title: Accessing multiple selected items in a ListPicker
body: <p>I came across the new Toolkit for Windows Phone that has the ListPicker control. Now after my searching I wanted to ask you people if I could actually select multiple items in a Listpicker and then use them?</p>
  
  <p>I've completed the adding and selecting multiple items part by using <code>SelectionMode="Multiple"</code></p>
  
  <p>The XAML Code:</p>
  
  <pre><code>&lt;toolkit:ListPicker x:Name="TopStoriesListPicker" Margin="0" Header="Top Stories" Width="422" SelectionMode="Multiple" FullModeHeader="Top Stories" TabNavigation="Local" Style="{StaticResource ListPickerStyle1}"&gt;
                          &lt;sys:String&gt;BBC&lt;/sys:String&gt;
                          &lt;sys:String&gt;CNN&lt;/sys:String&gt;
                          &lt;sys:String&gt;FOX&lt;/sys:String&gt;
                          &lt;sys:String&gt;SKY&lt;/sys:String&gt;
  &lt;/toolkit:ListPicker&gt;
  </code></pre>
  
  <p>Now how can I access these items after they have been multi checked?
  For one item I could have done:</p>
  
  <pre><code>if (TopStoriesListPicker.SelectedItem == CNN)
      do something
  </code></pre>
  
  <p>But now I have multiple items, plus the fact that these are no more proper items but have been defined by <code>sys:String</code>.</p>
