RADUpload POST locking up

[Scott Manning]

I have a simple form that has the RADUpload and RADProgressbar on it.  I have a save and cancel buttons (ASP:BUTTONS) and have registered thr respective Telerik controls in the web.config file (See Below) and when I press the Save (Submit) button, the page never returns.  Eventually I will get an ajax time out error.  The project is .NET 4.0 and I am using the Telerik controls v4.0.30319.  Note, when I also press the cancel button, I still have a locked up page.  I have tried many different combinations such as
* uploaded zero files
* 1 very small file and
* 1 very large file

Hello Scott Manning,

I am not sure that the problem is related to RadUpload/RadProgressArea. Does the issue reproduce when you comment out them? What happens if you try to upload a file using the standard ASP.NET FileUpload? I suggest hat you do a http monitoring using a tool like fiddler. It should show what is going wrong with the request. Please take a look at the following help article for information on how to do that.

I used wireshark so it would not interfere with the traffic. When I press the save button, I see the GET /Telerik.RadUploaderProgressHandler.ashx?RadUrid=1d63…

 

I never see a response back from the handler.  I can remove the radupload and radprogress components from the web page and the page moves to the next page when the user presses the save button.  It is only when I add these two controls that seem to lock up the page when the Save button is pressed.

Hi Scott Manning,

The interesting thing here is that you receive Ajax timeout error. Now, RadUpload cannot upload files using AJAX calls. This is a limitation of the XmlHttpRequest component, used in all AJAX frameworks for asynchronous calls to the application. In order to upload a file your application must perform a full page postback. Have you applied the workarounds to disable ajax when upload as listed here?

Also, I think that the fiddler log is going to be more helpful because it will show all requests generated from the page. The packett that you have captured with WireShark is targeting the RadUploadProgressHandler, which is responsible for the progress monitoring, not the very upload. Could you please send us FiddlerCap log?
