JavaScript runtime error - Object doesn't support property or method 'telerik_ReportViewer'

Environment

Product Progress® Telerik® Reporting
Report Viewers HTML5-based Report Viewer

Description

The error message appears in the browser's console when running a web application with the HTML5 Report Viewer.

Error Message

0x800a01b6 - JavaScript runtime error: Object doesn't support property or method 'telerik\_ReportViewer'.  

Possible Cause

The HTML5 Report Viewer is an HTML\CSS\JS client-side widget. The viewer requires a link to jQuery v1.9.1. or above, which may be in contradiction with other components loading jQuery on their own.

Solution

Verify the page loads jQuery of version 1.9.1 or above only once.

Notes

If you use Telerik UI for ASP.NET AJAX RadScriptManager, it loads its embedded version of jQuery. You can use the external link to other jQuery file by setting the EnableEmbeddedjQuery property of RadScriptManager to false.
