DataGridSelectColumn: SetValue, consider ValueField if set

[David-Moreira]

Code to test:

<DataGrid TItem="Employee" Data="@employeeList" PageSize="5" Responsive Editable Filterable EditMode="DataGridEditMode.Popup">
     <DataGridSelectColumn TItem="Employee" Field="@nameof( Employee.Role )" Caption="Gender" Editable
                           Data="RolesNamesSource" ValueField="(x) => ((UsersRoles)Enum.Parse(typeof(UsersRoles), (string)x))" TextField="(x) => (string)x" />
     <DataGridCommandColumn />
 </DataGrid>

 @code {

    private List<Employee> employeeList = new List<Employee>() { new Employee( UsersRoles.Standard ), new Employee( UsersRoles.Premium ), new Employee( UsersRoles.Admin ) };
    private List<string> RolesNamesSource = Enum.GetNames( typeof( UsersRoles ) ).ToList();

    protected override void OnInitialized()
    {

        base.OnInitialized();

    }

    class Employee
    {
        public Employee( UsersRoles role )
        {
            Role = role;
        }

        public UsersRoles Role { get; set; }
    }

    enum UsersRoles
    {
        Standard,
        Premium,
        Admin
    }

}
