Dropdown from Enum in Grid

[Jonathan Rogers]

Hi all,

I am trying to bind an enum list to a Grid control in Blazor Server-side, but I am having difficulty. I have been through different iterations, but here is what I am trying now:

<SfGrid DataSource="@DeliverySystemTypes" AllowPaging="true" AllowSelection="true"
                            Toolbar="@(new List<string>() { "Add", "Edit", "Delete", "Update", "Cancel"})">
                        <GridEvents OnActionBegin="ActionBeginDeliverySystemType" OnActionComplete="ActionCompleteDeliverySystemType" TValue="DeliverySystemType"></GridEvents>
                        <GridPageSettings PageSize="20"></GridPageSettings>
                        <GridEditSettings AllowAdding="true" AllowEditing="true" AllowDeleting="true" Mode="EditMode.Normal" ShowConfirmDialog="true"
                                            NewRowPosition="NewRowPosition.Top"
                                            ShowDeleteConfirmDialog="true"></GridEditSettings>
                        <GridColumns>
                            <GridColumn Field=@nameof(DeliverySystemType.DeliverySystemTypeID) HeaderText="HospitalUser ID" IsPrimaryKey="true" Visible="false"></GridColumn>
                            <GridForeignColumn Field=@nameof(DeliverySystemType.Type) ForeignKeyField="Id" ForeignKeyValue="Text" ForeignDataSource="@Types" HeaderText="Type"></GridForeignColumn>
                            <GridColumn Field=@nameof(DeliverySystemType.DeliverySystemTypeName) HeaderText="Name"></GridColumn>
                            <GridColumn Field=@nameof(DeliverySystemType.Manufacturer)  HeaderText="Manufacturer"></GridColumn>
                            <GridColumn Field=@nameof(DeliverySystemType.Model) HeaderText="Model"></GridColumn>
                        </GridColumns>
                    </SfGrid>

And the model:

    private List<DeliverySystemType>? DeliverySystemTypes;
    private List<DeliverySystemLabelModel> Types;


    public class DeliverySystemLabelModel
    {
        public DeliverySystemLabel Id { get; set; }
        public string Text { get; set; }
    }


    protected override async Task OnInitializedAsync()
    {
        DeliverySystemTypes = await DeliverySystemTypeService.GetDeliverySystemTypeDetails();


        Types = new List<DeliverySystemLabelModel>();
        Types.Add(new DeliverySystemLabelModel { Id = DeliverySystemLabel.LINAC, Text = "LINAC" });
        Types.Add(new DeliverySystemLabelModel { Id = DeliverySystemLabel.HDR, Text = "HDR" });
        Types.Add(new DeliverySystemLabelModel { Id = DeliverySystemLabel.Co60, Text = "Co-60" });
        Types.Add(new DeliverySystemLabelModel { Id = DeliverySystemLabel.Superficial, Text = "Superficial" });
    }

Where the enum is DeliverySystemLabel. 

Does anyone have a good way to bind an enum directly to a Grid control to give the DropDown options. The is saving via EF Core, .NET 6 as well.
