New Post: DoubleUpDown.IsEditable gone?

The "AllowSpin" property allow you to control if the user can "spin" the values, with the "spin buttons", the keyboard arrows or mouse wheel.
The "ShowButtonSpinner" allow you to show or hide the "spin buttons".
The "MouseWheelActiveTrigger" property allow you to control if and when the mouse wheel can "spin" the buttons. (only when AllowSpin is true. Of course)
