|Xbox 360 Specific Information|
|The value of this property is always 0.|
Assembly: Microsoft.Xna.Framework (in microsoft.xna.framework.dll)
Unlike standard Windows and WinForms mouse messages, which report a relative value for the scroll wheel, XNA reports the total scroll wheel value accumulated over the length of a game's execution. To process a wheel movement, you must compare the previous frame's wheel value to the current wheel value.
