Visual Studio 2015代码隐藏(codeFile)似乎不在关联的ASPX中定位控件(对象) [英] Visual Studio 2015 Code-Behind (codeFile) does not seem to be locating controls(objects) in associated ASPX
问题描述
我正在用两个页面在Visual Studio 2015中创建一个网站.
I am creating a website in Visual Studio's 2015 with two pages.
我有2个网页(index.aspx和index2.aspx)，两个页面的顶部都有页面控件，它们的角度为CodeFile ="index.aspx.cs".和CodeFile =" index2.aspx.cs".
I have 2 webpages (index.aspx and index2.aspx) both pages have page control at top with their perspective CodeFile="index.aspx.cs" and CodeFile="index2.aspx.cs".
还继承了index和index2.
also Inherits index and index2.
索引页面上有按钮，验证，texbox和标签，index2页面上只有一个标签.
There are buttons, validation, texboxes, and labels on the index page, the index2 page only has a label.
当我转到代码页时，由于某种原因，下拉菜单将灰色显示在第三个框中.
When I go to the code page, for some reason the pull downs gray out the controls in the third box over.
第一选择列表- wk4_site_cs
Fist select list - wk4_site_cs
第二个-索引(通常是列出控件的位置，至少对于VB.NET而言)
second - index (usually this is where the controls are listed, at least for VB.NET)
第三-具有控件，但它们呈灰色显示. 如果我选择一个，我会得到
third - has the controls but they are grayed out. if I select one i get
我看到了另一篇有关此的文章，但是那些解决方案从未奏效，并且适用于VS的较旧版本.我正在使用更新3的2015.
I saw other post about this but those solutions never worked and were for older version of VS. I am using 2015 with update 3.
任何想法如何解决此问题.
any Ideas how to fix this.

推荐答案
您是否尝试过备份项目并使用向导添加新的Web窗体?它应该创建必要的".designer.cs"文件.检查它是否有效，然后移动< html>区域到aspx文件，函数到.cs文件. .designer.cs文件应 自动重新生成.如果您重命名页面(最好在解决方案资源管理器"中完成)或类(可以使用重构"功能完成)重命名，则请确保 CodeBehind 和 Inherits 是正确的，必要时包括名称空间.
Have you tried to back up the project and add a new Web Form using the Wizard? It should create the necessary ".designer.cs" file. Check if it works, then move the <html> area to aspx file and the functions to .cs file. The .designer.cs file should be regenerated automatically. If you rename the page (which is better to do in Solution Explorer) or the class (which can be done using Refactor features), then make sure that CodeBehind and Inherits are correct, including the namespaces if necessary.
似乎它与.designer.cs文件和 CodeBehind 一起使用时效果更好 CodeFile .
Seems that it works better with .designer.cs file and CodeBehind instead of CodeFile.
