Odd problem with edge

[Neil]

Hi,

   I am responsible for a web forms applications which has  been working fine for quite  a while. We've gotten to IE 11 and we've started having problems. So we changed to edge and found other problems. IE 11 was sending an enter key on a save of screen which caused problems with the applications. Once we changed to Edge we encountered even weirder problems:
1. We have a number of telerik dropdowns (radComboBox). There are a few that, if they are changed to the non default  values, shift back to the default value when save button is clicked. The weird thing is that this is only happening on two of the dropdowns, always the same two. The other drop downs that are working fine (which is most of them, as many as fifty). So these two that aren't working are "random". This is the second time we've found something like this. This is happening on two web forms
2. We switched to the same web form and used IE 11. The problem went away. 

In both cases where this happened this has happened with random dropdowns. However it always happens with the same two dropdown. Just to clarify, all the dropdowns, the ones that work and the one's that don't,  have exactly the same two values in them:
"GO"
"No GO".

Any help would be appreciated.

Thanks,
Neil Newton

Hi Neli,

To narrow down the issue I would suggest:

• Test the application with Chrome and also with the Edge Cromium browsers, to see if the issue appears there as well.
• Use the DevTools(F12) of the browser to check for eventual JavaScript errors on the page - Troubleshooting JavaScript errors.
• Check the Network tab for failing requests - Inspect Network Requests
• In case there is enabled AJAX on the page, disable it temporarily and test the application while monitoring for JavaScript errors again - Get more descriptive errors by disabling AJAX

If none of these is helping in troubleshooting, we would need some more details of the concrete scenario in order to help. Could you please share a screenshot or a video of the problematic behavior so that we can have a better understanding of the problem?

It would also be very helpful if you share an isolated version of the project replicating the problem, so we can run it and debug it locally, see Isolating a problem in a sample project.

Looking forward to hearing from you.

Kind regards,
Doncho
