[Solved] unable to see progress area

[Mark DeMichele]

Hi there,

I'm trying to integrate the progress area control into an existing web application, and I'm not able to see the Progress Area when uploading a file via the standard asp:FileUpload control

Curiously, a web site started from scratch with a test page works just fine. 

I've gone through the web.config files in both places. In particular, I've commented out all references to modules in the web.config of the existing application, including the Spring framework which I suspected might be causing a problem. In spite of doing so, the progress area still doesn't appear.

Although I'm not getting an error, I did check http://www.telerik.com/support/kb/aspnet-ajax/upload/906-ajax-callback-error.aspx and went through everything:

- Went to http://mysite/Telerik.RadUploadProgressHandler.ashx and got the line of javascript
- no blocking handler mappings present
- no configuration in either web.config concerning trusts, so I would assume that since the basic case worked, it's a non-issue
- check if file exists setting is off
- added the forms suthentication setting for the handler - since I can access the handler via a HTTP request I assume it's also not an issue
- no URL rewriting. The server is running IIS 6 on Windows 2003 and there are no unusual ISAPI filters installed on either site.

Am I missing anything?

Thanks,
Mark

Hi Mark DeMichele,

Do you test on your local host? Can you try with a really big file (e.g. 150 MB)?
Alternatively, you can browse your application from another computer on the network.
Ajax on the page?

Interesting.. I found the culprit. Somehow, the following line in web.config (under system.web) causes the issue to occur. I verified it both using the existing web application and the bare-bones site I created.

 

        <trace enabled="true" localOnly="false" mostRecent="false" pageOutput="false" requestLimit="10000" traceMode="SortByTime" writeToDiagnosticsTrace="false"/>

 

If the enabled attribute is changed so that it has a value of “false” or the line is removed, then the progress area appears just fine. I tried to increase the requestLimit to 20000000 just for kicks, and the progress area still didn’t appear. I also tried to mess around with the flags, setting all of them to true, but to no avail.

 

Does this sound familiar?

Hi Mark DeMichele,

Actually, the trace should be disabled as stated here (check point 6)

Ah, I had missed that earlier. Thanks!

In the same document, you mention a limitation that the control does not work with web farms. Perhaps you folks could offer an option to write to a shared temp file for web farms?
