Hi,

I am getting the same issue. The reportviewer opens but inside it comes written "Entry Point Not Found". I have also checked the assembly and it has only one file.

<%@ Register Assembly="Telerik.ReportViewer.WebForms, Version=4.1.10.921, Culture=neutral, PublicKeyToken=a9d7983dfcc261be" Namespace="Telerik.ReportViewer.WebForms" TagPrefix="telerik" %>

<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">

<html xmlns="http://www.w3.org/1999/xhtml" >

<head id="Head1" runat="server">

<title>Untitled Page</title>

</head>

<body>

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

<div>

<asp:Button ID="Button1" runat="server" Text="Print Report client-side" OnClientClick="PrintReport(); return false;" />

<asp:Button ID="Button2" runat="server" Text="Print Report server-side"/>

<br />

<telerik:ReportViewer ID="ReportViewer1" runat="server" Height="488px" Width="779px">

</telerik:ReportViewer>

<script type="text/javascript">

function PrintReport()

{

<%=ReportViewer1.ClientID %>.PrintReport();

}

</script>

</div>

</form>

</body>

</html>

and cs code is:

using System;

using System.Collections.Generic;

using System.Linq;

using System.Web;

using System.Web.UI;

using System.Web.UI.WebControls;

using Reports;

using System.Drawing.Printing;

namespace iCAT.Web.Reports

{

public partial class TestReport : System.Web.UI.Page

{

public List<object> ReportDataSource { get; set; }

protected void Page_Load(object sender, EventArgs e)

{

rptTest report = new rptTest();

if (Session["Report_DataSource"] != null)

{

ReportDataSource = (List<object>)Session["Report_DataSource"];

}

report.DataSource = ReportDataSource;

ReportViewer1.Report = report;

}
