ContentElement.PreviewMouseWheel Event

Definition

Occurs when the user rotates the mouse wheel while the mouse pointer is over this element.

public:
 virtual event System::Windows::Input::MouseWheelEventHandler ^ PreviewMouseWheel;
public event System.Windows.Input.MouseWheelEventHandler PreviewMouseWheel;
member this.PreviewMouseWheel : System.Windows.Input.MouseWheelEventHandler 
Public Custom Event PreviewMouseWheel As MouseWheelEventHandler 

Event Type

Implements

Remarks

Focus or mouse capture take precedence over where the mouse pointer is; therefore, if you receive this event from a focused or captured element, the mouse pointer might actually be over another element.

This event creates an alias for the Mouse.PreviewMouseWheel attached event for this class, so that PreviewMouseMove is part of the class members list when ContentElement is inherited as a base element. Event handlers that are attached to the PreviewMouseMove event are attached to the underlying Mouse.PreviewMouseWheel attached event and receive the same event data instance.
