Event Data

The TaskMoved event's data class is TaskMovedEventArgs. The following properties provide information specific to this event:

Property Description
Cancel Gets or sets whether the applied changes must be canceled.
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.
Node Gets the currently edited task.
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.
StartDate Gets or sets the currently edited task start date.

The event data class exposes the following methods:

Method Description
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.

Remarks

Use the TaskMovedEventArgs.Node property to get the task whose start date has been edited.

You can change the edited start date using the TaskMovedEventArgs.StartDate property.

You can undo the applied changes by setting the TaskMovedEventArgs.Cancel property to true.
