If the enablePersistence property is set to true, the grid property value is saved in the window.localStorage for reference.
You can get/set the localStorage value by using the getItem/setItem method in the window.localStorage.
/** get the Grid model
* "gridGrid" is component name + component id
*/
const value: string = window.localStorage.getItem('gridGrid');
const model: object = JSON.parse(value); /** set the Grid model
* "gridGrid" is component name + component id
*/
window.localStorage.setItem('gridGrid', JSON.stringify(model));
