Namespace:  System.Windows.Controls

Protected Overridable Sub OnTemplateChanged ( _
	oldTemplate As ControlTemplate, _

)
'Usage

You cannot use methods in XAML.

Parameters

oldTemplate
Type: System.Windows.Controls.ControlTemplate

The old template.

newTemplate
Type: System.Windows.Controls.ControlTemplate

The new template.

The timing for changing the template is as follows:

  1. The template is changed by a SetValue method call, a style trigger, or some other means.

  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 the OnTemplateChanged method.

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