Please check R3 2016 release notes and the list of changes.
Check the HTML rendered on the page and if HTML elements of TelerikReporting viewers are there. Also check the browser's Console for errors. Debug the code to trace if the button click event is handled correctly.
In order to troubleshoot the problem further, please post details about errors, or open a support ticket and send us the upgraded project in a ZIP file (you can exclude Telerik DLLs to reduce the size of the ZIP).

Please test the following settings:
- Host the application in Local IIS via Visual Studio (project - Properties - Web tab) or disable BrowserLink in Visual Studio before running the application.
- Verify that the page with the viewer loads only one version of jQuery.
If you need further help, please open a support ticket and send us a demo project that illustrates the settings and reproduces the problem.

If you are using the old ASP.NET WebForms ReportViewer, check AJAX Support.
If you are using the HTML5 Viewer or its WebForms wrapper, the wrapper renders a Javascript object in the page and registers scripts on the page. Also the viewer uses AJAX requests to connect to an instance of the Reporting REST service. Thus using the HTML5 viewer in an AJAX panel is not needed, it is not making postbacks.
