Question

I have a list box with an item template defined in XAML like this:

        <ListBox Name="listBoxDisruptions">

            <ListBox.ItemTemplate>
                <DataTemplate>
                    <StackPanel Orientation="Horizontal" Margin="0,0,0,10">
                        <TextBlock Text="{Binding text}" Foreground="Black" FontSize="29">Hello! some item</TextBlock>
                    </StackPanel>
                </DataTemplate>
            </ListBox.ItemTemplate>             

        </ListBox>

Now what i want is to display a line of text in the center of the listbox in case the ItemSource for this listbox is empty.

Does XAML support some kind of no item template, ? something like this:

    <ListBox Name="listBoxDisruptions">

                <ListBox.ItemTemplate>
                    <DataTemplate>
                        <StackPanel Orientation="Horizontal" Margin="0,0,0,10">
                            <TextBlock Text="{Binding text}" Foreground="Black" FontSize="29">Hello! some item</TextBlock>
                        </StackPanel>
                    </DataTemplate>
                </ListBox.ItemTemplate> 

<ListBox.NoItemTemplate>
<TextBlock Text="No Items to display"/>
</ListBox.NoItemTemplate>                   

            </ListBox>

So ?

There might be a XAML way to do it using WPF-like techniques – Listbox Item Template for an empty list

However, in Overflow7 I got bored trying to make these work – so I used a slightly-hacky trick instead of adding an extra TextBlock to the page and then using:

private void PhoneApplicationPage_Loaded(object sender, RoutedEventArgs e) { 
            listBox1.ItemsSource = data; 

            data.CollectionChanged += new System.Collections.Specialized.NotifyCollectionChangedEventHandler(data_CollectionChanged); 

        } 

        void data_CollectionChanged(object sender, System.Collections.Specialized.NotifyCollectionChangedEventArgs e) { 
            if (data.Count == 0) 
                textBlock1.Visibility = Visibility.Visible; 
            else 
                textBlock1.Visibility = Visibility.Collapsed; 
        }
