代码隐藏文件无法识别* .ascx中的控件

I have a QuestionControl.ascx and a QuestionControl.ascx.cs code behind file I copied to a new project. When I build the project any references in the code behind file to controls declared in the ascx gives me this error:

我有一个QuestionControl.ascx和一个QuestionControl.ascx.cs代码隐藏在我复制到新项目的文件后面。当我构建项目时,代码隐藏文件中的任何引用到ascx中声明的控件都会给我这个错误:

'QuestionControl' does not contain a definition for 'rdbtnlstQuestion1' and no extension method 'rdbtnlstQuestion1' accepting a first argument of type 'QuestionControl' could be found (are you missing a using directive or an assembly reference?)

'QuestionControl'不包含'rdbtnlstQuestion1'的定义,并且没有可以找到接受类型'QuestionControl'的第一个参数的扩展方法'rdbtnlstQuestion1'(你是否缺少using指令或汇编引用?)

This is at the top of my *.ascx:

这是我* .ascx的顶部:

<%@ Control Language="C#" AutoEventWireup="true" CodeFile="QuestionControl.ascx.cs" Inherits="QuestionControl" %>

I've also tried CodeBehind:

我也尝试过CodeBehind:

<%@ Control Language="C#" AutoEventWireup="true" CodeBehind="QuestionControl.ascx.cs" Inherits="QuestionControl" %>

This is the top of my class in the codebehind file, it is not contained in a namespace:

这是我在代码隐藏文件中的*,它不包含在命名空间中:

public partial class QuestionControl : System.Web.UI.UserControl
{

5 个解决方案

#1

Try deleting your designer file. VS.NET should recreate it for you when you open the ascx file. I've had problems like this in the past where the designer gets out-of-sync for some reason, and deleting it usually fixes the problem.

尝试删除您的设计器文件。当您打开ascx文件时,VS.NET应该为您重新创建它。我曾经遇到过这样的问题,设计师出于某种原因失去了同步,删除它通常会解决问题。

Another solution is to:

另一个解决方案是:

open your .ascx page in design view

在设计视图中打开.ascx页面

right click anywhere on the page and select Refresh

右键单击页面上的任意位置,然后选择刷新

(.ascx.designer.cs file may need to to be closed while doing refresh for this to work)

(.ascx.designer.cs文件可能需要在刷新时关闭才能工作)

What worked form me was listed on another SO answer and I can't find it so I'm repeating it here.

在我的另一个SO答案中列出了我的作品,我找不到它,所以我在这里重复一遍。

Try deleting your "ReflectedSchemas" folder in

尝试删除您的“ReflectedSchemas”文件夹

C:\Users\YOURUSENAME\AppData\Roaming\Microsoft\VisualStudio\15.0_079f391b\ReflectedSchemas

This worked for me. Sometimes I get the "unrecognized" errors, and I delete this folder again. Many thanks to the OP. Been driving me crazy for years. Now I have no "squiggles" in the HTML and no "red bars" in the code behind (aspx.cs)

这对我有用。有时我会收到“无法识别”的错误,我会再次删除此文件夹。非常感谢OP。一直让我疯狂多年。现在我在HTML中没有“曲线”,后面的代码中没有“红色条”(aspx.cs)

I had problems for example creating a dropdownlist inside a gridview. What I did is creating the ddl outside of the gv until the desinger.cs recognized it and afterwards moved the control inside the gv... hope this helps

我有问题,例如在gridview中创建一个下拉列表。我做的是在gv之外创建ddl,直到desinger.cs识别出来然后将控件移到gv中...希望这有助于

I was having the same issue, the code-behind didn't recognize the controls on the .aspx page. I'm using VS 2012. I right-clicked the project; clicked on Convert to Web Application; and it added all the designer files that weren't there at all before. I rebuilt everything and it's good now.

我遇到了同样的问题,代码隐藏无法识别.aspx页面上的控件。我正在使用VS 2012.我右键单击了该项目;点击转换为Web应用程序;并且它添加了之前根本不存在的所有设计器文件。我重建了一切,现在很好。
