asp报告 - document.getElementById（" ReportViewerID"）返回null [英] asp reporting - document.getElementById("ReportViewerID") returns null
问题描述
我无法在IIS7上运行时在ASP.NET网页上呈现ReportViewer。虽然我在使用Visual Studio 2008在调试模式下运行时查看报告没有问题。
我遇到以下javascript错误：
document.getElementById（... ）.Controller'是null或不是对象
请注意：
1）我的网页中没有Ajax控件，因此控制名称被更改或者某些内容......
2）我在添加托管处理程序对话框中添加了以下内容：
请求路径： Reserved.ReportViewerWebControl.axd
类型： Microsoft.Reporting.WebForms.HttpHandler
名称：保留 - ReportViewerWebControl-axd
3）我们已将安全性从itegrated更改为在国际空间站上课，工作正常...
然后重新运行我的IIS 问题 不再存在......
我是，因此确认它为什么在经典模式下工作而不在集成模式下工作？！？
有什么建议吗？！？
问候，

I am Unable to render ReportViewer on ASP.NET Web pages while running on IIS7. While I have no problem viewing your reports when running on debug mode with your Visual Studio 2008.
I encounter the following javascript error:
document.getElementById(...).Controller' is null or not an object
note that:
1) I have no Ajax control in my web page, so that the contro l name is changed or something...
2) I have added at the Add Managed Handler dialog the following :
Request path: Reserved.ReportViewerWebControl.axd
Type: Microsoft.Reporting.WebForms.HttpHandler
Name: Reserved-ReportViewerWebControl-axd
3) we have changed the security from itegrated to classis at the ISS and it worked fine...
and then rerun my IIS and the problem doesn't exists any more...
I am so confuesed why it does work on classic mode and not at the integrated mode?!?
any suggestion please?!?

推荐答案
我 ;认为您看到的错误是因为web.config中缺少HttpHandler条目。确保在< system.webServer>中有一个ReportViewer HttpHandler条目。 web.config的一节，这部分是IIS7特有的。我知道条目应该是这样的：
< system.webServer>
< handlers>
< 添加 名称 = " ReportViewerWebControlHandler " 动词 = " * " path = " Reserved.ReportViewerWebControl .axd " preCondition = " integratedMode " type = " Microsoft.Reporting .WebForms.HttpHandler，Microsoft.ReportViewer.WebForms，Version = 9.0.0.0，Culture = neutral，PublicKeyToken = b03f5f7f11d50a3a " />
< / handlers>
< /system.webServer>
I think the error that you are seeing is because there is a missing HttpHandler entry in the web.config. Make sure you have a entry for the ReportViewer HttpHandler in the <system.webServer> section of the web.config, this section is specifc to IIS7. I beliieve the entry should look something like this:
<system.webServer>
<handlers>
<add name="ReportViewerWebControlHandler" verb="*" path="Reserved.ReportViewerWebControl.axd" preCondition="integratedMode" type="Microsoft.Reporting.WebForms.HttpHandler, Microsoft.ReportViewer.WebForms, Version=9.0.0.0, Culture=neutral, PublicKeyToken=b03f5f7f11d50a3a"/>
</handlers>
</system.webServer>
