Occurs when a user presses the keyboard or mouse buttons during a drag-and-drop operation. The event allows you to cancel this operation depending on the key/button states.
public event EventHandler<ContinueRecordDragEventArgs> ContinueRecordDrag
Public Event ContinueRecordDrag As EventHandler(Of ContinueRecordDragEventArgs)
The ContinueRecordDrag event's data class is ContinueRecordDragEventArgs. The following properties provide information specific to this event:
|Action||Gets or sets the status of a drag-and-drop operation.|
|Data||Gets or sets a data object that contains data associated with the DataViewBase.ContinueRecordDrag event.|
|EscapePressed||Gets whether the user pressed the ESC key.|
|Handled||Gets or sets a value that indicates the present state of the event handling for a routed event as it travels the route. Inherited from RoutedEventArgs.|
|KeyStates||Gets a flag enumeration indicating the current state of the SHIFT, CTRL, and ALT keys, as well as the state of the mouse buttons.|
|OriginalSource||Gets the original reporting source as determined by pure hit testing, before any possible Source adjustment by a parent class. Inherited from RoutedEventArgs.|
|RoutedEvent||Gets or sets the RoutedEvent associated with this RoutedEventArgs instance. Inherited from RoutedEventArgs.|
|Source||Gets or sets a reference to the object that raised the event. Inherited from RoutedEventArgs.|
The event data class exposes the following methods:
|InvokeEventHandler(Delegate, Object)||When overridden in a derived class, provides a way to invoke event handlers in a type-specific way, which can increase efficiency over the base implementation. Inherited from RoutedEventArgs.|
|OnSetSource(Object)||When overridden in a derived class, provides a notification callback entry point whenever the value of the Source property of an instance changes. Inherited from RoutedEventArgs.|
The TreeViewControl raises the ContinueRecordDrag event continuously while a user drags a record. You can handle this event to determine what action ends the drag-and-drop operation based on the state of the ESC, SHIFT, CTRL, and ALT keys, and the state of the mouse buttons.
The default handler for this event cancels the drag-and-drop operation if a user presses the ESC key, and drops the data if a user releases the mouse button.
