Make a checkbox checked or unchecked based on the value?

If you do not want to use @Html.CheckBoxFor for whatever reason and you'd like to stick to

         <input type="checkbox"> 

then this is what I found to be the best way to do it:

 <input @(Convert.ToBoolean(Model.YourPropertyHere) == true ?   "checked='checked'" : string.Empty)  type="checkbox" />

The code that @Yasser provided above:

    checked="@(required ? "checked" : "")"

Did not work for me because it was still adding the checked attribute to the element, and setting checked="" will still render the check box as checked, which was not the desired output, instead if you wrap the whole statement into a razor block like so:

     @(Convert.ToBoolean(Model.YourPropertyHere) == true ?   "checked='checked'" : string.Empty)

you will get the desired results.

if(condition = true)
{
@Html.CheckBoxFor(x => x.Test, new { @checked = "checked" })
}
else
{
@Html.CheckBoxFor(x => x.Test)
}

Hope this helps :)
