Issue with Rad controls

[Vivek]

Hello

I have a Telerik installation on server. Earlier all controls were fine, but now all of a sudden none of them work.
I have copied the Telerik.Web.UI.dll file to the bin folder.

Any quick help will he appreciated.

Screenshot for reference

Controls visible in the image:
1. RadTree

Just an ideea: check the IIS web site (or project) properties. Is it using the right .net framework?

The website has been configured to run under. NET 4.0 (there has been no change to it when it was working).

I was thinking that it may be a mismatch between the Telerik DLL you are using (that comes in two versions, 35 and 40) and the site .net settings... If this is not the case you can also check for multiple DLL versions (one in Bin and another one in Assembly).

Hi Vivek,

Do you experience this problem only under Internet Explorer? If so, it is possible that you have reached the limit of CSS files that can be loaded by the browser. Please take a look at the following blog post for more information on the subject and a possible solution:
Internet Explorer CSS limits

If this is not the case, could you please provide more detailed information on the specific scenario?

• Which version of RadControls for ASP.NET AJAX is used in the application?
• Under which browser and its version the problem occurs?
• Could you please check if any of the requests to WebResource handlers do not return an error? If so, could you please try to enable CDN support for the skins and see if the problem still occurs?
• Could you please provide a simple fully runnable project and / or a live URL reproducing the problem so we can investigate it further?

Kind regards,

I can confirm the project has been built with .NET 4.0 and also the Telerik DLL i'm using is for 4.0.

I'm working on setting up the project for you. I would not want to disclose the URL and/or other details. Can I PM you instead ?

[Dobromir]

Yes Vivek, you can open formal support ticket where you can attach the project or provide the live URL. The tickets are not public but are visible only to the sender and Telerik Support Staff.

Adding an exception to the URL-Rewite module helped:

<rule name="WebResource" stopProcessing="true">
<match url="^.*WebResource.*$" />
<action type="None" />
