Accessing IsVisible property of a XAML element's parent in code-behind

if (span.Text == "Specific String")
{
    var spanAncestor = span.Parent.Parent;
    spanAncestor.IsVisible = false; // Throws error. Read below.
}

The error I get is:

Error CS1061 ‘Element’ does not contain a definition for ‘IsVisible’
and no accessible extension method ‘IsVisible’ accepting a first
argument of type ‘Element’ could be found (are you missing a using
directive or an assembly reference?)

The span has as a parent a FormattedString, which has as a parent a Label.

Is there a way to set IsVisible property for the ancestor element?

>Solution :

Parent is of type Element, which does not have an IsVisible property. You need to cast it first

if (parent is VisibleElement)
{
  ((VisibleElement)parent).IsVisible = false;
}
