We have a bunch of reports and report viewer in our application that were working just fine.  We were using buttons to make the reports visible.  We just upgraded to the latest version of Telerik reporting and now none of the reports will open up when the buttons are clicked.  We also upgraded our UI for ASP.net AJAX to the latest version as well.  Not sure if that would effect it also.

Hi Troy,

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).

Stef

Hi Troy,

Please test the following settings:
  1. Host the application in Local IIS via Visual Studio (project - Properties - Web tab) or disable BrowserLink in Visual Studio before running the application.
  2. 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.

Stef

It seems like there is an issue when the report viewer is inside an AJAX panel.  All our report viewers have been inside panels without a problem until we got the latest update.

Hello Troy,

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.

Stef

Thanks for your help.  It was the browserlink being enabled that was causing it.  We recently upgraded visual studio for 2012 to 2015.
