This control comes to simplify the process of coding for some UI design cases where you need to let your user choose a value and change it and you update your interface based on user's choices. A very common example is a slider control that lets user to zoom in or zoom out to view a photo.
If you just set the Minimum and Maximum of a slider and choose a value the result is determined by the pixel position of the thumb. The value is typically a high-precision value with many decimal places. To allow only integer values you have to set the IsSnapToTickEnabled property to True.

<Slider Minimum="0" Maximum="20" IsSnapToTickEnabled="True" TickFrequency="2"/> |
