Wow Kevin, I can't believe no one replied to this yet.

I have NOT used classes like this for databinding ... as you know, I use DataSets for everything. But, I know you can make use of bindings, like BindingSource and IBindingList ... I just don't have all the particulars of exactly how to do it.

I'd research that if I were you. There is no way that you should have to be clearing and re-adding DataBindings like you're doing. Once you've bound a TextBox, the binding position should dictate which item you'll display in that TextBox, without you having to fiddle around with it. Again, I'm sorry I don't have concrete examples, but it shouldn't be too hard to do.
