I have a grid that allows users to insert/update/delete products.  I have a radasynupload control that allows the users to upload pictures to the server.  when the save button is clicked on the grid, the code then gets the image and saves it to like an "images" folder. the folder have read and write permissions. the app_data folder also has read and write permission.  any help will be appreciated.   my site is on a shared web hosting.

Hi Ropate Kumo,

This turned out to be an intermittent issue with RadAsyncUpload, which we have just fixed. The issue is triggered when RadAsyncUpload is used in medium trust scenarios. The fix is going to e available together with the next service pack, which is scheduled for the next week.

Kind regards,
