将 html 标记传递给 ASP.NET 用户控件 [英] Passing html markup into an ASP.NET User Control
问题描述
在下面的例子中，
<uc1:MyUserControl><p>这是html</p></uc1:MyUserControl>如何在 MyUserControl 中将 "<p>this is html</p>" 作为字符串访问，以便将其注入响应中?
我不是在谈论传递像 <uc1:MyUserControl myparameter="<p>this is html</p>" 这样的字符串参数/>，但是如何在开始和结束标记之间或通过诸如 <MessageTemplate> 标记等其他机制访问真正的多行智能 HTML 标记.p>
适用于 ASP.NET MVC 3 的解决方案的奖励积分！
感谢 StriplingWarrior 和 此链接 作为缺失的拼图，魔法被创造了:
所以，在任何情况下:
<%@注册src="../../Shared/Ribbon.ascx" tagname="Ribbon" tagprefix="uc1" %>...<uc1:Ribbon ID="Ribbon" runat="server"><内容>你好世界！我是<b>纯html</b>被传递到用户控件中！</内容></uc1:功能区>在 Ribbon.ascx 中:
<%@ Control Language="C#" CodeBehind="Ribbon.ascx.cs" Inherits="NunYourBeezwax.Views.Shared.Ribbon" %><桌子><tr><td>我是围绕动态内容的可重复使用的东西</td><td><%= this.Content %></td><td>而我也是这样的</td></tr></表>最后，在 Ribbon.ascx.cs 中(需要在 MVC 中手动添加)
使用 System.Web.Mvc;使用 System.Web.UI；命名空间 NunYourBeezwax.Views.Shared{[ParseChildren(真，内容")]公共类功能区:ViewUserControl{[PersistenceMode(PersistenceMode.EncodedInnerDefaultProperty)]公共字符串内容{获取；放;}}}将呈现为:
<tr><td>我是围绕动态内容的可重复使用的东西</td><td>世界你好！我是<p>纯html<p>被传递到 UserControl！</td><td>而我也是这样的</td></tr></表> 解决方案 在典型的 WebForms 控件中，HTML 会自动放入 MyUserControl 的 Controls 集合中的 Literal 控件中.具有模板属性的控件的工作方式略有不同，但您仍然可以通过您正在使用其名称的属性(例如 MessageTemplate)以类似的方式访问它.
MVC 的工作方式完全不同，我不知道是否有一种方法可以满足您的要求.如果对您不起作用，您可能需要考虑使用 javascript 来分析实际在客户端呈现的内容.
In the following example,
<uc1:MyUserControl>
<p>this is html</p>
</uc1:MyUserControl>
How do I access "<p>this is html</p>" as a string within MyUserControl so that I might inject it into the response?
I'm not talking about passing in a string parameter like <uc1:MyUserControl myparameter="<p>this is html</p>" />, but how do I access true multi-lined intellisensed HTML markup either between the opening and closing tags or by some other mechanism such as a <MessageTemplate> tag.
Bonus points for a solution that works in ASP.NET MVC 3!
EDIT:
Thanks to StriplingWarrior and this link as the missing puzzle piece, magic was made:
So, in any view:
<%@ Register src="../../Shared/Ribbon.ascx" tagname="Ribbon" tagprefix="uc1" %>
...
<uc1:Ribbon ID="Ribbon" runat="server">
<Content>
Hello world! I am <b>pure html</b> being passed into a UserControl!
</Content>
</uc1:Ribbon>
In Ribbon.ascx:
<%@ Control Language="C#" CodeBehind="Ribbon.ascx.cs" Inherits="NunYourBeezwax.Views.Shared.Ribbon" %>
<table>
<tr>
<td>I am reusable stuff that wraps around dynamic content</td>
<td><%= this.Content %></td>
<td>And I am stuff too</td>
</tr>
</table>
And finally, in Ribbon.ascx.cs (Need to manually add in MVC)
using System.Web.Mvc;
using System.Web.UI;
namespace NunYourBeezwax.Views.Shared
{
[ParseChildren(true, "Content")]
public class Ribbon : ViewUserControl
{
[PersistenceMode(PersistenceMode.EncodedInnerDefaultProperty)]
public string Content { get; set; }
}
}
Will Render as:
<table>
<tr>
<td>I am reusable stuff that wraps around dynamic content</td>
<td>Hello world! I am <p>pure html<p> being passed into a UserControl!</td>
<td>And I am stuff too</td>
</tr>
</table>
解决方案 In typical WebForms controls, the HTML will be automatically put into a Literal control in MyUserControl's Controls collection. Controls with template properties work a little differently, but you may still be able to access this in a similar way through the property whose name you're using (e.g. MessageTemplate).
MVC works totally differently, and I don't know if there's a way to do what you're asking there. You may want to consider using javascript to analyze what actually gets rendered client-side if it doesn't work for you.
