JavaScript Data Grid: Components

You can create your own custom components to customise the behaviour of the grid. For example you can customise how cells are rendered, how values are edited and also create your own filters.

The full list of component types you can provide in AG Grid are as follows:

The remainder of this page gives information that is common across all the component types.

Registering Custom Components

There are two ways to tell the Grid to use a custom component:

  • Direct reference.
  • By name.

1. Direct Reference

The easiest approach is to refer to the Component class directly.

gridOptions = {

   columnDefs: [
       {
           field: 'country',
           cellRenderer: CountryCellRenderer,
           filter: CountryFilter
       },
   ],

   ...
}

The advantage of referencing Components directly is cleaner code, without the extra level of indirection added when referencing by name.

2. By Name

A Component is registered with the grid by providing it through the components grid property. The components grid property contains a map of Component Names to Component Classes. Components of all types (editors, renderers, filters etc) are all stored together and must have unique names.

gridOptions = {

   // register the components using 'components' grid property
   components: {
       // 'countryCellRenderer' is mapped to class CountryCellRenderer
       countryCellRenderer: CountryCellRenderer,
       // 'countryFilter' is mapped to class CountryFilter
       countryFilter: CountryFilter
   },

   // then refer to the component by name
   columnDefs: [
       {
           field: 'country',
           cellRenderer: 'countryCellRenderer',
           filter: 'countryFilter'
       },
   ],

   ...
}

The advantage of referencing components by name is definitions (eg Column Definitions) can be composed of simple types (ie JSON), which is useful should you wish to persist Column Definitions.

Providing Additional Parameters

Each Custom Component gets a set of parameters from the grid. For example, for Cell Renderer the grid provides, among other things, the value to be rendered. You can provide additional properties to the Custom Component (e.g. what currency symbol to use) by providing additional parameters specific to your application.

To provide additional parameters, use the property [prop-name]Params, e.g. cellRendererParams.

const gridOptions = {
    columnDefs: [
        { 
            field: 'price',
            cellRenderer: PriceCellRenderer,
            cellRendererParams: {
                currency: 'EUR'
            }
        },
    ],

    // other grid options ...
}

Grid Provided Components

The grid comes with pre-registered components that can be used. Each component provided by the grid starts with the namespaces 'ag' to minimise naming conflicts with user provided components. The full list of grid provided components are in the table below.

Date Inputs

agDateInput Default date input used by filters.

Column Headers

agColumnHeader Default column header.
agColumnHeaderGroup Default column group header.

Column Filters

agSetColumnFilter Set filter (default when using AG Grid Enterprise).
agTextColumnFilter Simple text filter (default when using AG Grid Community).
agNumberColumnFilter Number filter.
agDateColumnFilter Date filter.

Floating Filters

agSetColumnFloatingFilter Floating set filter.
agTextColumnFloatingFilter Floating text filter.
agNumberColumnFloatingFilter Floating number filter.
agDateColumnFloatingFilter Floating date filter.

Cell Renderers

agAnimateShowChangeCellRenderer Cell renderer that animates value changes.
agAnimateSlideCellRenderer Cell renderer that animates value changes.
agGroupCellRenderer Cell renderer for displaying group information.
agLoadingCellRenderer Cell renderer for loading row when using Enterprise row model.

Overlays

agLoadingOverlay Loading overlay.
agNoRowsOverlay No rows overlay.

Cell Editors

agTextCellEditor Text cell editor.
agSelectCellEditor Select cell editor.
agRichSelectCellEditor Rich select editor.
agLargeTextCellEditor Large text cell editor.

Master Detail

agDetailCellRenderer Detail panel for master / detail grid.

Overriding Grid Components

It is also possible to override components. Where the grid uses a default value, this means the override component will be used instead. The default components, where overriding makes sense, are as follows:

  • agDateInput: To change the default date selection across all filters.
  • agColumnHeader: To change the default column header across all columns.
  • agColumnGroupHeader: To change the default column group header across all columns.
  • agLoadingCellRenderer: To change the default loading cell renderer for Enterprise Row Model.
  • agLoadingOverlay: To change the default 'loading' overlay.
  • agNoRowsOverlay: To change the default loading 'no rows' overlay.
  • agCellEditor: To change the default cell editor.
  • agDetailCellRenderer: To change the default detail panel for master / detail grids.

To override the default component, register the custom component in the GridOptions components property under the above name.

const gridOptions = {
   // Here is where we specify the components to be used instead of the default
   components: {
       agDateInput: CustomDateComponent,
       agColumnHeader: CustomHeaderComponent
   }
};
