如何引用WPF嵌套ListView中的控件？

Question

My XAML:

<ListView x:Name="lvAlbums" ItemsSource="{Binding XPath=/downloads/Album}" SelectionMode="Multiple">
        <ListView.ItemTemplate>
            <DataTemplate>
                <StackPanel x:Name="spAlbum">
                    <!-- Displays first level attributes -->
                    <TextBlock x:Name="AlbumName" Text="{Binding XPath=@Name}"/>
                    <TextBlock x:Name="AlbumArtist" Text="{Binding XPath=@Artist}"/>
                    <ListView x:Name="lvTracks" ItemsSource="{Binding XPath=Item}">
                        <ListView.ItemTemplate>
                            <DataTemplate>
                                <StackPanel x:Name="spTrack">
                                    <!-- Displays the second level attributes -->
                                    <TextBlock x:Name="trackName" Text="{Binding XPath=@Name}"/>
                                    <ProgressBar x:Name="pb1" Minimum="0" Maximum="100" Height="5px" Margin="0,0,0,0"/>
                                </StackPanel>
                            </DataTemplate>
                        </ListView.ItemTemplate>
                    </ListView>
                </StackPanel>
            </DataTemplate>
    </ListView.ItemTemplate>
</ListView>

It populates just fine from an xml file. I have an album and listed underneath are the tracks and a progress bar for each track.

I am now looping though the XML to download each track. How do I refer to the progressbar?

(ProgressBar)lvAlbums[curAlbum].lvTracks[curTrack].spTrack["pb1"]

Something like that.

Answer 1

Please see if this works for you :

var innerListView = lvAlbums.ItemTemplate.FindName("lvTracks", lvAlbums) as ListView;
ProgressBar pbar = innerListView.ItemTemplate.FindName("pb1", innerListView ) as ProgressBar;

Answer 2

Instead of trying to reference the progressbar control, I simply bound data to it and updated the data:

<ProgressBar x:Name="pb1" Value="{Binding XPath=@Progress, Mode=TwoWay, UpdateSourceTrigger=PropertyChanged}" Minimum="0" Maximum="100" Height="5px" Margin="0,0,0,0" Width="145"/>

Works as expected.
