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

Question

I am using CheckBox in my ASP.Net MVC project,

i want to set checkBox by default checked,

My CheckBox is

@Html.CheckBoxFor(model => model.         


        

Answer 1

You could set your property in the model's constructor

public YourModel()
{
    As = true;
}

Answer 2

An alternative solution is using jQuery:

    <script src="js/jquery-1.11.0.min.js" type="text/javascript"></script>
    <script type="text/javascript">
        $(document).ready(function () {
            PrepareCheckbox();
        });
        function PrepareCheckbox(){
            document.getElementById("checkbox").checked = true;
        }
    </script>

Answer 3

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

This will certainly work

Answer 4

My way is @Html.CheckBoxFor(model => model.As, new { @value= "true" }) (meaning is checked)

Answer 5

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

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

Answer 6

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.
