How to tell DataSource that the data was changed outside?

[Brett]

I have a local data source which is a JS array. I setup transport methods to read/write the data. When the data is modified by Kendo widget like grid it works fine.

If I modify the array directly outside a widget in JS, how can I tell Kendo that the data source changed?

 

Thanks!

Hello, Brett,

There are different approaches depending on the scenario.

If a single item is added or deleted, the add and remove method can be used:

https://docs.telerik.com/kendo-ui/api/javascript/data/datasource/methods/remove

The other option is directly passing the changed data using the data method:

I hope this is helpful.
