I'm not shure whether to post this on this here or on the Ajax controls forum.
I'm building a custom control for Sitefinity. This control uses the RadProgressArea control for visualize the progres of a long running process. Unfortunately I'm unable to make it work correctly. I've used the example code of the ProgressArea control demo page
The progressarea is displayed and hidden correctly, but the updates I set through RadProgressContext.Current are not displayed. I can see the elapsed time counter is being updated and if I use fiddler I can see expected behaviour as the RadUploadProgressHandler.ashx is called. The response from the RadUploadProgressHandler seems to be correct except for the actual values for the progress variables.
What am I doing wrong?
