问题 I'm trying to display data in a ListView with WPF and C#, and I'm confused by the different examples and methods I have seen. I'm looking for a fully working example similar to my program, or a list of pre-requisites to make it work. I'll be happy if I manage to display just 1 row of data from my collection.
