How do I set a checkbox in razor view?

Question

I need to check a checkbox by default:

I tried all of these, nothing is checking my checkbox -

@Html.CheckBoxFor(m => m.AllowRating, new { @value = "true" })

@Html.CheckBoxFor(m => m.AllowRating, new { @checked = "true" })

@Html.CheckBoxFor(m => m.AllowRating, new { @checked = true })

@Html.CheckBoxFor(m => m.AllowRating, new { @checked = "checked"})

Answer 1

only option is to set the value in the controller, If your view is Create then in the controller action add the empty model, and set the value like,

Public ActionResult Create()
{
UserRating ur = new UserRating();
ur.AllowRating = true;
return View(ur);
} 

Answer 2

You should set the AllowRating property to true, preferably in the controller or model.
Like other inputs, the checkbox's state reflects the value of the property.

Answer 3

You can do this with @Html.CheckBoxFor():

@Html.CheckBoxFor(m => m.AllowRating, new{@checked=true });

or you can also do this with a simple @Html.CheckBox():

@Html.CheckBox("AllowRating", true) ;
