i have a problem in uploading files via RadAsyncUpload when i open the page that contains the telerik upload controls
the following error rises -->
RadAsyncUpload does not have permission to write files in the TemporaryFolder. In Medium Trust scenarios, the TemporaryFolder should be a subfolder of the Application Path.
in localhost working fine but in my website does not work ,
so i contacted to the host provider and asked to set full permission to App_Data an the Target folder and sub folders so they set the permission and still i get the above error ,
then i set UseApplicationPoolImpersonation to True and impersonate to true in web.config but still no hope same error,
what can i do to fix this error
note: before the host provider update iis to 10 the upload was working.
