Nearly a month and a half ago, I'd posted about writing up a Repeater
control that allows for a <NoneTemplate> that would be used when its
datasource is empty. I had a couple of people ask me for the source, and
I'd meant to release it, but kept forgetting as things kept coming up (work,
holidays, DevConnections). So finally today I sat down, did a quick
build, wrote a short sample, and zipped it up.
I've coined it RepeaterPlusNone. We've put
it to use quite well in Community Server and it works great. So...
