Uncaught Error: Unexpected ajax response was received from the server.
This may be caused by one of the following reasons:

- Server.Transfer.
- Custom http handler.
- Incorrect loading of an "Ajaxified" user control.

Verify that you don't get a server-side exception or any other undesired behavior, by setting the EnableAJAX property to false.

Hi Tamilmani,

Version 2009.1.402.20 was created long before .NET Framework 4 and Visual Studio 2019 and it is not supported. It is also vulnerable and not quite compatible with modern browsers. We strongly advise upgrading to the latest versions for better security, stability, and support improvement.

Hi Vasko, Thanks for your help, we need to replace the Telerik.Web.UI dll (2009.1.402.20) into highlighted dll in our project references ? Main concern is it was working fine still last week in visual studio 2019 4.5 .Net Framework and Telerik.Web.UI 2009.1.402.20 dll, suddenly telRad related properties are not working.

Hello Tamilmani,

To address the issue with the Telerik.Web.UI 2009.1.402.20 DLL, here are some steps and considerations:

Confirm DLL Replacement

Upgrade to a Supported Version: Replacing the outdated Telerik.Web.UI 2009.1.402.20 DLL with a more recent version is indeed a correct approach. This will help ensure compatibility with Visual Studio 2019 and .NET Framework 4.5, as well as improve security and stability.

Troubleshooting Steps for Current Setup

Recent Changes: Since the issue arose suddenly, consider any recent changes in your environment. Check if there have been updates to Visual Studio, changes in project settings, or modifications in related code that might have affected the Telerik controls.
AJAX Configuration: Verify the AJAX settings in your application. Temporarily set the EnableAJAX property to false to determine if the issue is related to AJAX configuration.

For detailed upgrade instructions, refer to the following resources:

https://docs.telerik.com/devtools/aspnet-ajax/upgrade-compatibility/upgrading-instructions/upgrading-a-trial-to-a-developer-license-or-to-a-newer-version#manual-upgrade

Implementing these steps should help resolve the issue or at least provide a clearer path to identifying the root cause.
