Question

I have a ListBox whose ItemsSource is databound to a list of ints.
I’d like to bold bold a few of the items, on the basis of their value.

There are two options that come to (my) mind:

1) Use a DataTrigger that bolds the value if it’s a match.

2) Use a class to wrap the ints and pair each int with a boolean that denotes if the value should be bolded or not.

In any case I’d need a DataTemplate/ItemTemplate, right?
I’ve played around with this but haven’t got it working yet.

Cheers,
Pom

Yes, in either case you’d need a DataTemplate. In fact, the only time you can get away with not using a DataTemplate is if you’re happy with the default format of the text in each ListBoxItem.

BTW, you missed another option:

• Use a converter to determine whether the value falls in the appropriate range.

That said, if you’re doing MVVM, I’d generally recommend your second option.
