Property Value

Type

The type of ancestor. The default value is null.

Exceptions

InvalidOperationException

The RelativeSource is not in the FindAncestor mode.

Examples

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);

Dim myBinding As 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, GetType(ItemsControl), 2)

Remarks

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