ASP.NET Core Razor - post checkbox value as yes or no to database

Marius Vasile

5y1.4k.NET

I have the following checkbox

"checkbox" name="chk1" asp-for="MinPPE.Head" checked data-toggle="toggle" data-on="Not Required" data-off="Required" data-onstyle="danger" data-offstyle="success" data-width="150" data-height="50"/>

In the database, for MinPPE.Head I want to have Yes if checkbox checked (Required) and No if not (Not Required). How do I build my Post statement?

Accepted answer
if below code doesn't work then it means you are not getting true/flase , you have null value.
e => e.Head.ToString()=="True"?"Yes":"No" ;

Ok, I got functional, it is posting but now, how do I get the values for OnGet?
I want the checkboxes to be checked in true in the database and not checked if false
MinPPE = await _context.MinPPEs.Where(a => a.PTWNo == ptwNoId).DefaultIfEmpty().SingleOrDefaultAsync();
gives me error for null values

The error is that it cannot convert type 'string' to 'bool'.

Have you tried
e => e.Head==true?"Yes":"No"

I am using a Razor page, my Post looks like this
var newMinPPE = new MinPPE();
            if (await TryUpdateModelAsync(newMinPPE, "MinPPE",
                e => e. //this is where I have the result of the checkbox
                ))
            {
                _context.MinPPEs.Add(newMinPPE);
                await _context.SaveChangesAsync();
            }

You can convert bool to string
public void OnPostSubmit(PersonModel person)
    {
        this.Name = person.MinPPE.Head? "Yes" : "No";
    }
