title: Move Up, Move Down Buttons for ListBoxes in Visual Studio
body: <p>I am trying to make a Move Up Button, and a Move Down Button, to move a selected item in a ListBox in Microsoft Visual Studio 2012. I have seen other examples in WDF, jquery, winforms, and some other forms but I haven't seen examples from Microsoft Visual Studio yet. </p>
  
  <p>I have tried something like this:</p>
  
  <pre><code>        listBox1.AddItem(listBox1.Text, listBox1.ListIndex - 1);
  </code></pre>
  
  <p>But Microsoft Visual Studio didn't have an "AddItem" property in their ListBoxes. </p>
  
  <p>For more information, I have two listboxes that I want to make my Move up and down Buttons work with; the SelectedPlayersListBox, and the AvailablePlayersListBox. Will someone be kind enough to give me examples of a Move Up and Down button in Microsoft Visual Studio? Thank you.</p>
