Microsoft distributes Microsoft SQL Server 2008 R2 fixes as one downloadable file. Because the fixes are cumulative, each new release contains all the hotfixes and all the security fixes that were included with the previous SQL Server 2008 R2 fix release.
Consider the following scenario:
You run Microsoft SQL Server 2008 R2 Reporting Services (SSRS) in the SharePoint Integrated mode.
You integrate a Microsoft SharePoint 2010 site with SSRS 2008 R2.
You run the SharePoint site in debug mode.
You deploy a report to a document library on the SharePoint site. The report contains a drillthough report.
You add a Report Viewer Web part to a SharePoint page to display the report.
You click the drillthrough link to open the drillthrough report in the SharePoint page.
In this scenario, you receive an error message that resembles the following:
Message: Sys.ArgumentNullException: Value cannot be null. Parameter name: panelsCreated Line: 129 Char: 12 Code: 0 URI: http://ServerName/ScriptResource.axd?d=eIta46jBcyLp_5IiiP-xPYuM8iTgFWIJYJ1hdQQhytwzGZrxHUy3xfhvGgvjnG17BofUwEtaQ7Yik54n3MpmW77MX1gjt2yj-Zgalo8nheYxZrca6zgrx0VoNFUyBrAw0&t=ffffffffec2d9970
Note This issue usually occurs when you use the SharePoint Integrated mode. Additionally, this issue may also occur when you use the Native mode if the following conditions are true:
You use the WebForms ReportViewer control that was released together with Visual Studio 2010 in a webpage.
You set the ShowToolbar property of the control to False.
You run the website in debug mode.
You configure some elements of the page to listen to the PageRequestManager.pageLoaded event.
This issue occurs because the ReportViewer control does not generate the report correctly.
