{Binding RelativeSource={RelativeSource Self},
Path=Height}
Width="{Binding RelativeSource={RelativeSource Self}, Path=Parent.ActualWidth}"
Height="{Binding RelativeSource={RelativeSource Self}, Path=Parent.ActualHeight}"

is similar to
{TemplateBinding Path=propertyOfControlTemplate}
but standard Binding is preferred
