Hello,

As far as I understand from the provided information you need to refresh the data of a Grid bound to a local data source, but the refresh method does not take effect. 

Even though the Grid is bound to a local dataSource the refresh method should render the new items. This is demonstrated in the Dojo linked here.

You could also try to use the setDataSource method if it is suitable for in your scenario:

- https://docs.telerik.com/kendo-ui/api/javascript/ui/grid/methods/setdatasource

Changing the items using the setDataSource method is demonstrated in the Dojo example linked here.

I will appreciate it if you could provide more details about the exact implementation on your side, so we could understand the scenario better. It will be very helpful if you could prepare and send us a Dojo example where the behavior is demonstrated, so we could provide appropriate assistance. If it is more easier for you you could modify the Dojo examples linked above.

Until we clarify the exact scenario I will change the status of the item to 'Need more info'

Looking forward to your reply.

Regards,
