File download from ajaxified grid

[Robert]

Hi,

I have a LinkButton which is embedded in a NestedView of a RadGrid which is Ajax enabled (using an AjaxManagerProxy).

On click on the LinkButton a file should be downloaded. This is the code I use for download:

Response.Clear();
Response.AddHeader("Accept-Ranges", "bytes");
Response.AddHeader("Connection", "Keep-Alive");
Response.AddHeader("Content-Disposition", "attachment; filename=" + doc.FileName);
Response.AddHeader("Content-Length", doc.FileSize.ToString());
Response.ContentType = doc.MimeType;
Response.BinaryWrite(doc.Content.ToArray());
Response.End();

 

This code works perfectly if the grid is not ajax enabled. Is there a way to make it working in an ajax enabled grid?

Many thanks in advance for any suggestions.

Best regards,

Robert

Hi Robert,

Download and Upload functionality cannot work using AJAX calls. This is a limitation of the XmlHttpRequest component, used in all AJAX frameworks for asynchronous calls to the application. In order to download or upload a file your application must perform a full page postback.
