Gets which drag-and-drop operations are allowed by the originator (or source) of the drag event.

Syntax

public DragDropEffects AllowedEffect { get; }

Value

Documentation for this section has not yet been entered.

Remarks

When a control initiates a drag-and-drop operation by calling the Control.DoDragDrop(object, DragDropEffects) method, it specifies the permissible effects of the operation. For example, when you drag a file from a source, if the file is read-only (or from a read-only storage medium such as a CD), the source will indicate that the file can be copied, but not transferred, to the target.

Before attempting to perform an operation on the dragged data, you should examine this property to ensure that the operation is allowed.
