Remarks

DropDownList<TEnum> and OptionSelector<TEnum> are interchangeable when the data source is an enum. Both expose a typed Value property and a typed ValueChanged event. They differ only in appearance: DropDownList<TEnum> is a compact single-line dropdown, while OptionSelector<TEnum> shows all options as checkboxes.

The dropdown source is automatically populated from TEnum values in the constructor.

Usage Example: 

var dropdown = new DropDownList<DayOfWeek> ();
dropdown.Value = DayOfWeek.Monday;
dropdown.ValueChanged += (s, e) => Console.WriteLine ($"Selected: {e.Value}");

Constructors

DropDownList()

Initializes a new instance of the DropDownList<TEnum> class. Automatically populates the dropdown source from TEnum values.

Properties

Value

Gets or sets the currently selected enum value.

Events

ValueChanged

Raised when the selected value changes. Provides the new value as TEnum?.
