Upgrading To Report Viewer 2010
Visual Studio 2010 ships with updated ReportViewer controls which Brian Hartman discusses in his blog. One issue I recently run into with the Visual Studio 2008 ReportViewer ASP.NET control with a chart configured for a dynamic height (DynamicHeight property) where the chart image wouldn’t size properly. I found that the issue got fixed in the Visual Studio 2010 ReportViewer. However, in my case we weren’t ready to move to Visual Studio 2010 yet. This is what I had to do to upgrade the web application to use the Visual Studio 2010 ReportViewer control:
- Install the Report Viewer 2010 redistributable from http://www.microsoft.com/downloads/details.aspx?FamilyID=a941c6b2-64dd-4d03-9ca7-4017a0d164fd&displaylang=en. The setup program will install the Visual Studio 2010 ReportViewer assemblies in GAC as version 10.0.0.0 assemblies.
- Updated the web page as follows (changes in bold):
<%@ Page language=”c#” Codefile=”Demo.aspx.cs” AutoEventWireup=”false” Inherits=”Prologika.Demo” %>
<%@ Register Assembly=”Microsoft.ReportViewer.WebForms, Version=10.0.0.0, Culture=neutral, PublicKeyToken=b03f5f7f11d50a3a” Namespace=”Microsoft.Reporting.WebForms” TagPrefix=”rsweb” %>
<!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 runat=”server”>
<title>Demo</title>
</head>
<body>
<form id=”form1″ runat=”server”>
<div>
<asp:ScriptManager ID=”ScriptManager1″ runat=”server”></asp:ScriptManager> <!–Required for AJAX –>
<rsweb:ReportViewer ID=”reportViewer” runat=”server” Height=”100%” Width=”100%” Font-Names=”Verdana” Font-Size=”8pt”
ProcessingMode=”Remote” InteractiveDeviceInfos=”(Collection)” WaitMessageFont-Names=”Verdana” WaitMessageFont-Size=”14pt”>
</rsweb:ReportViewer>
</div>
</form>
</body>
</html>
- In web.config, replace all 9.0.0.0 version references to Report Viewer to 10.0.0.0.
Of course, if you have Visual Studio 2010, it will take of care of making the required changes for you. Finally, by upgrading to the 2010 ReportViewer as an added bonus besides fixing the dynamic height issue, you will also get the new AJAX support which eliminates page reposts and improves the end user experience.
