I have a grid with a custom toolbar button to do a "global" update to the grid items. The Action is a normal MVC controller that returns a JsonResult. The action works correctly, but I'm not sure how to correctly handle the response - IE is asking if I want to download or open the JSON response. What I need to do is check the response for success, and refresh the grid or display an error message. How can I wire this up? Apologies if there's an answer already - I've searched, but can't seem to find anything.

Hello,

As far as I understand the requirement here is to use the custom button in the toolbar in order to make changes to one or more data items and sync its changes with the server. If so you can take advantage of the Kendo UI Grid API and Kendo UI DataSource API. 

A sample workflow for such scenario would be: 
  - access the dataSource property of the Kendo UI Grid to have a reference to the Kendo UI DataSource instance. 
  - the items in the DataSource can be accessed using the data method of the Kendo UI DataSource. 
  - once you have access to specific data item from the DataSource you can use set method to change the value for specific property.
  - when you are done with modifying items the sync method of the DataSource will make a call to the transport.update.url with updated items. 

If your scenario is different please provide more information in order to help you with your case.

Boyan,

    Thanks for the direction - I was thinking in terms of the Action() method, but the javascript route seems preferable.
