title: Issue when binding combobox and listbox to List (VB.NET)
body: <p>I'm trying to bind a ComboBox and a ListBox to a List(Of String) in Vb.Net (VS2013), this is for a WinForms application, the thing is that after setting the DataSource property on both the ComboBox and the ListBox, selecting one item on either one of them affects the other control, for example, after the controls have been populated with the information if I select an item from the ListBox, then the same item gets selected in the ComboBox, and this goes the same way for the ComboBox, if I select an item from it, then that item gets also selected in the ListBox, so my question is... how can I bind the combobox and listbox to the same List(Of String) without affecting the behavior on the controls, the purpose is to keep all the controls within that form syncronized based on the contents of the List, I declared the List in a module like this:</p>
  
  <pre><code>Public listaAreas As New List(Of String)
  </code></pre>
  
  <p>then the controls are populated like this on form load:</p>
  
  <pre><code>    cmbArea.DataSource = listaAreas
      lstAreas.DataSource = listaAreas
  </code></pre>
  
  <p>And I run this method whenever I need to update the information:</p>
  
  <pre><code>Private Sub RefreshLists()
      lstAreas.DataSource = Nothing
      lstAreas.DataSource = listaAreas
  
      cmbArea.DataSource = Nothing
      cmbArea.DataSource = listaAreas
  End Sub
  </code></pre>
  
  <p>Please let me know if I'm missing some information, this is my first post but I think it is clear enough so you get the idea of what I'm trying to accomplish here ... =)</p>
  
  <p>Thanks in advance!</p>
