Download file from ajaxified control (download dialog not appearing)

[David]

I have several controls which were ajaxified using RadAjaxManager and I'm now trying to download a PDF. I understand
the issues with not being able to use Response.WriteFile (callbacks don't work...full postbacks do). I found
the following link on your site about using the ResponseScripts collection to get around this issue, i.e.,

http://www.telerik.com/help/aspnet-ajax/ajax-download.html

RadAjaxManager1.ResponseScripts.Add(String.Format(@"window.location.href = ""{0}"";", "http://yoursite.com/Your_File"));

This works fine...but the file appears in the existing browser window...I do not get the file download dialog.

Is there a way to add something similar to the following "content-disposition" header (with the attachment attribute)...so the download
file dialog appears?  I need the downloaded file to appear in a separate window.

Response.AppendHeader("content-disposition", "attachment; filename = " + Path.GetFileName(fileName));

Hello David,

The required functionality could not be achieved when the Ajax techniques with registering ResponseScripts is used. I would suggest you to disable the Ajax for the specific download button in order to be able to append content-disposition header as needed.

Thanks Maria...I added,

ajaxManager.set_enableAJAX(

 

false);

 

...to the client-side function that triggers the download and it now works fine.
