Is there a way to stop a kendo element from rerendering and triggering the databound event while i'm updating the data?
I'm looping through the data to update a field. but everytime a field is changed, the element rerenders and triggers the databound
 angular.forEach($scope.list.dataSource.data(), function (item) {});

Is it possible to only render and the databound be triggered only after the loop and not while looping?

Hi Louise,

Here you will find a simple implementation of a ListView with a DataSource configured, based on the described scenario. you will notice, that I have attached a handler for the dataBound event of the widget, which logs on the console each time the event is fired.

By clicking on the Button, the user overrides all the names of the displayed products. You will notice, that this, however, does not trigger the dataBound event. 

May I ask you to modify the attached so it reproduces the problem and send it back to us. This way we will be able to troubleshoot the issue locally and to provide you with the most appropriate assistance for your scenario.

I am looking forward to hearing from you.

Regards,
