BBlazor WASM Enum binding

I use Blazor WASM .NET Standard 2.1 and Radzen library for my components. The client can choose measure type from the Razden dropdown, the problem is when I want to edit this product the dropdown did not populate with the correct measure but with first from enum.

<RadzenDropDown @bind-Value="@model.Measure"
                AllowClear="true"
                Placeholder="Избери категория..."
                Data="@MyTypes" style="width: 100%;"
                TextProperty="EnumName"
                ValueProperty="EnumValue"
                Name="Measure">
</RadzenDropDown>

public enum Measure
{
    part,
    kilogram,
    gram
}

public class EnumMyTypes
{
     public Measure EnumValue { get; set; }
     public string EnumName { get; set; }
}

// list for the dropdown
List<EnumMyTypes> MyTypes { get; set; } = new List<EnumMyTypes>();

protected override async Task OnInitializedAsync()
{
    this.model = await this.ProductsService.DetailsAsync<ProductsRequestModel>(this.Id);
    this.categories = await this.CategoriesService.All();

    foreach (var item in Enum.GetValues(typeof(Measure)))
    {
        MyTypes.Add(new EnumMyTypes { EnumName = item.ToString(), EnumValue = (Measure)item });
    }
}
