RadzenCheckBoxList always retrieves null SelectedItems

Greetings,
I've been trying to get the SelectedItems, but it always comes null, can some one spot what I'm doing wrong?

<RadzenCheckBoxList Data="@MechanicalTasks"
                    TValue="string"
                    @bind-Values="@SelectedItems"
                    TextProperty="Descricao"
                    ValueProperty="Ui"
                    Orientation="Orientation.Vertical" />

@code{
 [Parameter]
 public List<TarefaModel> MechanicalTasks { get; set; }
 [Parameter]
 public List<string> SelectedItems { get; set; } = new List<string>();

 void onSave_RadzenButtonClick()
 {
     var selectedTasks = SelectedItems ?? new List<string>();
     DialogService.Close(new { KeyPress = "OK", SelectedItems = selectedTasks });
 }
}

Best Regards

Hi @Pedro_Horta,

You should use @bind-Value instead of @bind-Values. Here is a live demo showing that: Blazor CheckBoxList Component | Free UI Components by Radzen
