IDragProvider::get_DropEffect method (uiautomationcore.h)

Retrieves a localized string that indicates what happens when this element is dropped as part of a drag-drop operation.

This property is read-only.


HRESULT get_DropEffect(
  BSTR *pRetVal



Return value



In the source-only style of UI Automation drag-and-drop, no elements implement the DropTarget pattern. To find out what effect dropping the dragged element will have, a client can query the DropEffect property of the dragged element. This property can be a short string such as "move", or a longer one, such as "insert into Main group". The string is always localized.

If this property changes, the provider must notify clients by calling UiaRaiseAutomationPropertyChangedEvent and specifying a property identifier of UIA_DragIsGrabbedPropertyId or UIA_DragDropEffectPropertyId.
