DragPattern/DragDropPattern elements requires valid DropEffect

Text

Elements that support Drag/Drop should have a valid 'DropEffect' set

Type

Error

Description

The element supports either IUIAutomationDragPattern or IUIAutomationDropTargetPattern, but does not have a valid DropEffect property set.

This issue causes problems for people who rely on a screen-reader. The user will not be able to tell what effect this object has when dragging.

Possible causes

  • The element, or its parent, has not created the DropEffect or DropEffects an incorrectly assigned name or label.
  • A developer is not aware that screen readers read DropEffect(s).
