WPF Slider Control

How to Make a Slider Snap to Integer Values

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"
