Below, is an error I get now randomly on different pages that have telerik controls, I never seen these error before, until I upgaded to version 2012.2 912

Error Message: The given key was not present in the dictionary.
Stack Trace:

Hello,

From the CallStack it looks like the serialized data (that keeps client state of Radinput) send  to the server is not correct. But I can not be sure why you are facing this issue without able to replicate it here. Is there something common belong the pages in which you get the error? Did you inherited the controls and/or did you override some client side methods of the controls?

All the best,

All I did was upgrade from the previous version to the new version.

I can't reproduce the errors on my own, but when it's running live and people use the website these errors become very abundant in the error logs, before the upgrade they were non-existant.  I made ZERO code changes, just performed the upgrade because of the fix it has to allow you to put quotes into the radgrid again.

The only thing in common is these screens use the Rad Tab Strip Control, the Rad Grid Controls, and the Rad Window Control and they all share the same master page. 

I was hoping the new version fixed the issue below, but it did not.  (I'm always terrified of upgrading for fear it will make things worse). (A lot of people around the web says telerik is the cause of it.)  Which I also can't reproduce on my own, but is also abundant in the error logs.

Error Message: Invalid length for a Base-64 char array.

Hi,

Do you have login page in this sites that browsers can use auto-complete to fill username/passwords?
If the browser has stored some of the hidden fields and now it send them, and we expect different format, and parsing error will happen.
If some of your sites is public, can you share a link with us?

The pages are not under login, that causes the issue.. 

This particular site is public, these are the two pages that the error shows up the most. 

http://www.unlocktheinbox.com/blacklist/bl/telerik.com/ 
and 
http://www.unlocktheinbox.com/dnslookup/mx/telerik.com/ 

I can't reproduce it on my own, but I'm wondering it some how a search engine crawl is causing it to happen.

Hi,

We examined your site, and didn't found any reason for this strange behaviour. I am not sure if the crawlers can submit some invalid data thought the client state input. We will investigate the issue further, to make the InputControl stable on submitting invalid data.

hi, i experience the same problem, is there any solution for this?

Hi Tini,

As this thread is rather old I would ask you to open a separate forum thread and share the exact issue you are facing. Also providing the information for your page configuration and the version of the controls you are using will help us better understand your case and provide proper solution.
