WPF globally styling a TextBlock inside a DataGrid

Question

I am encountering a very weird issue. I am trying to apply global styling to several controls within a DataGrid. Most of them work exactly how I would expect them t

Answer 1

So with a bit more digging and a little luck, I discovered that WPF does not apply implicit styles inside templates unless the TargetType derives from Control. Since TextBlock doesn't derive from Control, its style is not applied. So you either have to manually apply the style to every non-Control or define the implicit style inside the template.

The following MSDN blog post explains it in pretty good detail.
