RadAjaxNamespace is not found within the codebase

While testing the application on my development machine, I encountered an error message in the browser debug console stating "RadAjaxNamespace is not defined". Interestingly, this error does not appear when accessing the production server. Upon comparing the rendered html of both environments, I noticed that the web resource script include for RadAjax is missing on the dev machine experiencing the error. 

(Tag <script type="text/javascript" src="/WebResource.axd?d=...)

This issue started occurring after a recent reinstall of my machine. What could be causing the RadAjax control to fail in rendering the script include properly?

The application uses RadControls for ASP.NET AJAX version 2013.1.220.40 and RadAjax.Net2.dll version 1.5.1.0

Answer №1

It caught my attention that you have a mixture of old and new versions of Telerik controls in your project. Is there a particular reason for having the outdated controls included? If not, my recommendation would be to remove the older DLLs and stick with using only Telerik.Web.UI.DLL, Telerik.Web.UI.Skins.DLL, and Telerik.Web.UI.Design (if necessary for design-time). From what I understand, the old controls (such as RadControls for ASP.NET Classic) are no longer supported and could potentially cause issues related to browser and .Net compatibility. Additionally, integrating these outdated controls with newer ones may pose challenges and uncertainties.
