MouseWheelEventArgs::Delta Property
.NET Framework (current version)
Gets a value that indicates the amount that the mouse wheel has changed.
Assembly: PresentationCore (in PresentationCore.dll)
Property Value
Type: System::Int32The amount the wheel has changed. This value is positive if the mouse wheel is rotated in an upward direction (away from the user) or negative if the mouse wheel is rotated in a downward direction (toward the user).
The effective upper and lower ranges of this value potentially come from device implementations or other callers that raised the event, and are therefore not defined.
