Listbox datatemplate not working

I know i have made some silly mistake. But won't able to solve.
This is the xaml code:
<Border BorderBrush="Red" BorderThickness="3" Grid.Column="0" Grid.Row="0">
<toolKit:ListBoxDragDropTarget AllowDrop="True" >
<ListBox Height="85" Width="120">
<ListBox.ItemTemplate>
<DataTemplate>
<TextBlock Text="12233"
Foreground="AliceBlue"/>
</DataTemplate>
</ListBox.ItemTemplate>
</ListBox>
</toolKit:ListBoxDragDropTarget>
</Border>
And the screen shot is :
