Error with Gantt in Chrome with 'ejicons.woff?-dzszjm'


I'm implementing Gantt control in my project in Visual Studio 2010 and .Net 4.0
I try to deploy the gantt application to my local server IIS v5.1.

The Gantt run correctly in Firefox browser, but in Chrome the web is freeze.
When we open the Chrome developer tool, we observed the web is freeze when it request "/Content/ej/common-images/ejicons.woff?-dzszjm"  (attached image):

In Firefox browser, the Firebug don't show a request to this file ("ejicons.woff?-dzszjm").

We use the following reference to scripts and CSS:

<%@ Register Assembly="Syncfusion.EJ.Web, Version=12.4400.0.24, Culture=neutral, PublicKeyToken=3d67ed1f87d44c89"

We try to fix this problem adding the following MIME type declarations "application/x-font-woff" via IIS Manager without result :(
 (ref. Why is @font-face throwing a 404 error on woff files? )

Hi OneTx,

Thanks for using Syncfusion product.

We have analyzed on this issue you have reported. We suggest you to do the following options to overcome this,

  1. We have to add the below code in web.config file in Visual studio.



<remove fileExtension=".woff" />

<mimeMap fileExtension=".woff" mimeType="application/font-woff" />



2.Or else we can change in IISExpress definition,

a. It is in ~\Documents\IISExpress\config\applicationhost.config

b. Search for .woff and you can find the below line.

<mimeMap fileExtension=".woff" mimeType="font/x-woff" />

c. Change its mimeType to “application/font-woff”

<mimeMap fileExtension=".woff" mimeType="application/font-woff" />

d. Again restart your application.

We have prepared a sample based on this and you can find the sample under the following location:
