Programmatically Working with Checkboxes in MVC

Question

Hello everyone and thanks for the help in advance. I am trying to understand how to set the value of a checkbox from a model in any other way then using some type of if logic. In other words, is there a way to set the value directly form the model. Any help would be appreciated.

Hi @Kmcnet

In an ASP.NET Core MVC application, you can bind the checkbox to a model property by using Tag Helper.

1.Model

public class YourModel
{
    public bool IsChecked { get; set; }
}

2.View

@model YourModel
<input type="checkbox" asp-for="IsChecked" />

3.Controller

public IActionResult Index()
{
    var model = new YourModel { IsChecked = true }; // Set default value here if needed
    return View(model);
}
