LabelFormat does not work

Question

I'm trying to apply a string format using the LabelFormat property but no value seems to be valid. There is no example documentation for it as the documentation shows FormatString which no longer exists.

If I enter LabelFormat="{0} days" it shows a syntax error in the editor. If I enter LabelFormat=" {0} days", this is accepted but it fails to build as it says there's no closing tag for it. If I enter LabelFormat="'{0} days'", this works but I get the text encapsulated with single quotes

How I am supposed to prefix the value with text?
