Question

I have a ListBox whose datacontext is an:

ObservableCollection<Item>

Item is a base class, and from it inherits a Potion class, and then from that inherits a HealthPotion class.

So:

Item -> Potion -> HealthPotion

My ListBox template looks something like this:

<DataTemplate>
    <StackPanel Orientation="Vertical" Margin="0,0,0,17">
        <TextBlock Text="{Binding PropertyFromItem}" />
        <TextBlock Text="{Binding PropertyFromPotion}" />
        <TextBlock Text="{Binding PropertyFromHealthPotion}" />
    </StackPanel>
</DataTemplate>

For some reason, the textblock that binds to PropertyFromHealthPotion (grandchild of Item) won’t display data, yet the other two will. Any ideas why?

Thanks in advance.

As discussed in comments:

Are you sure you have healthpotion in there? put a into the DataTemplate to check! Is the property public? if you’re expecting it to change, do you RAISE PropertyChanged correctly? By all means, your code SHOULD work….
