HTML5 Report Viewer Styles Are Messed Up

Environment

Product Progress® Telerik® Reporting
Version Q2 2012 and later
Report Viewers HTML5-Based Web Viewers

Description

The HTML5 Report Viewer styles are messed or a JavaScript undefined error is thrown.

Cause

A possible cause about the occurrence of this issue is that relative paths may need adjustment.

Solution

You can see errors related to loading CSS and JavaScript files in the browser console. Inspect the rendered HTML to obtain more details if external CSS and JavaScript causes similar issues on the page and fix any relative paths that may need adjustment.

Generally, according to the Telerik Kendo UI JavaScript requirements, the page with the HTML5 Report Viewer must load jQuery v. 1.9.1 or later only once. In addition, the linked Telerik Kendo UI CSS and JS files have to be of the same version.
