Data grid - State

Initialize and read the state of the data grid.

Initialize the state

Some state keys can be initialized with the initialState prop. This prop has the same format as the returned value of apiRef.current.exportState().

Access the state

The state is exposed on the apiRef object. It is strongly advised not to access the state values directly because the state itself is not considered a public API and its structure can change.

The @mui/x-data-grid-pro package exposes a set of state selectors that take the apiRef.current.state as an argument and return a value. You can use them to get data from the state without worrying about its internal structure.

Direct selector access

The simplest way to use a selector is to call it as a function with apiRef as its first argument.

const pageSize = gridPageSizeSelector(apiRef);

With useGridSelector

If you want to access sole state value in the render of your components, you can use the useGridSelector hook.

const pageSize = useGridSelector(apiRef, gridPageSizeSelector);
Press Enter to start editing

Catalog of selectors

Some selectors are yet to be documented.

Save and restore the state

The current state of the grid can be exported using apiRef.current.exportState(). It can then be restored by either passing the returned value to the initialState prop or to the apiRef.current.restoreState() method.

Watch out for controlled models and their callbacks (onFilterModelChange if you use filterModel, for instance), as the grid will call those callbacks when restoring the state. But if the callback is not defined or if calling it does not update the prop value, then the restored value will not be applied.

Restore the state with initialState

You can pass the state returned by apiRef.current.exportState() to the initialState prop. In the demo below, clicking on Recreate the 2nd grid will re-mount the 2nd grid with the current state of the 1st grid.

Restore the state with apiRef

You can pass the state returned by apiRef.current.exportState() to the apiRef.current.restoreState method. In the demo below, clicking on Save current view will create a snapshot of the changes made in the state, considering the initial state. You can apply these changes on the grid later selecting a saved view in the Custom view menu.

Restore part of the state

It is possible to restore specific properties of the state using the apiRef.current.restoreState() method. For instance, to only restore the pinned columns:

apiRef.current.restoreState({
  pinnedColumns: ['brand'],
});
