Error message

SR.Format(SR.NoPresentationContextForGivenElement, AnnotatedElement)

What it means

MarkedHighlightComponent.RegisterAnchor throws InvalidOperationException(SR.NoPresentationContextForGivenElement) when AdornerLayer.GetAdornerLayer(AnnotatedElement) returns null, i.e. the annotated element is not in a visual tree that can host an adorner layer (it must be a UIElement with a presented parent such as an AdornerDecorator). The component then cannot host its markers.

Solutions

  1. Delay annotation attachment until the annotated element is loaded (handle Loaded event / IsLoaded check).
  2. Ensure the host window contains an AdornerDecorator (Window and most templates include one; custom hosts may need it explicitly).
  3. Verify AnnotatedElement is a UIElement in a live visual tree before calling AddAttachedAnnotation.

Example fix

// before
annotationService.Enable(element); // element not yet in visual tree
// after
if (AdornerLayer.GetAdornerLayer(element) != null)
    annotationService.Enable(element);
else
    element.Loaded += (s, e) => annotationService.Enable(element);
Defensive patterns

Strategy: validation

Validate before calling

if (element is not UIElement ui || AdornerLayer.GetAdornerLayer(ui) == null) return; // not presentable yet

Type guard

static bool HasPresentationContext(object element) => element is UIElement ue && AdornerLayer.GetAdornerLayer(ue) != null;

Try / catch

try { component.AddAttachedAnnotation(a); } catch (InvalidOperationException) { element.Loaded += (s, e) => RetryAttach(a); }

Prevention

When it happens

Trigger: Annotating a control before it is added to the visual tree; annotating an element inside a container without an adorner layer; calling RegisterAnchor (via AddAttachedAnnotation) while the document/viewer is detached or during teardown.

Common situations: Enabling AnnotationService in a window/page constructor before the visual tree is loaded; annotating content in a popup/window that was closed; template parts not yet applied when annotation code runs.
