                    DataSource="_forecasts" 
                    ValueProperty="TemperatureC" 
                    TextProperty="Summary" 
                    ShowSearch="true"                   
                    Change="(args) => Change(args)" />

    @foreach(var item in _events)
    {
        <span>@item</span>
        <br />
    }
}

@code 
{
    WeatherForecast[] _forecasts;
    List<string> _events = new List<string>();

    IEnumerable<int> _selectedItems = new List<int> { 1, 2, 3 }; //Is int because TemperatureC (ValueProperty) is int too

    protected override async Task OnInitializedAsync()
    {
        _forecasts = await ForecastService.GetForecastAsync(DateTime.Now);
    }

    void Change(IEnumerable<int> args)
    {
        _events.AddRange(args.Select(x => x.ToString()));
    }
