How do I bind my InputText to a bool using ASP.net core

Question

<InputText class="input-checkbox100" id="ckb1" name="validateUSPSAddress" disabled="@true" @bind-Value="_model.CheckUSPSValidation" />

In my model, I have defined CheckUSPSValidation as

 public bool CheckUSPSValidation { get; set; }

The error I receive is the following. I don't understand why it's trying to convert bool to string

Severity Code Description Project File Line Suppression State Error CS1503 Argument 1: cannot convert from 'bool' to 'string' 219 N/A

I agree with Brian, you are using the wrong UI component for a boolean. — Mister Magoo

Don't mess with basic inputs. Browsers, especially phone browsers, often have special components for html input, and by-passing them like this could have unfortunate consequences for phone users. — Bennyboy1973

You have to convert it to bool and back to string. Binding has to be with a string:

<EditForm Model="mod">
  <InputText @bind-Value="@mod.checkString"/>
</EditForm>
Value: @mod.check
@code {

MyModel mod = new();
class MyModel
{
    public bool check { get; set; }
    public string checkString{get=>check.ToString();
    set{
        if(Boolean.TryParse(value, out bool val))
        check = val;
    }
    }
}
}

Working demo.
