Sliders allow dragging a grip back and forth along a defined range

## Properties

- [AllowValueAfterRangeEnd](https://developer.rhino3d.com/api/rhinocommon/type/rhino.ui.userinterfaceslider/allowvalueafterrangeend.md): Set to true if you want to allow dragging of the slider grip after the end of the defined range.
- [AllowValueBeforeRangeStart](https://developer.rhino3d.com/api/rhinocommon/type/rhino.ui.userinterfaceslider/allowvaluebeforerangestart.md): Set to true if you want to allow dragging of the slider grip before the start of the defined range.
- [DigitPrecision](https://developer.rhino3d.com/api/rhinocommon/type/rhino.ui.userinterfaceslider/digitprecision.md): Number of digits of precision for the slider. If you want the slider to only represent integer values, set the Digits value to 0.
- [DisplayValue](https://developer.rhino3d.com/api/rhinocommon/type/rhino.ui.userinterfaceslider/displayvalue.md): Should the slider display the current value as text on the screen
- [HorizontalOrientation](https://developer.rhino3d.com/api/rhinocommon/type/rhino.ui.userinterfaceslider/horizontalorientation.md)
- [Range](https://developer.rhino3d.com/api/rhinocommon/type/rhino.ui.userinterfaceslider/range.md): The range of acceptable values for the slider
- [Value](https://developer.rhino3d.com/api/rhinocommon/type/rhino.ui.userinterfaceslider/value.md): Current value that the slider represents

## Methods

- [OnValueChanged](https://developer.rhino3d.com/api/rhinocommon/type/rhino.ui.userinterfaceslider/onvaluechanged.md): Called when the slider's value changes. The default implementation calls the ValueChanged event
- [ValueAsFormattedString](https://developer.rhino3d.com/api/rhinocommon/type/rhino.ui.userinterfaceslider/valueasformattedstring.md): Formatted string shown based on value and digit precision

## Events

- [ValueChanged](https://developer.rhino3d.com/api/rhinocommon/type/rhino.ui.userinterfaceslider/valuechanged.md): Event triggered when the slider's value changes
