动态在asp.net网站中加载用户控件（ascx） [英] Dynamically Load a user control (ascx) in a asp.net website

问题描述

我正在尝试在asp.web站点中动态加载用户控件。但是由于asp.net网站项目的设置（我想），我无法访问达到用户控件的类型定义。

我收到一条消息说我的类HE_ContentTop_WebControl1是：他的类型或命名空间名称'HE_ContentTop_WebControl1'找不到（你缺少一个using指令或程序集引用？）

任何想法如何这可以做到工作吗？我尝试使用命名空间，但在我看来，asp.net网站默认情况下不能使用命名空间。我会对非命名空间方法感兴趣。

TIA

 公共部分类HE_Default：
系统.Web.UI.Page {
 
 protected void Page_Load（object sender，EventArgs e）
 {
 var control =（HE_ContentTop_WebControl1）Page.LoadControl（〜/ ContentTop / WebControl1的.ascx）; 
} 
} 
  

解决方案

假设控件存在于与您的Web项目相同的程序集中，您需要在.aspx文件中添加引用指令，

例如：

 <％@ Reference Control =〜/ Controls / WebControl1.ascx>请记住，智能感知通常需要几分钟（或有时是一个构建）来选择这个。 。
 
I am trying to dynamically load a user control in an asp.web site. However due to how asp.net websites projects are setup (I think), I am not able to access reach the type definition of the user control.

I get a message saying that my class HE_ContentTop_WebControl1 is: he type or namespace name 'HE_ContentTop_WebControl1' could not be found (are you missing a using directive or an assembly reference?)

Any idea how this could be made to work ? I have attempted using namespace but it seems to me that asp.net websites are not designed to work with namespaces by default. I would be interested in a non namespace approach. 

TIA
public partial class HE_Default :
     System.Web.UI.Page   {  

    protected void Page_Load(object sender, EventArgs e)  
    {  
       var control = (HE_ContentTop_WebControl1)Page.LoadControl("~/ContentTop/WebControl1.ascx");         
    }
}

解决方案
Assuming the control exists in the same assembly as your web project, you need to add a reference directive in your .aspx file,

e.g:
<%@ Reference Control="~/Controls/WebControl1.ascx">
Keep in mind it often takes a few minutes (or sometimes a build) for IntelliSense to pick this up.
