Hi Terry,

 

Thanks for that.  I did have a look at the MVC stuff, but as my code isn't an MVC application, I couldn't work out how to apply it to my problem. 

 

Rather than thinking MVC, it's more that I'm trying to use an AJAX PageMethod instead of an UpdatePanel to save the file somewhere.

 

It's all working except for (and this is quite the show-stopper) the file disappearing somewhere after upload (the progress bar indicates it's gone up to the server somewhere) and before calling my AJAX PageMethod.  I thought perhaps calling "return false;" on the _CuteWebIO_AjaxUploader_OnPostback() is causing it not to write the file, but I've got an "alert()" call in the function and if I search the server disk while the alert box is still displayed (i.e. before the "return false;" statement) the file still doesn't appear to be anywhere.

 

Thoughts?
