If you use a BitmapLayer or similar, redrawing only parts of the view might result in visualization of certain object being clipped. By setting this property large enough, you can make sure that close-by objects are included in partial updates, so that texts and other visualization are included in the partial update as well.

Selection of objects, both by the built-in tools and programmatically using the View.WhatsIn or View.WhatsAt methods, is implemented using local updates around the selection point or rectangle. Only features returned in these updates are then processed further, to see if their visualization intersects the selection area. Without this property, features that are close by, but not inside, the selection area would not be found, even if their visualization would intersect the selection area.
