Repeated Headers in a Repeater

[Robert Walter]

I was looking for a method to repeat the headers on an ASP.NET
Repeater control. I couldn't find quite what I wanted on the web so I
implemented it myself. I thought it maybe useful for some of you out
there (code is below). It works exactly the same as a normal repeater
except that there is an extra property HeaderRepeatRow s in it.

Note, if you use this generate a table then put the <table> tag
outside the header template otherwise it'll be repeated each time the
header is.

A similar method can probably be used to do the same for a datagrid
but it's made a bit more difficult as you have the header
automatically being generated.
