My requirement is to open a file in a new window/tab upon clicking the download link. The file is always downloaded despite setting the content disposition to 'inline' as suggested in the below post.
How to open PDF file in a new tab or window instead of downloading it (using asp.net)?
My HTTP response is
HTTP/1.1 200 OK
Cache-Control: private, s-maxage=0
Content-Type: application/octet-stream
Server: Microsoft-IIS/7.5
X-AspNetMvc-Version: 5.2
content-disposition: inline;filename=FileName.pdf
X-AspNet-Version: 4.0.30319
X-Powered-By: ASP.NET
Content-Length: 141954
My Controller Action is as below -
public async Task<FileContentResult> Index(string fileName)
{
byte[] document = await getFileContent("SomePathForTheFile");
HttpContext.Response.AddHeader("content-disposition", "inline;filename=" + document.FileName);
return File(document, "application/octet-stream");
}
Suggestions to make the file open automatically in a new tab/window instead of just being downloaded would be of great help! Thanks!
Found the answer.
2 things have to be done for the file to open in a new window -
1.content-disposition must be set to inline
2.the content type should be set to the type corresponding to the file being downloaded -
application/pdf - for pdf files
application/xml - for xml files
application/vnd.ms-excel - for xls files and so on.
Try the following code.
@Html.ActionLink("Home","Index",null,new { @target="_blank" })
Since we are returning to the view mode, there is no need to mention about header response
public async Task<FileContentResult> Index(string fileName)
{
byte[] document = await getFileContent("SomePathForTheFile");
return File(document, "application/octet-stream");
}
