I want to save information of TV programs faults. Each TV program has a number of different platforms. First user select the TV program then on the view I have a for each loop that shows the platforms that the specific TV program is available on.

I want to select in which platform we had video loss and select the quality of sound also.

I have defined disconnect object in the model that is the master table and the detail table is “disconnetdetails” that save the platforms that failure happened.

I want to create this list of details (disconnetdetails) in my view and pass it to controller.

In the view model :

 public Disconnect Disconnect { get; set; }

 // that shows the platforms available for selected TV program
 public List<Models.ProgramPlatform> objProgramList { get; set; }

 public List<Models.DisconnectDetails> objDisconnectDetails { get; set; }

 // for choosing quality of sound
 public IEnumerable<SelectListItem> Soundlist { get; set; }

 // for choosing quality of video
 public IEnumerable<SelectListItem> Videolist { get; set; }

In the view, I have:

 // shows available platforms 
 @foreach (var obj in Model.objProgramList)
 {
      DisconnectDetails o = new DisconnectDetails(); 
     
      <tr>
         <td>
             @obj.Platform.Name

             <input type="number" asp-for="@o.PlatformId " asp-items="  @obj.PlatformId" hidden /> 
         </td>
         <td>
             <select asp-for="@o.Sound" asp-items="@Model.Soundlist" class="form-select">
             <option disabled selected>-- --</option>
         </select>
         </td>
         <td>
             <select asp-for="@o.video" asp-items=" @Model.Videolist" class="form-select">
                 <option disabled selected>-- --</option>
             </select>
      </tr>
     
      @Model.objDisconnectDetails.AddRange(o); 
 }

In my controller, I have this code:

foreach (var o in obj.objDisconnectDetails)
{
    _db.DisconnectDetails.Add(o);
}

_db.SaveChanges();

I want to add DisconnectDetails to my list(objDisconnectDetails) in the view and send it to the controller to save to the database.
