Public Event RowDoubleClick As RowDoubleClickEventHandler
The RowDoubleClick event's data class is RowDoubleClickEventArgs. The following properties provide information specific to this event:
| Property | Description |
|---|---|
| ChangedButton | Gets a mouse button that has been pressed twice. |
| 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. |
| HitInfo | Gets or sets the information on a view element located under the mouse pointer. |
| 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 the View that raised the event. |
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. |
The HitInfo property returns information about a view element that a user double-clicks. Refer to the following topic for more information: Hit Information.
If you want to maintain a clean MVVM pattern and process the node double-click operation in a View Model, create a command and bind it to the RowDoubleClickCommand property.
