The old template.


The new template.

Return Value

A template.

The timing for changing the template is as follows:

  1. Somehow the template is changed, for example, by SetValue or a style trigger.

  2. The property value changes; the property changed callback is called.

  3. The old visual tree is removed.

  4. An internal method is called which eventually calls OnTemplateChanged.

  5. Later, during a measure EnsureVisuals is called and a new visual tree is attached.
