c# - Create WPF Watermark in Pure XAML

Question

This is for a TextBox control on a login screen, where the TextBox contains the username. I want the TextBox to perform in the following way:

• When the content is empty the content should be set to "Username".

• When the TextBox is clicked I want the content to be set to "" i.e; nothing (unless the content has already been edited by the user).

This is a pretty standard feature nowadays, something like this wordpress login (at the top of page). coudn't think of a better example than this I'm afraid :)

So, anyway, I've already done this using a ViewModel and it works well, but I'd like to know if this can be done purely from the XAML end. No business logic is concerned so I think it would be better to do it without the VM.
