在項目模板中用querystring wp7導航

我在ListBox裏面有一個ListBox.ItemTemplate在wp7應用裏面。我想要的是當用戶在querystring中用titletext點擊標題時導航到somepage。在項目模板中用querystring wp7導航

目前它只是導航到somepage。

<ListBox x:Name="lbname" > 
      <ListBox.ItemTemplate> 
       <DataTemplate> 
        <Grid Background="White"> 
         <Grid.RowDefinitions> 
          <RowDefinition Height="auto" /> 
          <RowDefinition Height="auto" /> 
         </Grid.RowDefinitions> 
         <TextBlock x:Name="tbTitle" Grid.Row="0" Text="{Binding Title}" TextAlignment="Left" FontFamily="Segoe WP" Foreground="#000000" Style="{StaticResource PhoneTextTitle1Style}" > 
          <Custom:Interaction.Triggers> 
           <Custom:EventTrigger EventName="MouseLeftButtonDown"> 
            <ic:NavigateToPageAction TargetPage="/Views/somePage.xaml"/> 
           </Custom:EventTrigger> 
          </Custom:Interaction.Triggers> 
         </TextBlock> 
         <TextBlock x:Name="tbDesc" Grid.Row="1" Margin="11,0,0,0" Text="{Binding Desc}" TextAlignment="Left" FontFamily="Segoe WP" Foreground="#000000" TextWrapping="Wrap" Style="{StaticResource PhoneTextSubtleStyle}" /> 
        </Grid> 
       </DataTemplate> 
      </ListBox.ItemTemplate> 
     </ListBox>

如何做到這一點？
