If you try to get two different arrays as you have showed in you controller-action code, there will be a trouble with text for non selected items, the array for check boxes will bind as expected but for descriptions will be different, just to be clear, check the following example:
Assuming We have a list with tree options:
100 - Foo
200 - Bar
300 - Zaz
If We set the following selection for items:
Foo, a
Zaz, c
If We take a look on the request, this is the raw request:
checklist = 100,300
Extradecription = a,null,c
So, the trouble is avoid to bind null descriptions for non selected options, this is complicated, in that case I recommend to you a clear solution:
Create a model to create entity process
Create a model for option
Add a list of option model in create entity model
Initialize the model to create a new entity
Render inputs in view using asp-for tag
Retrieve the request to create a new entity
I'll assume the name of models and properties to show how to bind a typed array in your request, change the names according to your scenario.
Create entity model:
public class CreateEntity
{
public CreateEntity()
{
Items = new List<SelectedItem>();
}
// Step 3
[BindProperty]
public List<SelectedItem> Items { get; set; }
// Another properties
}
Model for option:
public class SelectedItem
{
public bool IsSelected { get; set; }
public int Code { get; set; }
public string Name { get; set; }
public string Desc { get; set; }
}
Rendering the options list:
#for (var i = 0; i < Model.Items.Count; i++)
{
<input asp-for="#Model.Items[i].IsSelected" />#Model.Items[i].Name
<input asp-for="#Model.Items[i].Desc" />
<br/>
}
The GET and POST actions in controller:
[HttpGet]
public IActionResult CreateOption()
{
// Set the items list
var model = new CreateEntity
{
Items = new List<SelectedItem>
{
new SelectedItem{ Code = 100, Name = "Foo" },
new SelectedItem{ Code = 200, Name = "Bar" },
new SelectedItem{ Code = 300, Name = "Zaz" }
}
};
return View(model);
}
[HttpPost]
public IActionResult CreateOption(CreateEntity form)
{
// Retrieve only selected items
var query = form.Items.Where(item => item.IsSelected == true).ToList();
return View();
}
