bind-Value not working

[Daniel]

Hi, how do I bind-Value to a complex type in MultiSelect DropDown?

I've tried:

                    

                     <SfMultiSelect TValue="ICollection<PapelViewModel>" TItem="PapelViewModel" Mode="@VisualMode.Box" @bind-Value="@UsuarioView.Papeis"

                        AllowCustomValue=true>

                        <MultiSelectFieldSettings Text="Descricao" Value="Id"></MultiSelectFieldSettings>

                        <SfDataManager Adaptor="Adaptors.CustomAdaptor">

                           <DataAdaptorComponent TModel="PapelViewModel" Action="Papel/Listar">

                           </DataAdaptorComponent>

                        </SfDataManager>                  

                     </SfMultiSelect>

But it's not working, it brings data from the DataAdaptor, and I'm able so select the items. But the value is never

bound and doesn't throw any errors, also If I already brings data from the list, it's not shown in the DropDown box

PapelViewModel is a complex type and UsuarioView.Papeis contains a ICollection of PapelViewModel

I found a solution, changing the TValue from ICollection to a  List< PapelViewModel>

worked

Apparently the MultiSelect doesn't work with an Interface
