名称为“控制”并不在当前上下文中存在 [英] The name 'control' does not exist in the current context
本文介绍了名称为“控制”并不在当前上下文中存在的处理方法，对大家解决问题具有一定的参考价值，需要的朋友们下面随着小编来一起学习吧！
问题描述
我有对我的工作，我已经继承的，一旦抓住从资源库和建筑的源网站上有错误的麻烦，然后清除了几个引用错误，我仍然得到了1000这个实例错误：
名称'pnlDetails'不在当前情况下存在（与任何我控制的名字替换'panelDetails'）
这是什么似乎表明的是引用的服务器端控件未声明的页面上，或者没有RUNAT =服务器在其中，但实际上他们做的。它也可能是属性不匹配的继承的一个问题，但它确实。我已搜查计算器和之前看到了这个问题，虽然尝试一些提到的解决方案后，他们并没有帮助。我没有任何设计文件我的网页。下面是从ASPX和aspx.cs页面code的一些片段。 （节录了一些信息，以保护客户隐私）
我的问题是，我为什么不能引用在服务器端控制我？ paneldetails'，'rpAddresses等等？

解决方案
感谢您的答案的人，我也尝试了一些这些事情。
- 您希望在aspx.cs访问每个控件应该有=服务器
他们做
<醇开始=2>
添加上述标记之后构建解决方案
如果您要访问中继器的项目模板中定义的控制你
可以在里面转发的事件通过把一个循环读取所以只有做
中继器的所有项目
他们
右键点击页面你在哪里得到的错误，然后点击
转换成Web应用程序...这将解决您的错误。在我的IDE没有这样的选择，况且我认为这将是整个项目，不是我转换页面。
检查是否这是一个Web应用程序项目或网站
项目。网站项目将使用的的codeFILE属性
@ Page指令，而是一个Web应用程序项目不会。如果它是
尝试编译为Web应用程序项目，您将收到
这些错误，因为Web应用程序项目预计设计师文件
除了在.aspx和.aspx.cs文件。设计师包含了所有
对照定义，从而允许您参考
他们在正确的codebehind（Web应用程序使用codeBehind而不是
codeFILE属性也一样）。显然，然后我的项目是一个网站，而不是一个Web应用程序，因为它包含了codeFile的属性。还有，我没有设计文件，因此，这是有道理的。
原来我试图编辑在VS2008开发，使用VS2013的解决方案，此后便发生了很多变化。虽然没有在这里解决问题，修复是创建一个新的VS2013解决方案，并导入文件，它的所有工作作为目前打算，谢谢你。
I am having trouble with an error on a site I am working on that I've inherited, upon grabbing the source from the repository and building, then clearing out a few reference errors, I am still getting over 1000 instances of this error:
The name 'pnlDetails' does not exist in the current context (replace 'panelDetails' with any of my control names).
what this would seem to indicate is that the controls referenced server side are not declared on the page, or don't have runat=server in them, but in fact they do. it could also be a problem of the inherits attribute not matching, but it does. I have searched stackoverflow and seen this question before, though after trying some of the solutions mentioned, they did not help. I do not have any designer files for my pages. Below are some snippets of code from the aspx and aspx.cs pages. (some information redacted to protect client privacy)
My question is, why can't i reference my controls on the server side? 'paneldetails', 'rpAddresses' etc.?

解决方案Thanks for the answers people, I did try some of these things.
- Every control which you wish to access in aspx.cs should have runat="server"
they do
Build your solution after adding the above tag
If you wish to access the control defined inside the item template of repeater you can do so only inside repeater events for by putting a loop reading all items of repeater
they are
Right click on the page where you are getting the error and click on convert to web application... That will solve your error.
no such option in my IDE, besides I think it would be the whole project, not a page that I convert.
Check to see if this is a web application project or a website project. A website project would use the CodeFile attribute of the @Page directive, but a web application project wouldn't. If it's trying to compile as a web application project, you would receive these errors because a web application project expects a designer file in addition to the .aspx and .aspx.cs files. The designer contains all the control definitions which in turn which allows you to reference them properly in codebehind (web application uses CodeBehind and not CodeFile attribute as well).
apparently then my project is a website, not a web application, as it includes the codefile attribute. also, I don't have designer files, so this makes sense.
Turns out I am trying to edit a solution developed in VS2008, using VS2013, and a lot has changed since then. While the issue was not resolved here, the fix was to create a new VS2013 solution and import the files, it's all working as intended now, thank you.
