C#VS2005使用ReportViewer元件

當環境在Win Server 2008 x64 + IIS 7 時

IE右下角會出現一個 ! 驚嘆號的 ReportViewer 是null或不是一個物件 的 錯誤訊息!

Resolution:

<一>可以在IIS上設定

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.

<二>在webconfig上加

 <system.webServer>

    <handlers>

      <add name=": Reserved-ReportViewerWebControl-axd" path="Reserved.ReportViewerWebControl.axd" verb="*" type="Microsoft.Reporting.WebForms.HttpHandler" resourceType="Unspecified" preCondition="integratedMode" />

    </handlers>

  </system.webServer>

以上解法就OK啦~
