Hi, I use report viewer control with IIS 7 (SQL 2008 R2 SSRS). The problem I am facing is, for some users, teh report Viewer is not rendering properly. the Export button and a few other buttons are grayed out. I read a few posts which mentioned that the report Viewer control needs to be explicitly registered with IIS 7. I added the following contents to my application's web.config <add name="ReportViewerWebControlHandler" preCondition="integratedMode" verb="*" path="Reserved.ReportViewerWebControl.axd" type="Microsoft.Reporting.WebForms.HttpHandler, ReportingServicesWebServer, Version=10.0.0.0, Culture=neutral "/> <add name="ReportViewerWebControl" path="Reserved.ReportViewerWebControl.axd" verb="*" type="Microsoft.Reporting.WebForms.HttpHandler" resourceType="Unspecified" /> But this does not seem to be helping. The report Viewer does not still render properly. Any help in this regard is much appreciated. Thanks.

Hi Viva1, The issue is documented at http://blogs.msdn.com/b/webtopics/archive/2009/02/10/report-viewer-toolbar-does-not-render-properly-on-iis-7-0.aspx. After adding the Http handler entry, reset your IIS 7.0. If the issue is still not solved, post your web.config here for further troubleshooting. thanks, Jerry

Hi Jerry, thanks so much for your response. I referred to the link and found that it referred to the 9.0.0.0 Version of Report Viewer Control. I use SQL server 2008. SO, I cahnged the version to 10.0.0.0 and the corresponding Public key token. It still did not work. I tried adding the same content that was given in the post and it did not work either. The surprising part is it does not work only for a specific set of users. It works for a few of them. PLease let me know if you have any thoughts on this. Thanks.

I too face continued problems with the reportviewer which works fine in vs2010 but will not render properly on IIS7 on a 2008 production server. The report renders but all controls are greyed out. Have been trying everything for few days. Here is my anonymised web.config. Would be very greatful if you can spot anything obvious.
