We are using version 2011.3.1305.35

We have a radgrid which was in production for the past 10 years.

Last few days, we have been receiving errors when user tried to edit a row. This happens only in chrome and not on firefox. Even on chrome, it does not happen for everyone. For example , me and my colleague have the same version of Chrome browser. It happens regualrly on his browser. I do not get that error.

This issue started in the last 30 days.

Our Chrome version : 89.0.4389.90 

Any idea why we are having this issue and how we can fix this?

Thanks in Advance

Hi Jagat,

If the application works on one computer browser but fails on the other (regardless of the browser), the issue is rather related to the Environment. You may need to verify the environment (browser settings, cache, proxy, browser extension, etc..)

If the application works well in one type of browser (Firefox) but does not work in another (Chrome), then there might be a JavaScript problem that breaks in Chrome but does not in Firefox due to compatibility problems.

Visit the Troubleshooting section of our Documentations at General Troubleshooting and see if the issue is known and whether we have an answer for it.

You may also try debugging the application using the Browser's Developer Tools. For instructions/tips, check out the Debug JavaScript section of the Improve Your Debugging Skills with Chrome DevTools Blog post.

There might be a problem on the server and if AJAX is enabled, that could cause similar problems. I suggest disabling AJAX while Troubleshooting or Developing the application and only enable it once the App works as expected. See Get more descriptive errors by disabling AJAX.

For tips and tricks for debugging an application on the server-side, check out the 6 Server-Side Debugging Tips That Will Make Developing Easier Blog post.

My main advice is to upgrade the Telerik Components to the latest version. Since 2011 we have released many Bug fixes and New/Improved features that you can benefit from. 

Note that some issues can only be fixed by upgrading the Telerik Assemblies. Patches or fixes will not be provided for issues that have been fixed in a newer version, see Old Versions Support Policy in UI for ASP.NET AJAX
