Question

I have a collection
private ObservableCollection<ImageData> imageDataList = new ObservableCollection<ImageData>(); where ImageData is a custom object. It has an attribute called fileName a string that stores full path of an image file. In my XAML code, I have a listbox with datatemplate as the following.

<ListBox Name="listBox_ImageList" Grid.ColumnSpan="3" Grid.Row="2" SelectionChanged="listBox_ImageList_SelectionChanged">
        <ListBox.ItemsPanel>
            <ItemsPanelTemplate>
                <VirtualizingStackPanel Orientation="Horizontal" />
            </ItemsPanelTemplate>
        </ListBox.ItemsPanel>

        <ListBox.ItemTemplate>
            <DataTemplate>
                <Image Source="{Binding fileName}" Height="{Binding RelativeSource={RelativeSource FindAncestor, AncestorType=ListBox, AncestorLevel=1}, Path=ActualHeight}"/>
            </DataTemplate>
        </ListBox.ItemTemplate>
    </ListBox>

After populating ImagaData objects into imageDataList, I set this.listBox_ImageList.ItemsSource = imageDataList;

However, when I run it, I don’t see any images. Can you please tell me how to databind properly to a string member of an object to WPF image source?
