Did you register the RadUploadProgressHandler in web.config?

RadUpload Ajax callback error. Source url returned error: 12029
Hello Larson,
There are many reasons for receiving the error message “Callback Error,” and this is generally the solution:
1. Check that the RadUploadHttpModule and the RadUploadProgressHandler registration is correct.
You can do this if you access directly the handler’s URL from the browser in the following way:
http://mysite/Telerik. RadUploadProgressHandler.ashx
where mysite is your site’s URL.
If everything is registered correctly, you should see the following line:
var rawProgressData = {InProgress:false,RadProgressContextCustomCounters:false};
2. Check for other conflicting modules and handlers in the Web.config and the order in which they are registered.
3. Check for URL Rewriter rules which may redirect the call to Telerik. RadUploadProgressHandler.ashx to somewhere else.
I hope that this helps you.
Regards.
