Hi,
Following an test upgrade to .Net 4.5.1 I have had a problem with reporting. Webpages that used to work now don't workl properly.

I have reduced the page down to a small sample. The problem is that when a filter button is pressed the ajax call is done with the reportviewer flashing a loading panel then it shows the "The source of the report definition has not been specified." message. Looking at the codebehind the report is generated OK and is in fact applied to the report viewer. As mentioned this all works fine with .Net 3.5.

To further test I disable Ajax on the AjaxManager and then following the post back the control works as it should so this is definitly an Ajax issue of some sort. I am posting the code below.

It is worth noting that I have tried this on two distinct website solutions that I have and exactly the same issue appears.

Many thanks for any help.

Regards

Jon

Hi Jon,

The provided code illustrates a supported AJAX scenario (ASP.NET ReportViewer AJAX support), and the viewer will be updated successfully on uxLoginButtonClick.

The attached demo project illustrates our test. It uses Telerik Reporting Q2 2014 and Telerik UI for ASP.NET AJAX Q2 2014 (.NET 4).

In order to troubleshoot the issue further, please use your support ticket #872155 on the same question and send us a demo project with all settings, that reproduce the problem.
