Report Viewer Control missing Header Icons

Hi,

In IIS 7, we need to make sure we configurate the ReportViewer handler.

You can follow these steps:

• Open Internet Information Services (IIS) Manager and select your Web application.
• Under IIS area, double-click on Handler Mappings icon.
• At the Action pane on your right, click on Add Managed Handler.
• At the Add Managed Handler dialog, enter the following:
  Request path: Reserved.ReportViewerWebControl.axd
  Type: Microsoft.Reporting.WebForms.HttpHandler
  Name: Reserved-ReportViewerWebControl-axd
• Click OK.
