Occurs when the user begins dragging an item.
Assembly: System.Windows.Forms (in System.Windows.Forms.dll)
The event occurs when the user begins dragging an item. Typically the event handler for the event performs the task of dragging by calling the Control::DoDragDrop method. You can use this event to perform the tasks necessary to drag items into and out of your application's ListView control.
For more information about handling events, see Consuming Events.
The following code example demonstrates the use of this member. In the example, an event handler reports on the occurrence of the event. This report helps you to learn when the event occurs and can assist you in debugging. To report on multiple events or on events that occur frequently, consider replacing MessageBox::Show with Console::WriteLine or appending the message to a multiline TextBox.
To run the example code, paste it into a project that contains an instance of type ListView named ListView1. Then ensure that the event handler is associated with the event.
