body of report not visible

Question

Using Visual Studio 2015 mvc 5 application. I have created an SSRS report with Visual Studio 2012 that does not take any parameters (yet). I used nuget to add ReportViewerForMvc. I went through an online tutorial to create ReportTemplate.aspx etc. I'm using Forms Authentication so I changed my data sources to use a static SQL Login in SSRS. When I run the report manually I get 151 pages. When I run it through the application the toolbar at the top reads 1 of 151 pages. However, I can't see the body of the report and all the buttons on the toolbar are disabled. I've been fiddling with the control properties in the ReportTemplate.aspx.cs (code behind) and the ReportTemplate.aspx but nothing seems to change it.

    protected void Page_Load(object sender, EventArgs e)
    {
        if (!IsPostBack)
        {
            try
            {
                String reportFolder = System.Configuration.ConfigurationManager.AppSettings["SSRSReportFolder"].ToString();
                String reportUri = System.Configuration.ConfigurationManager.AppSettings["SSRSReportUri"].ToString();

                rvSiteMapping.Height = Unit.Pixel(2000);
                rvSiteMapping.ProcessingMode = Microsoft.Reporting.WebForms.ProcessingMode.Remote;

                rvSiteMapping.ServerReport.ReportServerUrl = new Uri(reportUri); // Add the Reporting Server URL 
                rvSiteMapping.ServerReport.ReportPath = String.Format("/{0}/{1}", reportFolder, Request["ReportName"].ToString());
                rvSiteMapping.ServerReport.Timeout = 320000;

                rvSiteMapping.ServerReport.Refresh();

                rvSiteMapping.ShowReportBody = true;
                rvSiteMapping.ShowToolBar = true;
                rvSiteMapping.SizeToReportContent = true;
                rvSiteMapping.Enabled = true;
                rvSiteMapping.Visible = true;
            }
            catch (Exception ex)
            {
                Console.Write(ex.Message);
            }
        }
    }
