I am collecting data of a store through JSON Reader. Data received from server is in following format:

({"rights": "No Rights", "total":"2","results":[{"id":"10","c_code":"US","country":"United States"},{"id":"11","c_code":"UK","country":"United Kingdom"}]})
I have a button in Top Toolbar of a grid. When I click on this button, I want to display 'rights' value in alert message box. How it would be possible.

Can someone help me in this regards

Thanks in advance
