Using detect changes() in a component will immediately run change detection in that component and its children. This method is helpful when we refresh the gird after performing any operation on it. It will automatically refresh the grid without refreshing the page.

First import ChangeDetectorRef to component where we want to use it.

import { ChangeDetectorRef } from ‘@angular/core’;

Now inject it.

constuctor(private changeDetactor : ChangeDetectorRef )

{

}

After that use it in method where you perform manipulation operations. Use detectChanges method to do this.

this.changeDetactor.detectChanges()
