Called when the control's template is applied. In simple terms, this means the method is called just before the control is displayed.
protected override void OnApplyTemplate(TemplateAppliedEventArgs e)
Parameter | Type | Description |
---|---|---|
e | TemplateAppliedEventArgs | The event args. |
OnAttachedToVisualTree(VisualTreeAttachmentEventArgs)
Called when the control is added to a rooted visual tree.
protected override void OnAttachedToVisualTree(VisualTreeAttachmentEventArgs e)
Parameter | Type | Description |
---|---|---|
e | VisualTreeAttachmentEventArgs | The event args. |
OnDetachedFromVisualTree(VisualTreeAttachmentEventArgs)
Called when the control is removed from a rooted visual tree.
protected override void OnDetachedFromVisualTree(VisualTreeAttachmentEventArgs e)
Parameter | Type | Description |
---|---|---|
e | VisualTreeAttachmentEventArgs | The event args. |
OnLoaded(RoutedEventArgs)
