You need to supply a new template, which is way more than just one line.

See the templates here:

As per Microsoft's UG,

There is no way to replace only part of the visual tree of a control; to change the visual tree of a control you must set the Template property of the control to its new and complete ControlTemplate.

You need to describe the entire template of the control. Here is how you can get the full default template of a control : How to Extract Default Control Template In Visual Studio?
