Bhavik Solanki: Ajax Save

Hi,

Here I explain how to save form data using Ajax jquery so using this way page will not post back and data will be save.

So now let’s look how I have done

Here is my Simple View

   1:  @model MvcApplication1.Model.UserInformation

2:

   3:  @{

   4:      ViewBag.Title = "Index";

   5:      Layout = "~/Views/Shared/_Layout.cshtml";

   6:  }

7:

   8:  <h2>Index</h2>

9:

  10:  <script src="@Url.Content("~/Scripts/jquery.validate.min.js")" type="text/javascript"></script>

  11:  <script src="@Url.Content("~/Scripts/jquery.validate.unobtrusive.min.js")" type="text/javascript"></script>

  12:  <script type="text/javascript">

  13:      $(document).ready(function () {

14:

15:

16:

  17:          $("#dplist").change(function () {

  18:              if (this.value == 2) {

19:

  20:                  $("#txtbox").attr('style', 'Display:inline');

  21:              }

  22:              else {

  23:                  $("#txtbox").attr('style', 'Display:none');

  24:              }

  25:          });

26:

  27:      });

28:

  29:      function AjaxSave() {

30:

  31:          var rowData = $("#" + document.forms[0].id).serialize();

  32:          var url = '/Home/AjaxSave';

33:

  34:          $.post(url, rowData, function (JsonData) {

35:

  36:              debugger;

37:

  38:          });

39:

  40:      }

  41:  </script>

42:

  43:  @using (Html.BeginForm(null, null, FormMethod.Post, new { id = "signupform" }))

  44:  {

  45:      @Html.ValidationSummary(true)

  46:      <fieldset>

  47:          <legend>UserInformation</legend>

48:

  49:          <div class="editor-label">

  50:              @Html.LabelFor(model => model.Name)

  51:          </div>

  52:          <div class="editor-field">

  53:              @Html.EditorFor(model => model.Name)

  54:              @Html.ValidationMessageFor(model => model.Name)

  55:          </div>

56:

  57:           <div class="editor-label">

  58:              @Html.LabelFor(model => model.City)

  59:          </div>

  60:          <div class="editor-field">

  61:              @Html.EditorFor(model => model.City)

  62:              @Html.ValidationMessageFor(model => model.City)

  63:             </div>

  64:             <div class="editor-field">

  65:              @Html.DropDownList("dplist",(SelectList) ViewBag.DpList)

  66:              @Html.TextBox("txtbox")

  67:             </div>

68:

  69:          <p>

  70:              <input type="submit" value="Save" />

  71:              <input type="button" onclick="javascript:AjaxSave();"  value="AjaxSave" />

  72:          </p>

  73:      </fieldset>

  74:  }

75:

  76:  <div>

  77:      @Html.ActionLink("Back to List", "Index")

  78:  </div>

Here is My Controller

   1:  using System;

   2:  using System.Collections.Generic;

   3:  using System.Linq;

   4:  using System.Web;

   5:  using System.Web.Mvc;

   6:  using MvcApplication1.Model;

7:

   8:  namespace MvcApplication1.Controllers

   9:  {

  10:      public class HomeController : Controller

  11:      {

  12:          //

  13:          // GET: /Home/

14:

  15:          public ActionResult Index()

  16:          {

  17:              initilization();

  18:              return View();

  19:          }

20:

  21:          public void initilization()

  22:          {

  23:              ViewBag.bhavik= "Bhavik Test";

  24:              List<SelectListItem> LiList=new List<SelectListItem>();

  25:              AddItemInlist("One", 1, LiList,  false);

  26:              AddItemInlist("Two", 2, LiList, false);

  27:              AddItemInlist("Three", 3, LiList, true);

  28:              AddItemInlist("Founr", 4, LiList, false);

  29:              AddItemInlist("Fibe", 5, LiList, false);

  30:              ViewBag.DpList = new SelectList(LiList, "Value", "Text");

31:

  32:          }

33:

  34:          public void AddItemInlist(string Key,Int32 value, List<SelectListItem> addtolist,bool IsSelected)

  35:          {

  36:              SelectListItem Li = new SelectListItem();

  37:              Li.Text = Key;

  38:              if (IsSelected)

  39:              {

  40:                  Li.Selected = true;

  41:              }

  42:              Li.Value =value.ToString();

  43:              addtolist.Add(Li);

44:

  45:          }

46:

  47:          [HttpPost]

  48:          public ActionResult Index(UserInformation u)

  49:          {

  50:              initilization();

51:

52:

  53:              return View();

  54:          }

55:

  56:          [HttpPost]

  57:          public ActionResult AjaxSave(FormCollection form)

  58:          {

  59:              //Write Message what you want to display after save operation

  60:              string Name = form["Name"];

  61:              string Cist = form["City"];

  62:              string msg="Successfully Save Data";

  63:              return Json(msg);

  64:          }

65:

  66:      }

  67:  }

Now Look how it’s Work

Details:

Quick Point that need to take care

I have 2 button Save and AjaxSave.
Save will Work as data will post and redirect page.
Using Ajaxsave I have Ajaxcall using post method.
I need to pass all filed value on controller for that I have collect all fields value using
$("#" + document.forms[0].id).serialize(); pass this value in parameter $.post(url, rowData, function (JsonData) {
Now Look at JsonData that will retrurn from Controller

string msg="Successfully Save Data";
return Json(msg); You can use it to display message for what transaction has been happen
