I am having an issue with my reportviewer where nothing is visible, not even

  • 0

I am having an issue with my reportviewer where nothing is visible, not even the control. If I add other content, it shows, but the reportviewer is not. I am using the 9.0.0.0 version of the control with SSRS 2005 inside an MVC 2.0 application. I have built and deployed the report to the server. I have confirmed by looking on the report server and running it there.

  1. My app is MVC 2.0
  2. I have added a regular webforms page into the root of the website. I put it in a form, runat=server, and enabled viewstate
  3. I have added the .aspx routing exception
  4. My code behind is set up similarly to every example I can find
  5. My webconfig is configured (maybe that is where my issue is)
  6. I set up a manual test by forcing the correct values in and I get the same blank page.
  7. I have a reference to the 9.0.0.0 versions of Microsoft.ReportViewer.WebForms and Microsoft.ReportViewer.Common and as you can see my web.config matches my references.

The page appears white – no control is visible. No errors are thrown. As I remembered it, there should at least be a blank Reportviewer control on the page, however there isn’t anything there at all.

A few other oddities – If I remove the parameter setting, no error occurrs. I also added code to send in credentials, but that did not work, even when sending in the credentials for the administrator account.

Report.aspx

<%@ Page Language="C#" AutoEventWireup="true" ViewStateMode="Enabled" CodeBehind="Report.aspx.cs" Inherits="MySite.Web.Report" %>

<%@ Register Assembly="Microsoft.ReportViewer.WebForms, Version=9.0.0.0, Culture=neutral, PublicKeyToken=b03f5f7f11d50a3a"

<html>
<body>
<form id="form1" runat="server">

</form>

</html>

Routing Exceptions

routes.IgnoreRoute("{resource}.axd/{*pathInfo}");
routes.IgnoreRoute("{resource}.aspx/{*pathInfo}");

Code Behind

protected void Page_Load(object sender, EventArgs e)
{
    var qs = ReportQueryString.Parse(Request.QueryString["R"]);

    reportViewer.ServerReport.ReportServerUrl = ConfigurationHelper.Reports.ReportServerUrl;
    reportViewer.ServerReport.ReportPath = String.Format(ConfigurationHelper.Reports.ReportPath, qs.ReportName);

    var result = from p in qs.Parameters
                    select new ReportParameter(p.Key, p.Value);

    reportViewer.ServerReport.SetParameters(result);
    reportViewer.ServerReport.Refresh();
}

As requested, here is the page source. On a side note, I am using Chrome, but I did try IE with the same result.

    In the event anyone else sees this, my problem was in how I defined the control on my page. I had to set the ProcessingMode attribute and then it worked like a champ.

    <rsweb:reportviewer ID="reportViewer" Width="100%" EnableViewState="True" 
    runat="server" ProcessingMode="Remote" />

    Hopefully someone else won’t spend as long as I did trying to troubleshoot this issue.
