See more:

@Html.CheckBoxFor(model => model.IsPrint, new { id = "sendCorrMail" }) @Html.LabelFor(m => m.IsPrint)

this is how I am checking the check box but the model.Isprint is not being passed as true when I auto select?

$('#sendCorrMail').attr('checked', 'checked');

Try like below

Put the below markup like below

@model SampleModel
@using (Html.BeginForm("PostCheckBox", "Sample", FormMethod.Post))
{
    @Html.CheckBoxFor(model => model.IsChecked, new { id = "sendCorrMail" })
    <input type="submit" value="Click"/>
}

Create a Model class

C#

namespace MVCFileUpload.Models
{
    public class SampleModel
    {
        public bool IsChecked { get; set; }
    }
}

Create an ActionResult

SQL

[HttpPost]
      public ActionResult PostCheckBox(SampleModel sampleModel)
      {
          return View("Index");
      }

Hope this helps

I was to resolve the issue with the help of Jquery... this is what I did to resolve the issue..

this is the hidden field I added...

@Html.HiddenFor(model => model.IsMailMandatory, new { @class = "hiddenIsMailMandatory" })

this is the jquery...

PHP

//to auto select the Mail if the mail is the only delivery option.
if ($('.hiddenIsMailMandatory').val() == 'True') {
    var $sendCorrMail = $('#sendCorrMail');
    var $hdnInput = $sendCorrMail.siblings('input[type="hidden"][name="' + $sendCorrMail.attr('name') + '"]');
    $sendCorrMail.prop('checked', true).attr('disabled', 'disabled');
    $hdnInput.val('true');
