该名称在当前上下文中不存在 [英] The name does not exist in the current context

问题描述

我在asp.net 3.5应用程序中拥有一个主页，并且有一些控件和jquery东西.我尝试访问代码隐藏中的控件，它说:

I have a masterpage in my asp.net 3.5 application and I have some controls and jquery stuff. I try to access the controls in codebehind and it says :

The name 'DrpStates' does not exist in the current context  

为什么无法在代码隐藏中访问它?

Why it is not accessible in codebehind ?

推荐答案

当您在文件后面创建代码时，ASP.NET还将自动生成一个设计器文件(紧邻该文件).在该设计器文件中，所有控件均已初始化并加载.有时(由于未知原因)在创建新控件时，它无法重新初始化设计器文件，并且您无法在文件后置代码中访问该控件.

When you create a code behind file, ASP.NET also automatically generates a designer file (which is right next to it). In that designer file all the controls are initialized and loaded. Sometimes (for reasons unknown) when you create a new control, it fails to re-initialize the designer file and you can't get access to the control in the code behind file.

尝试执行此操作>

1. 删除设计器文件(右键单击>删除)
2. 右键单击aspx文件>转换为Web应用程序

现在应该工作
