { field: "price", valueFormatter: p => '£' + p.value.toLocaleString() },
]);

<AgGridReact columnDefs={columnDefs} />

Cell Components

Add buttons, checkboxes or images to cells with a Cell Component.

const CustomButtonComponent = (props) => {
    return <button onClick={() => window.alert('clicked') }>Push Me!</button>;
};

const [colDefs, setColDefs] = useState([
    { field: "button", cellRenderer: CustomButtonComponent },
    // ...
]);

Resizing Columns

Columns are Resized by dragging the Column Header edges. Additionally assign flex values to allow columns to flex to the grid width.

const [columnDefs, setColumnDefs] = useState([
    { field: "make", flex: 2 }, //This column will be twice as wide as the others
    { field: "model", flex: 1 },
    { field: "price", flex: 1 },
    { field: "electric", flex: 1 }
]);

<AgGridReact columnDefs={columnDefs} />

Example

This example demonstrates mapping and formatting values, cell components, and resizing columns.

Working with Data

By default, the row data is used to infer the Cell Data Type. The cell data type allows grid features, such as filtering and editing, to work without additional configuration.

Filtering

Column Filters are embedded into each column menu. These are enabled using the filter attribute. The filter type is inferred from the cell data type.

const [columnDefs, setColumnDefs] = useState([
    { field: "make", filter: true },
]);

<AgGridReact columnDefs={columnDefs} />

There are 5 Provided Filters which can be set through this attribute. You can also create your own Custom Filter.

Floating Filters embed the Column Filter into the header for ease of access.

const [columnDefs, setColumnDefs] = useState([
    { field: "make", filter: true, floatingFilter: true },
]);

<AgGridReact columnDefs={columnDefs} />

Editing

Enable Editing by setting the editable attribute to true. The cell editor is inferred from the cell data type.

const [columnDefs, setColumnDefs] = useState([
    { field: "make", editable: true },
]);

<AgGridReact columnDefs={columnDefs} />

Set the cell editor type using the cellEditor attribute. There are 7 Provided Cell Editors which can be set through this attribute. You can also create your own Custom Editors.

const [columnDefs, setColumnDefs] = useState([
    {
        field: "make",
        editable: true,
        cellEditor: 'agSelectCellEditor',
        cellEditorParams: {
            values: ['Tesla', 'Ford', 'Toyota'],
        },
    },
]);

<AgGridReact columnDefs={columnDefs} />

Sorting

Data is Sorted by clicking the column headers. Sorting is enabled by default.

Row Selection

Row Selection is enabled using the rowSelection attribute.

// Column Definitions: Defines the columns to be displayed.
const [columnDefs, setColumnDefs] = useState([
    { field: "make" },
]);
const rowSelection = useMemo(() => { 
	return {
        mode: 'multiRow',
    };
}, []);

<AgGridReact
    columnDefs={columnDefs}
    rowSelection={rowSelection}
/>

Pagination

Enable Pagination by setting pagination to be true.

const pagination = true;
const paginationPageSize = 500;
const paginationPageSizeSelector = [200, 500, 1000];

<AgGridReact
    pagination={pagination}
    paginationPageSize={paginationPageSize}
    paginationPageSizeSelector={paginationPageSizeSelector}
/>

Example

This example demonstrates filtering, editing, sorting, row selection, and pagination.

Themes & Style

Themes

Grid Themes define how the grid looks (colors, font, spacing etc). The default theme is called Quartz. You can choose a different theme, or customise a built-in theme by changing parameters. Here we create a new theme based on Quartz:

import { themeQuartz } from "ag-grid-community"; // or themeBalham, themeAlpine

const myTheme = themeQuartz.withParams({
    /* Low spacing = very compact */
    spacing: 2,
    /* Changes the color of the grid text */
    foregroundColor: 'rgb(14, 68, 145)',
    /* Changes the color of the grid background */
    backgroundColor: 'rgb(241, 247, 255)',
    /* Changes the header color of the top row */
    headerBackgroundColor: 'rgb(228, 237, 250)',
    /* Changes the hover color of the row*/
    rowHoverColor: 'rgb(216, 226, 255)',
});

...
return (
    <div>
        <AgGridReact theme={myTheme} rowData={...} columnDefs={...} />
    </div>
)

Figma

If you are designing within Figma, you can use the AG Grid Design System to replicate the Quartz and Alpine AG Grid themes within Figma. These default themes can be extended with Figma variables to match any existing visual design or create entirely new AG Grid themes. These can then be exported and generated into new AG Grid themes.

Cell Style

Define rules to apply Styling to Cells using cellClassRules. This can be used, for example, to set cell background colour based on its value.

.rag-green {
    background-color: #33cc3344;
}

const [columnDefs, setColumnDefs] = useState([{
    field: 'electric',
    cellClassRules: {
        // apply green to electric cars
        'rag-green': params => params.value === true,
    }
}]);

<AgGridReact columnDefs={columnDefs} />

Row Style

Define rules to apply Styling to Rows using rowClassRules. This allows changing style (e.g. row colour) based on row values.

.rag-red {
    background-color: #cc222244;
}

const rowClassRules = {
    // apply red to Ford cars
    'rag-red': params => params.data.make === 'Ford',
};

<AgGridReact rowClassRules={rowClassRules} />

Example

This example demonstrates cell style and row style.
