    Hi all. I've been using Silverlight Upload for years (Q3/2013), and it works flawlessly. Now there are many browsers preventing SL from being used, so I've built an AJAX ASP.NET (Q3/2013) site to do the trick. It works fine on my development machine (Win 8.1/VS2012SP1/IIS7), but once deployed on our server (Win Srv 8, FW 4.5) the selected filed 2B uploaded remain in a red state. Using Firefox for developers, I've seen an error 404 trying to load WebResources.axd; so I've followed Telerik's suggestion found in this forum to troubleshoot the error, amended config.web file inserting reference to ScriptResource.axd, with no success. Is there anyone who can help me to get rid of this error? TIA

    Hi Saverio,

    Please go through the troubleshooting section for RadAsyncUpload in the documentation: https://docs.telerik.com/devtools/aspnet-ajax/controls/asyncupload/troubleshooting/common-issues#common-issues.

    Make sure that the Telerik.Web.UI.WebResource.axd is registered in the web.config and excluded from Windows Authentication. 
    If set remove the "runtimeVersionv2.0" attribute from preCondition for Telerik.Web.UI.WebResource.axd

    The following article will answer your questions in case you cannot register our handlers at the root of the application: https://www.telerik.com/support/kb/aspnet-ajax/details/register-telerik-http-handlers-in-nested-web-config.

     

    Best regards,

    Rumen
