ASP.NET用户控件内部内容 [英] ASP.NET User Control inner content

问题描述

我有接受title属性的用户控件。我也一样，输入内部HTML（ASP也控制）像这样的用户控件标记中：

I have a user control which accepts a title attribute. I would also like that input inner HTML (ASP Controls also) inside of that user control tag like so:

<uc:customPanel title="My panel">
     <h1>Here we can add whatever HTML or ASP controls we would like.</h1>
     <asp:TextBox></asp:TextBox>
</uc:customPanel>

我怎样才能做到这一点？我有title属性正常工作。

How can I achieve this? I have the title attribute working correctly.

感谢。

推荐答案

实现一个可扩展面板，实现作INamingContainer的类：

Implement a class that extends Panel and implements INamingContainer:

public class Container: Panel, INamingContainer
{
}

然后，你CustomPanel需要公开类型的容器的属性和类型的ITemplate的另一个属性：

Then, your CustomPanel needs to expose a property of type Container and another property of type ITemplate:

public Container ContainerContent
{
    get
    {
       EnsureChildControls();
       return content;
    }
}
[TemplateContainer(typeof(Container))]
[TemplateInstance(TemplateInstance.Single)]
public virtual ITemplate Content
{
    get { return templateContent; }
    set { templateContent = value; }
}

然后在方法的CreateChildControls（），补充一点：

if (templateContent != null)
{
    templateContent.InstantiateIn(content);
}

和你会使用这样的：

<uc:customPanel title="My panel"> 
    <Content>    
        <h1>Here we can add whatever HTML or ASP controls we would like.</h1>
        <asp:TextBox></asp:TextBox>
     </Content>
</uc:customPanel>
