How can I use a reportviewer control in an asp.net mvc 3 razor view?
I'm trying to use a reportviewer control, within a razor view, in the mvc 3 framework. The online documentation talks of drag and drop. Any suggestion on how to insert it into the view.
Answer
The following solution works only for single page reports. Refer to comments for more details.
ReportViewer is a server control and thus can not be used within a razor view. However you can add a ASPX view page, view user control or traditional web form that containing a ReportViewer into the application.
You will need to ensure that you have added the relevant handler into your web.config.
If you use a ASPX view page or view user control you will need to set AsyncRendering to false to get the report to display properly.
Update:
Added more sample code. Note there are no meaningful changes required in Global.asax.
Web.Config
Mine ended up as follows:
<?xml version="1.0"?>

Controller
The controller actions are very simple.
As a bonus the File() action returns the output of "TestReport.rdlc" as a PDF file.
using System.Web.Mvc;
using Microsoft.Reporting.WebForms;
...
public class PDFController : Controller
{
public ActionResult Index()
{
return View();
}
public FileResult File()
{
ReportViewer rv = new Microsoft.Reporting.WebForms.ReportViewer();
rv.ProcessingMode = ProcessingMode.Local;
rv.LocalReport.ReportPath = Server.MapPath("~/Reports/TestReport.rdlc");
rv.LocalReport.Refresh();
byte[] streamBytes = null;
string mimeType = "";
string encoding = "";
string filenameExtension = "";
string[] streamids = null;
Warning[] warnings = null;
streamBytes = rv.LocalReport.Render("PDF", null, out mimeType, out encoding, out filenameExtension, out streamids, out warnings);
return File(streamBytes, mimeType, "TestReport.pdf");
}
public ActionResult ASPXView()
{
return View();
}
public ActionResult ASPXUserControl()
{
return View();
}
}
ASPXView.apsx
The ASPXView is as follows.
<%@ Page Language="C#" Inherits="System.Web.Mvc.ViewPage<dynamic>" %>
<%@ Register Assembly="Microsoft.ReportViewer.WebForms, Version=10.0.0.0, Culture=neutral, PublicKeyToken=b03f5f7f11d50a3a"
Namespace="Microsoft.Reporting.WebForms" TagPrefix="rsweb" %>
<!DOCTYPE html>
<html>
<head runat="server">
<title>ASPXView</title>
</head>
<body>
<div>
<script runat="server">
private void Page_Load(object sender, System.EventArgs e)
{
ReportViewer1.LocalReport.ReportPath = Server.MapPath("~/Reports/TestReport.rdlc");
ReportViewer1.LocalReport.Refresh();
}
</script>
<form id="Form1" runat="server">
<asp:ScriptManager ID="ScriptManager1" runat="server">
</asp:ScriptManager>
<rsweb:reportviewer id="ReportViewer1" runat="server" height="500" width="500" AsyncRendering="false"></rsweb:reportviewer>
</form>
</div>
</body>
</html>
ViewUserControl1.ascx
The ASPX user control looks like:
<%@ Control Language="C#" Inherits="System.Web.Mvc.ViewUserControl" %>
<%@ Register Assembly="Microsoft.ReportViewer.WebForms, Version=10.0.0.0, Culture=neutral, PublicKeyToken=b03f5f7f11d50a3a"
Namespace="Microsoft.Reporting.WebForms" TagPrefix="rsweb" %>
<script runat="server">
private void Page_Load(object sender, System.EventArgs e)
{
ReportViewer1.LocalReport.ReportPath = Server.MapPath("~/Reports/TestReport.rdlc");
ReportViewer1.LocalReport.Refresh();
}
</script>
<form id="Form1" runat="server">
<asp:ScriptManager ID="ScriptManager1" runat="server"></asp:ScriptManager>
<rsweb:ReportViewer ID="ReportViewer1" runat="server" AsyncRendering="false"></rsweb:ReportViewer>
</form>
ASPXUserControl.cshtml
Razor view. Requires ViewUserControl1.ascx.
@{
ViewBag.Title = "ASPXUserControl";
Layout = "~/Views/Shared/_Layout.cshtml";
}
<h2>ASPXUserControl</h2>
@Html.Partial("ViewUserControl1")
