RadRangeBase

Class

Represents an abstract base class for controls that define a range of values, supporting properties such as Minimum, Maximum, SmallChange, LargeChange, and current Value. This class enables functionality for manipulating the value within defined limits and supports automatic reverse behavior when the value reaches either endpoint. It provides robust event handling for value changes, enabling easy data binding and client-side control of the range's behavior in UI applications.
