You cannot use methods in XAML.

Parameters

oldParent

A value of type DependencyObject that represents the previous parent of the Visual object. If the Visual object did not have a previous parent, the value of the parameter is a null reference (Nothing in Visual Basic).

A class that derives from Visual can choose to override this method.

The following example defines an overridden implementation of OnVisualParentChanged.

public class MyVisual : UIElement
{
    // Class member definitions
    // ...

    protected override void OnVisualParentChanged(DependencyObject oldParent)
    {
        // Perform actions based on OnVisualParentChanged event.
        // ...

        // Call base class to perform standard event handling.
        base.OnVisualParentChanged(oldParent);
    }
}
