title: Add items to a ListBox and bind them to an item in another Listbox
body: <p>My apologies in advance, I might have difficulty in making myself clear. I have searched, but the discussions were far to complicated for me to follow, and I just started dwelling in C#.</p>
  
  <p>Project: C# WindowsForm / .NET 4.5 / Visual Studio 2012</p>
  
  <p><strong>Challenge</strong>:
  I want to add items from a listbox to another listbox (I can do it easily with Lists and foreach loops), and make the end listbox show specific item depending on selections made in listbox2.</p>
  
  <p><strong>Explanation</strong>:
  The selected items are to incorporate a group that I create in yet another listbox, so that if I select a handful of items in listbox1, I send them to listbox3, but they only should appear when I select a specific item in listbox2.</p>
  
  <p>Imagine selecting games from a list, adding it to the "Nintendo" group in a new list, so they don't get mixed with the Sega ones when Sega is selected in listbox2.</p>
  
  <p>I can add values in all listboxes, copy the ones I want from 1 to 3, but I am at a loss on how to make the selection respect the selection on 2.</p>
  
  <p>I've read about databinding and etc, but the examples gives were too complicated (and maybe a bit of language barrier was present), is there a resource that can provide the simplest solution to a really small project?</p>
  
  <p>Care to enlighten a fool using layman terms, please?</p>
  
  <p>Thanks</p>
  
  <p>EDIT:
  Nice of you (whoever you were) to downvote my question. Fair enough. You could at least tell me what the problem was, or where the question was answered so I could resolve my problem. Wouldn't that be nice? I am a starter in C#, so it's only natural that the first question may seem ridiculous/lazy...</p>
