Property Value

Type: System.Int32
The ancestor level. Use 1 to indicate the one nearest to the binding target element.

If the Mode property is not set explicitly, setting the AncestorType or the AncestorLevel property will implicitly lock the Mode property value to FindAncestor.

The following returns the second ItemsControl encountered on the upward path starting at the target element of the binding.

Binding myBinding = new Binding();
// Returns the second ItemsControl encountered on the upward path 
// starting at the target element of the binding
myBinding.RelativeSource = new RelativeSource(
    RelativeSourceMode.FindAncestor, typeof(ItemsControl), 2);
