title: WP7 ListPicker scrolling issue
body: <p>I have created the following:</p>
  
  <p>
  
  <pre><code>    &lt;!--Pivot Control--&gt;
     &lt; controls:Pivot Title="name"
  
          &lt;!--Pivot item one--&gt;
         &lt; controls:PivotItem Header="h1"&gt;
              &lt;Grid&gt;
                  &lt;Image Height="140" HorizontalAlignment="Left" Margin="24,21,0,0" Name="image1" Stretch="Fill" VerticalAlignment="Top" Width="200" /&gt;
                 &lt;TextBlock Height="146" HorizontalAlignment="Left" Margin="246,21,0,0" Name="textBlock1" Text="TextBlock" VerticalAlignment="Top" Width="194" /&gt;
                  &lt;StackPanel Margin="10,200,0,0"&gt;
                      &lt;toolkit:ListPicker Header="header1" HorizontalAlignment="Left" Name="ListPicker1" VerticalAlignment="Top" Width="429" /&gt;
                      &lt;toolkit:ListPicker Header="header2" HorizontalAlignment="Left" Name="ListPicker2" VerticalAlignment="Top" Width="429" CacheMode="BitmapCache" /&gt;
                      &lt;toolkit:ListPicker Header="header3" HorizontalAlignment="Left" Name="ListPicker3" VerticalAlignment="Top" Width="429" CacheMode="BitmapCache" /&gt;
                      &lt;/StackPanel&gt;
              &lt;Grid&gt;
          &lt;controls:PivotItem&gt;
  
          &lt;!--Pivot item two--&gt;
          &lt;controls:PivotItem Header="h2"&gt;
              &lt;Grid/&gt;
          &lt;controls:PivotItem&gt;
          &lt;!--Pivot item three--&gt;
          &lt;controls:PivotItem Header="h3"&gt;
             &lt; Grid/&gt;
          &lt;/controls:PivotItem&gt;
      &lt;/controls:Pivot&gt;
  &lt;/Grid&gt;

  <p>the third lisppicker ListPicker3 has 5 items I can only see the first two items and the remaining 3 items are invisble because they are below in the page.  The prob is that I cannot scroll down to see them.</p>
  
  <p>Could someone tell me if there is a way to scroll down the page to see the value of the expanded ListPicker3 or suggest me a method to resolve this.  </p>
  
  <p>Thanks</p>
