I'm having real trouble getting the Ajax Uploader with all the persistedfile logic to integrate into my existing site. I have the following page / control hierarchy as discussed in this post http://cutesoft.net/forums/thread/37997.aspx
AjaxTabContainer (Ajax Control Toolkit)
AjaxTabPanel (Ajax Control Toolkit)
All functionality is working with uploading and saving a picture however after the image is uploaded the complete page posts back and my Tab Container reloads the with the first Tab Panel selected, the Ajax Uploader is in the last tab (the fourth one). Any ideas as it really isn't providing the nice ajaxy partial page post back feel. I have tried moving the control so it's not in the AjaxTabContainer but get the same issue.
