Hi, Steve. I'm glad that helped a bit. :)

>However, for some reason it won't work with a ComboBox:

but with a ComboBox, that's not "simple binding" anymore, therefore, I don't think you can bind to an integer property. Not sure, but I think with controls like ComboBoxes, ListBoxes, DataGrids, you can only bind data using the DataSource property...

Anyway, I'm also messing around with databinding, so there's not much really clear in my mind about it at this point... <s>
