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.
