HTML.Checkboxfor to Toggle button HTML?

Question

Is there anyway to convert the @HTML.Checkboxfor into toggle html button? I have refer the toggle button style from https://www.w3schools.com/howto/howto_css_switch.asp

Currently its working by using :

@Html.CheckBoxFor(model => model.IsEnabled, new { @checked = "checked", @Name = "DelegateChkBox" })

Changed to:

    <td class="slider-td">
         <label class="switch">
            <input name="DelegateChkBox" id="IsEnabled" type="checkbox" value="true" data-val-required="The IsEnabled field is required." data-val="true" data-bind="checked: IsEnabled">
          <div class="slider round"></div>
          </label>
   </td>

The toggle button only works and postback to controller if it's CHECKED:

else it won't postback to controller by default UNCHECKED :

Any help will be appreciated! Thanks!

Based from some experiments and findings, I found that you need to include hidden field generated by the helper (Html.CheckBoxFor) as shown by styling below:

<style type="text/css">
.switch {
  position: relative;
  display: inline-block;
  width: 60px;
  height: 34px;
}

.switch input {display:none;}

.slider {
  position: absolute;
  cursor: pointer;
  top: 0;
  left: 0;
  right: 0;
  bottom: 0;
  background-color: #ccc;
  transition: .4s;
}

.slider:before {
  position: absolute;
  content: "";
  height: 26px;
  width: 26px;
  left: 4px;
  bottom: 4px;
  background-color: white;
  transition: .4s;
}

/* include generated hidden field here */
input[type="checkbox"]:checked + input[type="hidden"] + .slider,
input[type="checkbox"]:checked + .slider {
  background-color: #2196F3;
}

/* include generated hidden field here */
input[type="checkbox"]:focus + input[type="hidden"] + .slider,
input[type="checkbox"]:focus + .slider {
  box-shadow: 0 0 1px #2196F3;
}

/* include generated hidden field here */
input[type="checkbox"]:checked + input[type="hidden"] + .slider:before,
input[type="checkbox"]:checked + .slider:before {
  transform: translateX(26px);
}

/* Rounded sliders */
.slider.round {
  border-radius: 34px;
}

.slider.round:before {
  border-radius: 50%;
}
</style>

View usage example (just change <input type="checkbox" /> to @Html.CheckBoxFor):

<label class="switch">
    @Html.CheckBoxFor(model => model.IsEnabled)
    <div class="slider round">
    </div>
</label>

To ensure the checkbox is being checked in client-side before doing postback, you can use jQuery code below:

// change event may modified to other events
$("#IsEnabled").change(function () {

    // check if checkbox is being checked
    // taken from /a/23007488 by Alexandru Chichinete
    if ($("#IsEnabled").is(":checked"))
    {
        // enable form submit
    }
});
