Namespace:  System.Workflow.ComponentModel.Design
Assembly:  System.Workflow.ComponentModel (in System.Workflow.ComponentModel.dll)

public class ActivityDragEventArgs : DragEventArgs

The ActivityDragEventArgs type exposes the following members.

Public propertyActivitiesGets a collection of activities upon which a drag-and-drop operation is performed.
Public propertyAllowedEffectGets which drag-and-drop operations are allowed by the originator (or source) of the drag event. (Inherited from DragEventArgs.)
Public propertyDataGets the IDataObject that contains the data associated with this event. (Inherited from DragEventArgs.)
Public propertyDragImageSnapPointGets or sets the location where the activities are to be dropped on the workflow design surface.
Public propertyDragInitiationPointGets the Point on the workflow design surface where a drag operation began.
Public propertyEffectGets or sets the target drop effect in a drag-and-drop operation. (Inherited from DragEventArgs.)
Public propertyKeyStateGets the current state of the SHIFT, CTRL, and ALT keys, as well as the state of the mouse buttons. (Inherited from DragEventArgs.)
Public propertyXGets the x-coordinate of the mouse pointer, in screen coordinates. (Inherited from DragEventArgs.)
Public propertyYGets the y-coordinate of the mouse pointer, in screen coordinates. (Inherited from DragEventArgs.)

Public methodEquals(Object)Determines whether the specified Object is equal to the current Object. (Inherited from Object.)
Protected methodFinalizeAllows an object to try to free resources and perform other cleanup operations before it is reclaimed by garbage collection. (Inherited from Object.)
Public methodGetHashCodeServes as a hash function for a particular type. (Inherited from Object.)
Public methodGetTypeGets the Type of the current instance. (Inherited from Object.)
Protected methodMemberwiseCloneCreates a shallow copy of the current Object. (Inherited from Object.)
Public methodToStringReturns a string that represents the current object. (Inherited from Object.)

These event arguments are passed to ActivityDesigner classes when a drag-and-drop operation is in progress on the workflow design surface. ActivityDesigner classes can access the information contained in the ActivityDragEventArgs class to influence the behavior of the operation.
