All my Telterik Control became disabled

[Christine]

Hi,

I am going through an issue with Telerik controls, all my Telterik Control because disabled, like RadEditor, RadListBox and RadAutoComplete. I installed the Telerik Version=2016.1.113.35, before that I was having the Telerik Version=2015.2.623.45. After installing I converted all my Application and its related components from .Net 3.5 to .Net 4.0, now all my Telerik Controls became disabled, the ones which were working before also became disabled.

Any help what could the reason and solution for it, any think like a link, a code snippet or even a suggestion would be helpful.

Here is my code:

Hi Christine,

I'm having a very similar issue...was this ever resolved?  Thanks!

Hello Tim,

The issue in the OP's case was an incorrect registration of our HTTP handlers (they had the "runtimeVersion 2.0" modifier). You can read more details here: http://docs.telerik.com/devtools/aspnet-ajax/general-information/troubleshooting/general-troubleshooting#using-the-telerik-controls-with-radscriptmanager-on-your-login-page-throws-an-error.

As I advised in your support ticket on this issue, the best  course of action is to copy them from the documentation: http://docs.telerik.com/devtools/aspnet-ajax/general-information/web-config-settings-overview#mandatory-additions-to-the-webconfig.
