Hello ,

 I have a [] with 4 parmeters and I would like to display the db parameter and alow the user to select anther one (edit mode) 

how ever , the display as select is always the last parameter in the [] 

I think cod e will explain better 

in my controller : 

ViewBag.dis = new string[4] { "a", "b", "c", "d" };

in my view 

  @{var disss = "b"; } //value just to be clear 
                                    @foreach (var item in (ViewBag.dis))
                                    {
                                        if (item == disss)
                                        {
                                            <li class="radio space">
                                                <label>
                                                    <input type="radio" asp-for="District" value=@item checked="checked">
                                                  @item  <i class="fas fa-street-view"></i>
                                                </label>
                                            </li>
                                        }
                                        //  if (item != Model.District)
                                        if (item !=disss)
                                        
                                        {
                                            <li class="radio space">
                                                <label>
                                                    <input type="radio" asp-for="District" value=@item checked="">
                                                    @item <i class="fas fa-street-view"></i>
                                                </label>

In html the checked attribute does not require a value and it value is meaningless. If the attribute exists then the value is checked. like the example above don’t include the checked attribute if you don’t want it checked.
