❔ Custom SelectListDialog Enum
I am using MudBlazor and I am having problems with creating a Custom Dialog which has a parameter of Enum and renders the Enum Values as the SelectList or DropDown, my Enums are, 
 public enum InputSelectList
    {
        Range,
        Values
    }

  public enum ParameterSelectList
    {
        Fix,
        Range,
        Values
    }
 public enum InputSelectList
    {
        Range,
        Values
    }

  public enum ParameterSelectList
    {
        Fix,
        Range,
        Values
    }
and an example of Custom Dialog in MudBlazor 
@inject ApplicationDbContext DataContext;
@inject IStringLocalizer<Resources> Loc

<MudDialog>
    <DialogContent>
        <MudTextField @bind-Value="_role" Label="Role" />
    </DialogContent>
    <DialogActions>
        <MudButton OnClick="Cancel">Cancel</MudButton>
        <MudButton Color="Color.Primary" OnClick="Submit">Ok</MudButton>
    </DialogActions>
</MudDialog>

@code {
    [CascadingParameter] MudDialogInstance MudDialog { get; set; }
    private string _role { get; set; }

    [Inject] ISnackbar Snackbar { get; set; }

    async Task Submit()
    {
        string normalizedRoleName = _role.ToUpper().Trim();

        if (!await DataContext.Roles.AnyAsync(r => r.NormalizedName == normalizedRoleName))
        {
            var newRole = new IdentityRole(_role);
            newRole.NormalizedName = normalizedRoleName;

            var result = await DataContext.Roles.AddAsync(newRole);
            await DataContext.SaveChangesAsync();

            if (result != null)
            {
                Snackbar.Add(@Loc["RoleAddedSuccessfully"]);
                MudDialog.Close(DialogResult.Ok(newRole));
            }
            else
            {
                Snackbar.Add(@Loc["ErrorAddingTheRole"]);
            }
        }
        else
        {
            Snackbar.Add(@Loc["RoleAlreadyExists"]);
        }
    }

    void Cancel() => MudDialog.Cancel();
}
@inject ApplicationDbContext DataContext;
@inject IStringLocalizer<Resources> Loc

<MudDialog>
    <DialogContent>
        <MudTextField @bind-Value="_role" Label="Role" />
    </DialogContent>
    <DialogActions>
        <MudButton OnClick="Cancel">Cancel</MudButton>
        <MudButton Color="Color.Primary" OnClick="Submit">Ok</MudButton>
    </DialogActions>
</MudDialog>

@code {
    [CascadingParameter] MudDialogInstance MudDialog { get; set; }
    private string _role { get; set; }

    [Inject] ISnackbar Snackbar { get; set; }

    async Task Submit()
    {
        string normalizedRoleName = _role.ToUpper().Trim();

        if (!await DataContext.Roles.AnyAsync(r => r.NormalizedName == normalizedRoleName))
        {
            var newRole = new IdentityRole(_role);
            newRole.NormalizedName = normalizedRoleName;

            var result = await DataContext.Roles.AddAsync(newRole);
            await DataContext.SaveChangesAsync();

            if (result != null)
            {
                Snackbar.Add(@Loc["RoleAddedSuccessfully"]);
                MudDialog.Close(DialogResult.Ok(newRole));
            }
            else
            {
                Snackbar.Add(@Loc["ErrorAddingTheRole"]);
            }
        }
        else
        {
            Snackbar.Add(@Loc["RoleAlreadyExists"]);
        }
    }

    void Cancel() => MudDialog.Cancel();
}
