Question

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 just like as if I had a content place holder on my user control

Is something like this even possible?

Answer 1

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>
