Class LinearRange<T>
A linear range view representing a contiguous range of options. The current value is a LinearRangeSpan<T> whose Kind is one of None, LeftBounded, RightBounded, or Closed.
public class LinearRange<T> : LinearRangeViewBase<T, LinearRangeSpan<T>>, IDisposable, ISupportInitializeNotification, ISupportInitialize, IOrientation, IValue<LinearRangeSpan<T>>, IValue, IDesignableType Parameters
TThe data type of the options.

Remarks
To switch between left-bounded, right-bounded, and closed range modes, set RangeKind. Setting RangeKind migrates the current Value, dropping fields that are no longer relevant.
To change the selection programmatically, set Value. Empty selections may be represented either by Empty or by a span of any LinearRangeSpanKind with no matching options.
Constructors
- LinearRange()
Initializes a new instance of LinearRange<T>.
- LinearRange(List<T>?, Orientation)
Initializes a new instance of LinearRange<T>.
Properties
- RangeAllowSingle
Gets or sets whether the range is allowed to collapse to a single option (only meaningful when RangeKind is Closed).
- Value
Gets or sets the value.
Methods
- EnableForDesign()
Loads demo data suitable for a designer preview: a closed range of work hours (8 AM through 6 PM in one-hour increments) with the range preset to "9 AM"–"5 PM". Only populated when
Tis string; for any other type, the view is left untouched and false is returned.
- OnSelectionChanged()
Called by the base when the selected indices have changed due to user input. Concrete subclasses must compute their Value from the current selection and raise ValueChanged / ValueChangedUntyped.
