Hello Ravi,

Generally when the Content-Disposition is set to attachment you should always get a prompt asking the user whether to allow the file to be downloaded. However you can try workarounding the behavior by following the suggestions from the below provided resources.
Additionally please note that the problem is not directly related to our controls and is more a general programming issue. That said I recommend researching the MSDN forums for possible alternative solutions.
