RadGrid Edit question

This should be easy but I'm obviously missing something. I have a RadGrid on my web page. It loads correctly from my database. I also have an Edit icon on the RadGrid. I display an email address when clicked. This works as well. My email address displays and I can change the value and then update my database. My question is how to change the width of the email address? Not sure how to do this. It seems to be a textbox control but not certain. Any help would be appreciated. Thanks in advance!

Telerik Control Panel States "No Internet Connection"

I posted this here because I was unsure where this would go.

On a number of occasions recently (today being one of them), we will be running the control panel and the control panel will state "No Internet Connection". We work around this by just downloading the msi files, but that is much more time-consuming and full of making mistakes.

This can happen on one developer machine and not another (equal builds....equivalent firewall and antivirus....our dev machines are controlled by a network imaging process).

So, we're a bit at a loss. I and my other colleague have machines that are, for all intensive purposes, equal. We have done the normal things of disabling antivirus, disabling firewall, closing out all notable programs, etc. The thing is this doesn't happen on a consistent basis. It will happen on one deployment server and not another. Then, at another time, it will not happen on the previously affected server, and will happen on the previously unaffected server.

What we're looking for is some guidance as to how we can troubleshoot the problem.

Regards,
Doug

How to validate Sitefinity cryptographic weakness fix?

We are trying to contact Sitefinity to check status about the latest security vulnerability in Sitefinity due to cryptographic weakness [CVE-2017-9248]. As our version is older, we have to verify the steps we have taken is valid and is that enough for the security issue.

Our Sitefinity version is 3.7.2136

and what we did is, we prevented the access to Dialog Handler as suggested in http://www.telerik.com/support/kb/aspnet-ajax/details/cryptographic-weakness#prevent-access
by removing the handler in the web.config file and also changed Machine keys.

Can you please let us know if that will be enough for now? Is there a way to measure this and make sure that security is improved?

Slow Support.

We are a premium customer and expected at least 24hr responses, apparently that is not the case. Submitted a support ticket over 24hrs ago and still no response. Uggghh! Is this a trend?
