Property Value

Type	Description
IEnumerable<TValue>	The List Box’s values/items.

Remarks

Use the Values property to access to the List Box’s list of item values/items from a bound data source. To respond to selection changes, handle the ValuesChanged event.

The Values property can return the following objects:

• If the ValueFieldName property is specified, the Values property includes the selected item’s values.
• If the ValueFieldName property is not specified, the Values property includes selected items.

<DxListBox Data="@Staff.DataSource"
          TextFieldName="@nameof(Person.Text)"
          @bind-Values="@SelectedStaff">
</DxListBox>

@code {
    IEnumerable<Person> SelectedStaff { get; set; } = new List<Person>() { Staff.DataSource[0] };
}

The code below demonstrates a sample implementation of the Person class.

public class Person {
    public int Id { get; set; }
    public string FirstName { get; set; }
    public string LastName { get; set; }
    public Department Department { get; set; }

    public string Text => $"{FirstName} {LastName} ({Department} Dept.)";
}
