Why LongListSelector ItemTemplate Doesn't Show Anything? - xaml

Question

I need a pivot page that in every pivot page there is a longlistselector to list the data...
this is the code that i write when i create a simple pivot page
<phone:PivotItem Header="all">
<phone:LongListSelector Name="AllNotes"
Background="Black"
Margin="0,0,0,0">
<phone:LongListSelector.ItemTemplate>
<DataTemplate>
<StackPanel Background="White"
Margin="0,17,0,0">
<TextBlock Text="aaaa">
</TextBlock>
</StackPanel>
</DataTemplate>
</phone:LongListSelector.ItemTemplate>
</phone:LongListSelector>
</phone:PivotItem>
but there isn't anything in the pivot item
i mean by defining a data template and then a stackpanel, there is nothing shown in the pivot item
can you help me ti figure out whats happening exactly?

I finally solve this problem in the way that I don't believe it!
The answer is that we have to start writing the application in the base of Pivot Application !!!
That I don't believe this in the first place!
But Thank You Anyway :)
