How do I render a remote ReportViewer aspx page in MVC4?

Question

I\'m working on an MVC4 application that needs to render a remote report from SSRS using the ReportViewer. With help from this forum, I\'ve managed to get the page to render

Answer 1

In the end, I ended up having to ditch both my original answer and the callbacks criteria due to the unacceptable security risks. In my case, I wrote controller code rendering the report as HTML to a byte array and from there to a FileContentResult that MVC was kind enough to render as a static HTML page. Exporting as PDF, Excel, or any other options will eventually be implemented in a similar method by changing the Render parameter from HTML4.0 to whatever is appropriate (PDF,XLS) and the MIME type. This approach works with SQL Server 2008R2 and beyond. I haven't tried it with previous versions of SQL Server.

[OutputCache(Duration = 120, VaryByParam = "id")]
public ActionResult ExportHTML(int id)
{
    // we need to add code to check the user's access to the preliminary report.
    // Also need to consolidate code between ExportHTML and ExportPDF.
    var userid = ;
    var password = ;
    var domain = ;
    IReportServerCredentials irsc = new myApp.Models.CustomReportCredentials(userid,
        password, domain);
    var parametersCollection = new List();
    parametersCollection.Add(new ReportParameter("Snapshot", id.ToString(), false));
    ReportViewer rv = new Microsoft.Reporting.WebForms.ReportViewer();
    rv.ProcessingMode = ProcessingMode.Remote;
    rv.ServerReport.ReportServerCredentials = irsc;
    rv.ServerReport.ReportPath = ;
    rv.ServerReport.ReportServerUrl = new Uri("http://localhost/ReportServer");
    rv.ServerReport.SetParameters(parametersCollection);

    rv.ServerReport.Refresh();
    byte[] streamBytes = null;
    string mimeType = "";
    string encoding = "";
    string filenameExtension = "";
    string[] streamids = null;
    Warning[] warnings = null;

    streamBytes = rv.ServerReport.Render("HTML4.0", null, out mimeType, out encoding,
                                         out filenameExtension, out stream ids,
                                         out warnings);
    var HTMLReport = File(streamBytes, "text/html");
    return HTMLReport;
}
