Query #2: If I try to disable the item (customized or not) in ngOnInit() it shows me this error:
From the query we suspect that you are trying to set a grid property in ngOnInit which is prior to the grid component render. So we suggest to change the grid properties on the created or load event, since component will be rendered at that point of time. Please refer to the below documentations for your reference,
Please get back to us for further assistance.
