Default Imar: Chp 14 - ManagePhotoAlbum.aspx


Does your published site use AJAX at: http://aspnet4.planetwrox.com/Manage...otoAlbumId=145

PROBLEM: on my ManagePhotoAlbum.aspx page, when I DON'T USE AJAX, both the delete and insert works fine ... however, when I use AJAX on this page, the delete works but the insert doesn't find the image file ... it triggers the "Select a valid .jpg" error message on the custom validation ...

No it doesn't. FileUpload controls don't work out of the box inside an UpdatePanel. That's why you're seeing your files show up as nothing.
