Control.OnTemplateChanged Method
.NET Framework 4.6 and 4.5
Called whenever the control's template changes.
Namespace: System.Windows.Controls
Assembly: PresentationFramework (in PresentationFramework.dll)
protected virtual void OnTemplateChanged( ControlTemplate oldTemplate, ControlTemplate newTemplate )
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:
The template is changed by a SetValue method call, a style trigger, or some other means.
The property value changes; the property-changed callback is called.
The old visual tree is removed.
An internal method is called which eventually calls the OnTemplateChanged method.
Later, during a measure, OnApplyTemplate is called and a new visual tree is attached.
