How do I create a custom webcontrol that can have xml inside it's tag?
I mean a control like the repeater control, where I can specify special tags
that define the header body and footer of the control.
I'm thinking of something like:
<uc1:CustomControl ID="Control1" runat="server">
<Header>Some text and perhaps other controls</Header>
<Body>Some more text</Body>
<Footer>Even more text</Footer>
</uc1:CustomControl>

Is there a technical term for this? I haven't been able to find information
about this.

Kind Regards,

ParseChildrenAttribute(false) should get you started. ASP.Net by default
tries to deserialize child markup to the owning object, but if you disable
child parsing, you can control it yourself.

Thanks,
I've found that I need to create a custom Control Builder for my control,
since creating a custom control builder runs at compiletime while overriding
..AddSubParsedObject runs at runtime. The samples I've found online aren't
very informative, I haven't found examples that explain how I can create a
Control Builder that finds custom tags inside its tags and handles them like
the repeater control.
Any help on creating custom control builders is appreciated.
I'll keep investigating.

some of the links I've looked at:

I've tried to get the sample:
http://samples.gotdotnet.com/quickstart/util/srcview.aspx?path=/quickstart/aspplus/samples/webforms/ctrlauth/templates/Repeater1.src&file=CS\Repeater1.aspx&font=3
to work but it keeps saying that The TemplateControlSamples:Repeater1 tag in
the aspx page cant have content between it's opening and closing tags.
What am I doing wrong?
