How to render html from database with ascx controls

Hi,
I'm creating an website where the template and content is retrieved from the database.
I want for example to add the following code, in the body, at runtime:
<div>
  <h1>
    <CMS:WebuserControl1 ID="control1" runat="server" />
  </h1>
  <p>
    text
  </p>
</div>
What do I need to do to let .NET render the WebuserControl1 after adding the code?
Thx.
