OK sorry, I got pulled away from this project for a while. At the point I got pulled away was trying to figure out how to do what you asked, Terry, and I think I figured out that at some point ajax uploader was having a problem with the dnn/asp.net name mankling and dnn was losing the file uploading event. At about that point is where I got pulled away.
In any case, I think I may have fixed it. This time, I ended up clearing the ajax uploader out completely, even redownloading it and installing it from scratch in the site. Now, I think I found a line I had not put in my web.config before:
<system.web>
<pages>
<controls>
<add namespace="CuteWebUI" assembly="CuteWebUI.AjaxUploader" tagPrefix="CuteWebUI"/>
</controls>
</pages>
</system.web>
At least for now, it seems to have worked. Does this seem like I am right? I am not an expert in ASP.Net by any means. Still learning.
