Display PDF stream returned from controller in new window RRS feed

  • Question

  • I am working on a project and I need to display a pdf in a new tab, I have a controller which gets the pdf from a reporting service as a byte[].

        var data = Search(search_info);
        var stream = new MemoryStream(data, 0, data.Length, true, true);    
        Response.AddHeader("Content-Disposition", "filename=\"\"" + "caseoverview" + ".pdf" + "");
        Response.ContentType = MimeTypes.ApplicationPdf;
        Response.OutputStream.Write(data1, 0, Convert.ToInt32(stream.Length));
        return new FileStreamResult(stream, "application/pdf");

    I am using Ajax to call the controller:

      @using (Ajax.BeginForm("Search", "Controller", null,
                    new AjaxOptions
                        HttpMethod = "post",
                        OnComplete = "OnCompleteMethod",
                        OnFailure = "OnFailtureMethod"
                    <div id="query-filter" class="filters">
                        @Html.Partial("QueryFilter", Model)
                    <div class="row">
                        <div class="col-md-2 col-sm-6 col-md-offset-8">
                            <button class="btn btn-submit btn-block" type="submit">Find</button>
                        <div class="col-md-2 col-sm-6">
                            <button class="btn btn-submit btn-block" type="reset">Reset</button>

    And the javascript for the success method is:

     function OnCompleteMethod(dataq, status) {
            if (status === "success") {
                var w = window.open("data:application/pdf, " + escape(dataq.responseText));

    And this is what I am getting in the new tab:

    Can someone please help me with this problem, and explain to me what I am doing wrong or what I am missing from the solution.

    Thank you so much.
