ASP.NET content placeholder in UserControl

I want to be able to do something like this:

<uc:MyUC>
    <CustomContent>
        <span id="name">johnny the assasin</span>
    </CustomContent>
</uc:MyUC>

and having that control able to render

hello <b><span id="name">johnny the assasin</span></b>

but I can't seem to find a way to expose a property that lets me write any markup I want j开发者_高级运维ust like as if I had a content place holder on my user control

Is something like this even possible?

I think you need to define a property of type ITemplate in your control. E.g.

[PersistenceMode(PersistenceMode.InnerProperty)]
public ITemplate CustomContent { get; set; }

and then you could use it in markup like:

<uc:MyUC>
    <CustomContent>
        <span id="name">johnny the assasin</span>
    </CustomContent>
</uc:MyUC> 

More could be found here: How to: Create Templated ASP.NET User Controls

If you set the [ParseChildren(false)] attribute on an asp.net usercontrol, then it will not treat the html tags as control properties.

So in your class definition,

[ParseChildren(false)]
public class MyUC : System.Web.UI.UserControl
{

}

Of course, if you want to have your user control actually have properties, and a property that is rendered 'as is', you may have to create your main user control, and then have the CustomContent property be another usercontrol that just renders the content.
