  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.Clear();
      Response.ClearHeaders();
      Response.AddHeader("Content-Disposition", "filename=\"\"" + "caseoverview" + ".pdf" + "");
      Response.ContentType = MimeTypes.ApplicationPdf;
      Response.OutputStream.Write(data1, 0, Convert.ToInt32(stream.Length));
      Response.Flush();
      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>
                  <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>
                      <div class="col-md-2 col-sm-6">
                          <button class="btn btn-submit btn-block" type="reset">Reset</button>
                      </div>
                  </div>
              }

  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));
              w.document.write(dataq.responseText);
              w.document.close();
      }
      }
  

  
  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.
