I get the following answer form AI assistant Claude:
In UWP, you can calculate the intersection of a UI element with its parent like this: Get the Rect of the child element relative to the parent:
Rect childRect = childElement.TransformToVisual(parentElement) Rect childRect = childElement.TransformToVisual(parentElement).TransformBounds(new Rect(0, 0, childElement.ActualWidth, childElement.ActualHeight));
Get the Rect of the parent element:
Rect parentRect = new Rect(0, 0, parentElement.ActualWidth, parentElement.ActualHeight);
Use Rect.Intersect to get the intersection:
Rect intersection = Rect.Intersect(childRect, parentRect);
The intersection Rect will have a non-zero width and height if the elements intersect. You can check it like this:
if (intersection.Width > 0 && intersection.Height > 0) { Elements intersect! } else { No intersection }
I am not sure it's the most conside and elegant way. Is there any builtin method to achieve same purpose?
