Radzen Drop Down List

Hi,
I'm trying the below code to populate a Radzen Drop Down List, using the code below, but when it renders the drop down list displays only:
'System.Linq.Enumerable+WhereListIterator`1[Radzen_Testing2025.Components.Pages.Testing+Role]'

Where am I going wrong please?

page "/Testing"
@using Radzen;
@using Radzen.Blazor;
@using System.Diagnostics;
<h3>Testing</h3>

<RadzenStack Orientation="Orientation.Horizontal" AlignItems="AlignItems.Center" JustifyContent="JustifyContent.Center" Gap="0.5rem" class="rz-p-sm-12">
        <RadzenDropDown AllowClear="true" AllowFiltering="true" FilterCaseSensitivity="FilterCaseSensitivity.CaseInsensitive" @bind-Value=@(employee.Roles) Multiple="true" Placeholder="Select..." Data=@roles Style="width:400px" />
</RadzenStack>

@code {
    
    class Employee
    {
        public IEnumerable<Role> Roles { get; set; }
    }

    class Role
    {
        public int Id { get; set; }
        public string Name { get; set; }
    }

    Employee employee;
    IEnumerable<Role> roles;

    protected override void OnInitialized()
    {
        roles = new List<Role>()
        {
            new Role {Id = 1, Name="Role1"}
            ,
            new Role {Id = 2, Name="Role2"}
        };

        employee = new Employee();
        employee.Roles = roles.Where(r => r.Id == 1);
}
}

Hi @Badgerless,

Please update your post to format the code according to the FAQ.
