.NET Windows Forms in a Nutshell

Name

QueryContinueDragEventArgs

Synopsis

This class encapsulates the data for the Control.QueryContinueDrag event.

The Control raises this event periodically throughout a drag-and-drop operation initiated by Control.DoDragDrop().

If you bind to it, you can use this object to set the expected Action, perhaps forcing the operation to Continue or Cancel.

EscapePressed and KeyState provide information as to whether the user pressed the Esc key, and which other modifier keys (CTRL, SHIFT, ALT) were depressed at the time.
