Class LinearMultiSelector<T>
A linear range view that allows selection of zero or more options from a typed list.
public class LinearMultiSelector<T> : LinearRangeViewBase<T, IReadOnlyList<T>>, IDisposable, ISupportInitializeNotification, ISupportInitialize, IOrientation, IValue<IReadOnlyList<T>>, IValue, IDesignableType Parameters
TThe data type of the options.

Remarks
Exposes the current selection through Value as IReadOnlyList<T>; the list is empty when no options are selected. A defensive copy is taken when Value is set, so the caller may mutate the list passed in without affecting subsequent reads.
Equality between the current value and a new value uses SequenceEqual<TSource>(IEnumerable<TSource>, IEnumerable<TSource>), so two distinct list instances with the same elements in the same order are considered equal.
Constructors
- LinearMultiSelector()
Initializes a new instance of LinearMultiSelector<T>.
- LinearMultiSelector(List<T>?, Orientation)
Initializes a new instance of LinearMultiSelector<T>.
Properties
- Value
Gets or sets the value.
Methods
- EnableForDesign()
Loads demo data suitable for a designer preview: a multi-select LinearMultiSelector<T> of the seven days of the week, with the five weekdays (Mon–Fri) preselected. 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.
