图表控件未显示在主机中！ [英] the chart control is not shown in host!

问题描述

我在网站上使用图表控件(通过连接到数据库).
它在本地主机上工作良好，但在服务器上不起作用.
使用此web.config，将运行页面，但未显示图表:

当"httphandlers"标记未注释时，整个站点将无法运行！

错误:
HTTP错误500.23-内部服务器错误
检测到在集成托管管道模式下不适用的ASP.NET设置.

when the "httphandlers" tag isnt comment,the whole of site is not run!

error :
HTTP Error 500.23 - Internal Server Error
An ASP.NET setting has been detected that does not apply in Integrated managed pipeline mode.

推荐答案

此错误500.23转换为-ASP.NET httpHandlers配置不适用在托管管道模式下.

检查IIS中的httpHandlers配置.尝试以下操作:

1.打开服务器管理器
2.选择角色">"Web服务器(IIS)">"IIS管理器">选择服务器">分配池"
3.选择您的asp.net应用程序正在运行的应用程序池，在>点击右侧窗格中的高级设置"下.
4.在高级设置">常规">受管管道模式"下，选择经典"
5.回收应用程序池并测试您的应用程序.

This error 500.23 translates to - An ASP.NET httpHandlers configuration does not apply in Managed Pipeline mode.

Check the httpHandlers configuration in IIS. Try following:

1. Open Server Manager
2. Select Roles>Web Server (IIS)>IIS Manager>Select the Server>Applocation Pools
3. Select the appPool that your asp.net app is running under>Click on ''Advanced Settings'' from the right hand pane.
4. Under Advanced Settings>General>Managed Pipeline Mode, select "Classic"
5. Recycle app pool and test your app.
