public event EventHandler<RowEditStartedEventArgs> RowEditStarted
Public Event RowEditStarted As EventHandler(Of RowEditStartedEventArgs)
The RowEditStarted event's data class is RowEditStartedEventArgs. The following properties provide information specific to this event:
| Property | Description |
|---|---|
| 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. |
| 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. |
| Row | Gets the processed row. Inherited from RowEventArgs. |
| RowHandle | Gets the processed row’s handle. Inherited from RowEventArgs. |
| Source | Gets or sets a reference to the object that raised the event. Inherited from RoutedEventArgs. |
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. |
Handle this event to specify custom logic that occurs when a user edits a row. If you want to maintain a clean MVVM pattern and process the edit operation in a View Model, create a command and bind it to the RowEditStartedCommand property.
The following example uses the RowEditStarted and RowEditFinished events to pause data updates in the Edit Form:
