ContentElement::PreviewQueryContinueDrag Event
Occurs when there is a change in the keyboard or mouse button state during a drag-and-drop operation.
Assembly: PresentationCore (in PresentationCore.dll)
The PreviewQueryContinueDrag event enables the drag source to declare whether the drag-and-drop operation should be canceled.
This event creates an alias for the DragDrop::PreviewQueryContinueDrag attached event for this class, so that PreviewQueryContinueDrag is part of the class members list when ContentElement is inherited as a base element. Event handlers that are attached to the PreviewQueryContinueDrag event are attached to the underlying DragDrop::PreviewQueryContinueDrag attached event and receive the same event data instance.
