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);

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.
