Databinding templated controls exclusively from the code behind

Implementing databinding from the ASPX/ASCX file is very
straightforward:
<asp:XmlDataSource id="XmlDs1" DataFile="[some RSS feed]">...</>
<asp:Repeater>
<HeaderTemplate><%#XPath("title")%></>
</>

However, what if you wanted to do this ONLY from the code behind? For
example, if I didn't have a repeater on an ASPX page or anything... it
would be added dynamically. How you do you do something like this:

// bind XmlDataSource to a repeater
// create & add an ASP.NET HyperLink control to the HeaderTemplate of a
repeater that was added to the page.
someLink.NavigationUrl = "#XPath("title") ; // I know this won't
work, just trying to convey the concept

Is this even possible? I'm fairly certain it is, just keep hitting a
dead end and can't find any articles out there that demonstrate it.

Thanks again, that article was spot on. However, I've got a question about binding with an XmlDataSource and using the XPath method.

Say, in markup, I create an XmlDataSource and set the DataFile to an RSS feed with no XPath defined. Then I associate it to a Repeater, and inside the Repeater, I have a <%# XPath("title") %> to fetch the title of the feed.

I'm having one heck of a time getting this to work in a 100% pure code behind model. I've tried numerous permutations with no success. Even obtaining a reference to the DataItem within my event handler returns an object that's not even listed in the SDK. ideas?
 
Unfortunately, my experience with xml-related matters is rather limited.You
will get better response if you re-post it in a separate thread.

xxxTemplate properties can be created in two ways. You can either load
them from external files

myRepeater.HeaderTemplate.LoadTemplate(fileName)

or you can use custom Template classes:
