asp图表错误 [英] asp chart errors

问题描述

我有一个奇怪的情况使用asp ajax图表控件。我有一个应用程序试图在aspx页面上显示图表。这里是我的web.config的几个片段 -

 < appSettings> 
< add key =ChartImageHandlervalue =storage = file; timeout = 20; dir = c：\temp\;/> 
< / appSettings> 
  

...

 < httpHandlers> 
< add path =ChartImg.axdverb =GET，HEADtype =System.Web.UI.DataVisualization.Charting.ChartHttpHandler，System.Web.DataVisualization，Version = 3.5.0.0，Culture =中性，PublicKeyToken = 31bf3856ad364e35validate =false/> 
< / httpHandlers> 
  

...

 < handlers> 
< remove name =ChartImageHandler/> 
< add name =ChartImageHandlerpreCondition =integratedModeverb =GET，HEADpath =ChartImg.axdtype =System.Web.UI.DataVisualization.Charting.ChartHttpHandler，System.Web。 DataVisualization，Version = 3.5.0.0，Culture = neutral，PublicKeyToken = 31bf3856ad364e35/> 
< / handlers> 
 

当我通过VS2010 IDE运行应用程序时，我得到以下错误尝试显示图表 -

 解析器错误
说明：解析服务此请求所需的资源时发生错误。请查看以下特定解析错误详细信息，并相应地修改源文件。 
 
解析器错误消息：未知的服务器标签'asp：Chart'。 
  

但是，如果我将它部署到我的服务器，似乎无法找到图表其中图像将与红色X一起出现，表示图像不能被找到）。
区别是我从windows xp 32位计算机运行IDE，我部署的服务器是运行IIS 7的64位Server 2008计算机。

有人知道我为什么会有这些问题吗？ / code>部分添加以下内容：

 < add tagPrefix =asp
 namespace = System.Web.DataVisualization，Version = 4.0.0.0，Culture = neutral，PublicKeyToken = 31bf3856ad364e35/> 
  

或者您可以在使用它们的页面上注册控件。

I have a strange situation using asp ajax chart controls. I have an application which is attempting to display a chart on an aspx page. Here are a couple of snippets from my web.config -

<appSettings>
    <add key="ChartImageHandler" value="storage=file;timeout=20;dir=c:\temp\;"/>
</appSettings>

...

<httpHandlers>
    <add path="ChartImg.axd" verb="GET,HEAD" type="System.Web.UI.DataVisualization.Charting.ChartHttpHandler, System.Web.DataVisualization, Version=3.5.0.0, Culture=neutral, PublicKeyToken=31bf3856ad364e35" validate="false"/>
</httpHandlers>

...

<handlers>
    <remove name="ChartImageHandler"/>
    <add name="ChartImageHandler" preCondition="integratedMode" verb="GET,HEAD" path="ChartImg.axd" type="System.Web.UI.DataVisualization.Charting.ChartHttpHandler, System.Web.DataVisualization, Version=3.5.0.0, Culture=neutral, PublicKeyToken=31bf3856ad364e35"/>
</handlers>

When I run the application through the VS2010 IDE, I am getting the following error when trying to display the chart -

Parser Error 
Description: An error occurred during the parsing of a resource required to service this request. Please review the following specific parse error details and modify your source file appropriately. 

Parser Error Message: Unknown server tag 'asp:Chart'.

However, if I deploy it to my server, it seems that the chart cannot be found (an outline where the image would be appears with the red X saying that the image cannot be found). The difference is that I am running the IDE from windows xp 32bit machine, and the server I deploy to is a 64bit Server 2008 machine running IIS 7.

Does anyone have any idea why I might be having these problems? Thanks for any thoughts.

解决方案

In the web.config <controls> section add the following:

<add tagPrefix="asp"
         namespace="System.Web.UI.DataVisualization.Charting"
         assembly="System.Web.DataVisualization, Version=4.0.0.0, Culture=neutral, PublicKeyToken=31bf3856ad364e35"/>      

Or you can register the controls on the page you are using them.
