WPF Spin Controls
WPF Elements provides two "spin" controls which provide "up-down" functionality for numeric values.
The Spin control provides an "up-down button" user interface for modifying numeric values. You can set maximum and minimum values.
WPF Elements also provides a SpinDecorator control which automatically attaches a Spin control to another control such as a NumericTextBox, providing a user experience similar to the Windows Forms NumericUpDown control. SpinDecorator also enables keyboard-based spinning; in fact you can hide the spin button UI to provide up-down spinning without the visual clutter. You can apply the SpinDecorator to any control with a numeric value property -- it isn't restricted to the WPF Elements numeric text boxes.
