I just glimpsed over your tutorial... I think it's exactly what I was looking
for!! and it's a great tutorial, very concise and to the point. Thanks.
I can put together dataReapeter with nested databinding, no problems. Now I
need to figure out how to retrieve all the data entered into the repeater's
controls. I think I have some ideas on how do to that, pobably looping
through ItemTemplates and .FindControls for what I need, right? I have a
feeling I'll be posting again.
