In relation to this question:
StackOverflow - Grouping radio buttons in c# mvc
I have managed now to load and save the selected options from the form into a database but now the user may need to edit this.
How do I load the view with the selected user's choices? I cannot see where you can set selected Answer. On load I am getting the default values selected
用这个:
<%= Html.RadioButtonFor(m => m.Something, "something", new { Checked = "checked" })%>
You can set the SelectedAnswer
property value for each Course
in your GET
action and your EditorTemplate
will take care of the rest.
public ActionResult Index()
{
var vm= new OrderViewModel();
//the below is hard coded for DEMO. you may get the data from some
//other place and set the course and options
var q1 = new Course { ID = 1, Name= "Starters" };
q1.Options.Add(new Option{ ID = 12, Title = "Prawn Cocktail " });
q1.Options.Add(new Option{ ID = 13, Title = "Soup" });
q1.SelectedAnswer = 13; //to do : get the selected answer value from DB
vm.Courses.Add(q1);
var q2 = new Course { ID = 1, Name= "Mains" };
q2.Options.Add(new Option{ ID = 42, Title = "Beef" });
q2.Options.Add(new Option{ ID = 43, Title = "Lamp" });
q2.SelectedAnswer = 16;// to do :get the selected answer value from DB
vm.Courses.Add(q2);
return View(vm);
}
There is no change to be made to your editor template. It stays same as the previous answer.
@model Course
<div>
@Html.HiddenFor(x=>x.ID)
<h3> @Model.Name</h3>
@foreach (var a in Model.Options)
{
<p>
@Html.RadioButtonFor(b=>b.SelectedAnswer,a.ID) @a.Title
</p>
}
</div>
