如何在asp.net中将用户控件的引用添加到web.config [英] How do I add reference of user control to web.config in asp.net

问题描述

'我想在网站的代码隐藏中以编程方式创建用户控件的实例*。我发现以编程方式引用用户控件的类的唯一方法是：
 
在web.config中注册控件并将控件放在页面上（工作，但我不想要控制页面，因为我想动态添加它。 
添加<％@    参考   控制  =  Name.aspx >             aspx     page          top。  
   
  理想情况下   我   将   想要    to        任何    aspx     page     reference         control    没有    ha ving     to     put        <％@    参考>    声明            top      < span class =code-attribute>  每个   页。   我   知道   我       注册   控件            web.config     so    我   不要       到   做           每个   页面，    so    < span class =code-attribute>我   想知道   如果       类似   存在    for     references。   我   几乎   某些   我   缺少   某事    about        整个   注册/引用   概念，    so    或许   只是       说明       什么       最佳   方式    to     do    此        in     order。 

解决方案

将包含UserControl的DLL添加到Bin文件夹。您可以像使用添加引用一样使用它。

 <？  xml     version   =  1.0 ？ >  
 
 <  配置 >  
 
 <   system.web  >  
 
 <   pages  >  
 <   controls  >  
 <   add    < span class =code-attribute> tagPrefix   =  scottgu    src   = 〜/ Controls / Header.ascx    tagName   = 标题  /  > ;  
 <   add     tagPrefix   =  scottgu    src   = 〜/ Controls / Footer.ascx    tagName   = 页脚  /  >  
 <   add     tagPrefix   =   ControlVendor    assembly   =  ControlVendorAssembly  /  >  
 <   / controls  < span class =code-keyword>>  
 <   / pages  >  
 
  <   / system.web  >  
 
 <   / configuration  >

'm looking to create an instance of a user control programatically in a codebehind of a web site*. The only ways I've found to reference the class of the user control programatically have been:

Register the control in the web.config and drop the control on the page (works, but I don't want the control on the page as I want to dynamically add it).
Add a <%@ Reference Control="Name.aspx"> to the aspx page at the top.

Ideally I would want to have any aspx page reference the control without having to put the <%@ Reference> declaration at the top of each page. I know I can "Register" controls in the web.config so I don't have to do that on every page, so I'm wondering if something similar exists for references. I'm almost certain I'm missing something about the whole registering/referencing concept, so perhaps just an explanation of what the best way to do this is in order.

解决方案

Add the DLL containing your UserControl to the Bin folder. You will be able to use it as if you had added a reference.

<?xml version="1.0"?>

<configuration>

  <system.web>

    <pages>
      <controls>
        <add tagPrefix="scottgu" src="~/Controls/Header.ascx" tagName="header"/>
        <add tagPrefix="scottgu" src="~/Controls/Footer.ascx" tagName="footer"/>
        <add tagPrefix="ControlVendor" assembly="ControlVendorAssembly"/>
      </controls>
    </pages>

  </system.web>

</configuration>
