I'm requesting .ashx page from Master page client side script (Jquery) which has a code to download a PDF file. When I debug it, I can see the execution of "file download" code but file is not downloading.
$.ajax({
type: "POST",
url: "FileDownload.ashx",
dataType: "html",
success: function (data) { }
} );
public class FileDownload : IHttpHandler
{
public void ProcessRequest(HttpContext context)
{
//context.Response.ContentType = "text/plain";
//context.Response.Write("Hello World");
string fileName = "BUSProjectCard.pdf";
string filePath = context.Server.MapPath("~/Print/");
context.Response.Clear();
context.Response.ContentType = "application/pdf";
context.Response.AddHeader("Content-Disposition", "attachment; filename="+fileName);
context.Response.TransmitFile(filePath + fileName);
context.Response.End();
}
Your file is downloading, but you get it on javascript, on the data
parameter of your call because you call it with Ajax.
You use a handler - so ajax not needed here, and the most easy thing to do using javascript is that:
window.location = "FileDownload.ashx?parametres=22";
or with a simple link as
<a target="_blank" href="FileDownload.ashx?parametres=22" >download...</a>
Ah, and send the parameters via the url, you can not post them that way.
