How to set a CheckBox by default Checked in ASP.Net MVC

You could set your property in the model's constructor

public YourModel()
{
    As = true;
}

@Html.CheckBox("yourId", true, new { value = Model.Ischecked })

This will certainly work

In your controller action rendering the view you could set the As property of your model to true:

model.As = true;
return View(model);

and in your view simply:

@Html.CheckBoxFor(model => model.As);

Now since the As property of the model is set to true, the CheckBoxFor helper will generate a checked checkbox.

Old question, but another "pure razor" answer would be:

@Html.CheckBoxFor(model => model.As, htmlAttributes: new { @checked = true} )
