this is my controller method to pass ViewModel

Angius•2y ago

What do you mean? Just

@model ModelsVM

<h1>@Model.Question.Whatever</h1>

<ul>
  @foreach (var thing in Model.OptionsList)
  {
    <li>@thing.Whatever</li>
  }
</ul>

@model ModelsVM

<h1>@Model.Question.Whatever</h1>

<ul>
  @foreach (var thing in Model.OptionsList)
  {
    <li>@thing.Whatever</li>
  }
</ul>

@model OnlineExam.Models.ViewModels.OptionsVM @{ ViewData["Title"] = "Edit"; } <h1>Question Edit</h1> <form method="post"> <div class="container"> <div class="row"> <h4>Edit Question or Add Options</h4> </div> </div> <div> <label asp-for="question.question">Question</label> <input asp-for="question.question" /> <span asp-validation-for="question.question"></span> </div> @foreach(var obj in Model.OptionsList) { <div> <label asp-for="@obj.option"></label> <input asp-for="@obj.option" disabled/> </div> } @<div> <label asp-for="OptionsList"></label> <input asp-for="@obj.option" /> </div> <div> <label asp-for="@obj.option"></label> <input asp-for="@obj.option" disabled /> </div>@ <button type="submit" class="btn btn-primary">Update</button> <a asp-controller="Question" asp-action="Index">Go Back</a>
</form> this my view

Yeah And what doesn't work about it? Ah, wait, the issue is with how to create the form? So that it sends multiple fields to the controller?

mer_nam hai bulla rakhta hu kulaOP•2y ago

yes

Angius•2y ago

Might need to name those fields manually That is,

@for(var i = 0; i < @Model.Questions.Length; i++)
{
    <input type="text" name="Questions[@i]" id="Questions[@i]">
}

@for(var i = 0; i < @Model.Questions.Length; i++)
{
    <input type="text" name="Questions[@i]" id="Questions[@i]">
}

and you should be able to get it with

public async Task OnGet(List<string> Questions)
{

}

public async Task OnGet(List<string> Questions)
{

}

Angius•2y ago

Then add those 4 input fields

mer_nam hai bulla rakhta hu kulaOP•2y ago

Angius•2y ago

That is,

@for(var i = 0; i < @Model.Questions.Length; i++)
{
    <input type="text" name="Questions[@i]" id="Questions[@i]">
}

@for(var i = 0; i < @Model.Questions.Length; i++)
{
    <input type="text" name="Questions[@i]" id="Questions[@i]">
}

and you should be able to get it with

public async Task OnGet(List<string> Questions)
{

}

public async Task OnGet(List<string> Questions)
{

}

With naming them manually? Ah, wait, I think I can see the issue... Each answer has its own ID and stuff, so just sending a list of strings won't do

mer_nam hai bulla rakhta hu kulaOP•2y ago

yes thats why i added Option as Ienumarable<Option> in ViewModel that option is connected to Question Model vie FK

Angius•2y ago

Unless, perhaps,

@foreach(var q in Model.Questions)
{
    <input
        type="text"
        name="Questions[@q.Id]"
        id="Questions[@q.Id]"
        value="@q.Body">
}

@foreach(var q in Model.Questions)
{
    <input
        type="text"
        name="Questions[@q.Id]"
        id="Questions[@q.Id]"
        value="@q.Body">
}

public async Task OnPost(Dictionary<int, string> Questions)
{

}

public async Task OnPost(Dictionary<int, string> Questions)
{

}

Also, as a side note, line 59 of QuestionsController

  if(id == null&&id==0)

  if(id == null&&id==0)

id cannot be both null and 0 at the same time In any case, try the dictionary If that fails, I'm out of ideas, sorry
