Control.OnTemplateChanged(ControlTemplate, ControlTemplate) Method

Definition

Namespace:

System.Windows.Controls

Assembly:

PresentationFramework.dll

Called whenever the control's template changes.

C#

protected virtual void OnTemplateChanged(System.Windows.Controls.ControlTemplate oldTemplate, System.Windows.Controls.ControlTemplate newTemplate);

Parameters

oldTemplate

ControlTemplate

The old template.

newTemplate

ControlTemplate

The new template.

Remarks

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.
