Hi,

I did a ajax call using jquery to a handler. In the handler's response I write the context type and save a pdf file. Now in the jquery I have to open the pdf file. I used jquery file download plugin. But it doesn't work for me. Plz help me, to complete this task.

JQuery:

JavaScript

function CallHandler() {
                $.ajax({
            url: "iss_report.ashx",
            contentType: "application/json; charset=utf-8",
            success: OnComplete,
            error: OnFail
        });
        return false;
    }
    function OnComplete(result) {
           $.fileDownload(result);
    }
    function OnFail(result) {
        alert('Request failed');
    }

In handler:

C#

public class iss_report : IHttpHandler {
    public iss_report()
    {
    }

    public void ProcessRequest (HttpContext context) {
  Workbook wb= new Workbook();

        context.Response.SetCookie(new HttpCookie("fileDownload", "true") { Path = "/" });
        context.Response.ContentType = "application/pdf";
        invoicebook.Save(context.Response, "mybook.pdf", ContentDisposition.Attachment, new PdfSaveOptions());
    }
 
    public bool IsReusable {
        get {
            return false;
        }
    }

Why did you tag your question C++. C++ is a whole different ball of wax from C#.

I used a plugin by referring this link(http://johnculviner.com/post/2012/03/22/Ajax-like-feature-rich-file-downloads-with-jQuery-File-Download.aspx).
In the plugin they used iframe. The file to be placed in the hidden iframe, because of that it shows the file download dialog box. The last code which i post, has some error. I directly passed the response get from the handler.
Now I changed the code like this.
JQuery:
function CallHandler() {
$.ajax({
url: "iss_report.ashx",
contentType: "application/json; charset=utf-8",
success: OnComplete,
error: OnFail
});
return false;
}
function OnComplete(result) {
$.fileDownload('report/report.PDF');
}
function OnFail(result) {
alert('Request failed');
}
Handler:
public class iss_report : IHttpHandler {
public iss_report()
{
}

public void ProcessRequest (HttpContext context) {
Workbook wb= new Workbook();
string file = ConfigurationManager.AppSettings["pdfreportlocation"].ToString() + "\\report.PDF";
context.Response.SetCookie(new HttpCookie("fileDownload", "true") { Path = "/" });

invoicebook.Save(file);
}

public bool IsReusable {
get {
return false;
}
}
Every steps are working fine.But I didn't get file download dialog box or any error message. In the status bar a message blink for a second that start downloading... But nothing happened.
