Load/Refresh only part of a page (View) using AJAX in ASP.NET MVC - ajax

Question

I am trying to achieve the same result as mentioned by the OP in this post However when I try to render partial view by checking if it was an AJAX request in my Index action, its evaluating to false.
My Index View:
#using (Ajax.BeginForm("Index", "Home",
new AjaxOptions()
{
HttpMethod = "GET",
InsertionMode = InsertionMode.Replace,
UpdateTargetId = "restaurantList"
}))
{
<input type="search" name="searchTerm" />
<input type="submit" value="Search By Name" />
}
#Html.Partial("_Restaurant",Model)
My Partial View:
<div id="restaurantList" style="border:2px dotted red; padding-left:2em; margin-top:4px;">
#foreach (var item in Model)
{
<div>
<h4>#item.Name</h4>
<div>#item.City, #item.Country</div>
<div>#item.CountOfReviews</div>
<hr />
</div>
}
</div>
My Index Action:
public ActionResult Index(string searchTerm = null)
{
var model = ...//Building model object here
if (Request.IsAjaxRequest())
{
return PartialView("_Restaurant", model);
}
return View(model);
I would prefer not to dive into use of any jQuery or javascript as I am in the process of learning ASP.NET MVC, and would want to know why the approach I took is not working? The second answer by Dennis, in the post that I referenced also suggested similar approach.
Could someone kindly tell me what I am doing wrong?
Thanks

This is just an example how you can load view from AJAX without page refresh, it may help you.
It send text value to controller by ajax call and load that value in other view which replace main view, if you don't want to replace main view then you can take other div instead same div to load content.
Controller:
public ActionResult Index()
{
return View();
}
[HttpPost]
public PartialViewResult TestAjax(string Name)
{
ViewBag.Name = Name;
return PartialView();
}
Index.cshtml:
<input type="button" id="btnSearch" class="btn btn-warning" style="height:35px;width:120px" value="Search"/>
<label>Name:</label><input type="text" id="txtName" name="txtName" />
<script>
$('#btnSearch').click(function () {
$.ajax({
url: '#Url.Action("TestAjax", "Home")',
data: { Name: $("#txtName").val() },
type: 'POST',
success: function (data) {
$("#divContent").html(data);
}
});
});
</script>
TestAjax.cshtml:
#ViewBag.Name

As #StephenMuecke pointed out in his comments, the libraries not being loaded correctly was the problem. While creating a new bundle of all libraries and adding it in the BundkeConfig.cs I had missed ~/Scripts/jquery.unobtrusive-ajax.js*. Got it working now.
