Data grid - Events

You can subscribe to the events emitted by the data grid to trigger custom behavior.

Subscribing to events

You can subscribe to one of the events emitted by providing an event handler to the grid.

The handler is a method that will be called with three arguments:

1. the parameters containing the information related to the event
2. the MuiEvent containing the DOM event or the React synthetic event, when available
3. the GridCallbackDetails containing the GridApi, only if DataGridPro or DataGridPremium is being used

For example, here is an event handler for the rowClick event:

const handleEvent: GridEventListener<'rowClick'> = (
  params, // GridRowParams
  event, // MuiEvent<React.MouseEvent<HTMLElement>>
  details, // GridCallbackDetails
) => {
  setMessage(`Movie "${params.row.title}" clicked`);
};

You can provide this event handler to the grid in several ways:

With the prop of the event

<DataGrid onRowClick={handleEvent} {...other} />

The following demo shows how to subscribe to the rowClick event using the onRowClick prop—try it out by clicking on any row:

With useGridApiEventHandler

useGridApiEventHandler('rowClick', handleEvent);

The following demo shows how to subscribe to the rowClick event using useGridApiEventHandler—try it out by clicking on any row:

With apiRef.current.subscribeEvent

apiRef.current.subscribeEvent('rowClick', handleEvent);

The following demo shows how to subscribe to the rowClick event using apiRef.current.subscribeEvent—try it out by clicking on any row:

Disabling the default behavior

Depending on the use case, it might be necessary to disable the default action taken by an event. The MuiEvent passed to the event handler has a defaultMuiPrevented property to control when the default behavior can be executed or not. Set it to true to block the default handling of an event and implement your own.

<DataGrid
  onCellClick={(params: GridCellParams, event: MuiEvent<React.MouseEvent>) => {
    event.defaultMuiPrevented = true;
  }}
/>

Usually, double clicking a cell will put it into edit mode. The following example changes this behavior by also requiring Ctrl to be pressed.
