Refresh a table using AJAX in ASP.NET MVC

Question

I want to update a table in MVC using ajax. I already inserted the data into the database using ajax. I just want to update the table after inserting a new row.

PS. I tried searching, but nothing helped, I'm still confused.

Here is my code:

Main page View:

<div id="theTable">
    @Html.Partial("_IPTable") 
</div>
    <script src="~/Scripts/jquery-1.10.2.min.js"></script>
    <script src="~/Scripts/Admin.js"></script>"`

Partial page View:

<table id="table">`
    <tr>
        <th>ID</th>
        <th>Line</th>
        <th>Supplier</th>
    </tr>

    @foreach (var item in ViewBag.IPTable)`
    {
       <tr>
            <td>
                @item.ID
            </td>
            <td>
                @item.Line
            </td>
            <td>
                @item.Supplier
            </td>
        </tr>

    }
</table>enter code here

Controller view:

public ActionResult Admin()
        {
            // get data from database
            return View();
        }
public ActionResult _IPTable()
        {

            return PartialView();
        }

Ajax code to insert a new record:

 <script>
$(document).ready(function () {
//function will be called on button click having id btnsave
$("#btnSave").click(function () {
    $.ajax(
    {
        type: "POST", //HTTP POST Method
        url: "AdminInsert", // Controller/View
        data: { //Passing data
            //Reading text box values using Jquery
            Line: $("#txtLine").val(),
            Supplier: $("#txtSupplier").val()
        }
    });
});

}); </script>

You can create an action method that returns the HTML markup needed to display your table. Let me create a view model with which we will pass the table data.

public class ItemVm
{
  public string ItemId {set;get;}
  public string Line {set;get;}
  public string Supplier {set;get;}
}

, . / . . .

public ActionResult TableData()
{
  var items = new List<ItemVm>{
      new ItemVm { ItemId="A1", Line="L1", Supplier="S1" },
      new ItemVm { ItemId="A2", Line="L2", Supplier="S2" }    
  };
  return PartialView("TableData",items);
}

,

@model List<ItemVm>
<table>
@foreach(var item in Model)
{
  <tr><td>@item.ItemId</td><td>@item.Line</td></td>@item.Supplier</td></tr>
}
</table>

, , DOM . success ajax, . jQuery load DOM.

$(document).ready(function () {
   $("#btnSave").click(function () {

    $.ajax(
    {
        type: "POST", //HTTP POST Method
        url: "AdminInsert", // Controller/View
        data: { //Passing data
            //Reading text box values using Jquery
            Line: $("#txtLine").val(),
            Supplier: $("#txtSupplier").val()
        }
    }).success(function() {
           $("#theTable").load("/YourControllerName/TableData");
       });
});

. ItemVm, ViewBag.
