RadUpload Progress Bar not updating

[Paul]

I have an ASP.NET user control "Upload.ascx" that contains a RadUpload control that I am using on a page in Sitefinity. Whenever I select a file to upload and submit the form, the ProgressArea appears, but the progress bar does not update, and the remaining time is a really huge number. Then the page posts back, resulting the the progress of the upload never being shown (it stays at 0%, even for large files). I searched around and found some similar issues online, but none of the solutions fixed my problem. I tried switching to a RadAsyncUpload control and changing my web.config runAllManagedModulesForAllRequests value to "true", but neither worked. I also tried a Telerik sample project with a RadUpload control that I found in another support thread, but that also displayed the same issue (but it works on the example page in the Telerik documentation). Might this be an issue with my DLL? I am using Telerik.Web.UI v2012.1.215.40 (Runtime v4.0.30319).

Thanks in advance for any assistance you can offer!

Hi Paul,

I have tested the provided code in a sample webforms project and everything is working fine. Could you please clarify that your URL is not structured like in the following help article(limitations number 4). Our recommendation is to us RadAsyncUpload control instead of the RadUpload. It has more features e.g. client side validation and there is no need to make a postback to validate the file. Also the control works out of the box with the RadProgressArea and there is no need for the RadProgressManager.
