Ajax.BeginForm preload data - ajax

I have this view and everything fine with Ajax.BeginForm:
<h2>Index</h2>
#using (Ajax.BeginForm("Search", new AjaxOptions {
HttpMethod = "GET",
InsertionMode = InsertionMode.Replace,
UpdateTargetId = "users"
})) {
<input name="q" type="text" />
<input type="submit" value="Search" />
}
<div class="table-responsive" id="users">
</div>
But, i have a little question.
Right now, when i open this page, there are no table with data - it loads only when form is submitted.
So, my question: is it possible to have preload data (without adding other code)?
When page is loaded, i would like to have already all data without filtering (input uses for filtering when value is typed and form submitted).

Just call your Search action from users div when the page loads. You may not specify any parameter or use the default one. I assume you have something like this:
public ActionResult Search(string q)
{
var users = _usersRepository.GetAll();
if(!string.IsNullOrEmpty(q))
users = users.Where(user => string.Equals(user.Name, q));
return PartialView("_Search", users);
}
And in the view:
<div class="table-responsive" id="users">
#Html.Action("Search")
</div>

How do I refresh a second partial view, after the first partial view is updated?

I have a page which has a partial view (it's a login form). When the submit button is clicked, it calls the controller and logs the person in and refreshes the login form to show that he is logged in.
I now need to update the portion of the screen that shows the login button, or if he is logged in, shows "Hello, Logged In user"
I have a partial view written that shows whether or not the person is logged in, but I don't know how to call it after the success of the first one. I know there is an OnSuccess event, and that seems to be where I would wire that up, but I am not sure how to do this.
#using (Ajax.BeginForm("Login", "Account", new AjaxOptions { InsertionMode = InsertionMode.Replace, UpdateTargetId = "loginSection", }))
{
<div id="loginSection">
...form omitted for clarity.
<input type="submit" value="Log in" />
</div>
}
This is the partial view that needs to be updated after the login.
<ul id="menu">
#if (Request.IsAuthenticated)
{
<text>
Hello, #User.Identity.Name
</text>
}
else
{
<ul>
<a onclick="openLoginWindow()">Login</a>
<a onclick="openRegisterWindow()">Register</a>
</ul>
}
Instead of using Ajax.BeginForm, use normal form and do the form posting with your custom code so that you can controll the success handler as you wish
<div id="login">
#using(Html.Beginform())
{
<input type="text" name="UserName" />
<input type="text" name="Password" />
<input type="submit" id="btnLogin" />
}
</div>
and the script which will listen to the submit button click event and send the form the action method.
$(function(){
$("#btnLogin").click(function(e){
e.preventDefault();
var _this=$(this);
var _form=_this.closest("form");
$.post(_form.attr("action"),_form.serialize(),function(res){
if(res.Status==="authenticated")
{
//Let's hide the login form
$("#login").hide();
$("#yourSecondDiv").html(res.PartialViewContent);
}
else
{
alert("Wrong password");
}
});
});
});
So the javascript code is expecting a JSON structure like below from the controller action
{
"Status":"Authenticated",
"PartialViewContent" : "<p>The markup you want to show</p>"
}
the PartialViewContent will hold the markup you want to show to the user.
public ActionResult Login(string UserName,string Password)
{
//to do : Build the JSON and send it back
}
This answer will tell you how send the markup of a partial view in a JSON property to client.
Here is what worked for me:
Added OnSuccess:
#using (Ajax.BeginForm("Login", "Account", new AjaxOptions {
InsertionMode = InsertionMode.Replace,
UpdateTargetId = "loginSection",
OnSuccess = "successfulLogin"
}))
{... details omitted.
Then added this:
function successfulLogin() {
$('#loginPartial').load('Account/LoginLinksPartial');
which calls in the controller:
public ActionResult LoginLinksPartial()
{
return PartialView("_LoginLinks");
}

mvc3 submit button not working

There is a Html.BeginForm contains Ajax.BeginForm and out side the Ajax.BeginForm there is one
submit button. But this submit button not working. If I take submit button before Ajax.BeginForm
it's working fine. Submit button inside the Ajax.BeginForm is also working fine. My question is that
why submit button is not working if I take submit button after the Ajax.BeginForm;
Thanks in advance.
#using (Html.BeginForm("AssignTestGet", "Test"))
{
using (Ajax.BeginForm("TestPreviewTemplate", "Test", new AjaxOptions { HttpMethod = "POST", InsertionMode = InsertionMode.Replace, UpdateTargetId = "template" }))
{
<button type="submit" id="questionId" name="questionId" value="#ViewBag.id" class="submit" style="margin-left:45px;margin-top:-15px;"></button>
<input type="hidden" id="templateId"value="#ViewBag.id" name="templateId" class="tr"/>
}
<div id="template">
#Html.Partial("_testTemplate", Model)
</div>
<input type="submit" value="submit" />
}
HTML do not support one form between another. It is the violation of HTML rule. So, When Parsing then it only parse Outer form not the inner Form and so the outer submit button do not work.
You can use two form Differently giving different Id.
#using (Html.BeginForm("AssignTestGet", "Home", FormMethod.Post, new { #id ="OuterForm" }))
{
<div id="template">
</div>
<input type="submit" value="submit" id="mymyb" />
}
#using (Ajax.BeginForm("TestPreviewTemplate", "Home", null, new AjaxOptions { HttpMethod = "POST", OnBegin="MyMy()", UpdateTargetId = "template" }, new { #id="innerForm"}))
{
<input type="submit" value="submit Inner" id="mymyba" />
}

partial view display with targeted div in MVC3 Razor view engine

My Controller Action is:
public ActionResult PVInPage()
{
return View();
}
public ActionResult ViewPage2()
{
return PartialView();
}
My Main View:
#using (Html.BeginForm("ViewPage2", "PartialViewInPage"))
{
<input type="submit" value="Call Page Two" />
}
<div id="DisplayPartilView">
#*display partial view *#
</div>
My Partial view Is :
#{
ViewBag.Title = "View Page 2";
}
<div style="width:500px; height:200px; background-color:Gray" >
<h1> This is my Partial view </h1>
</div>
Now I want to do : when i click submit button in my main view then my partial view arise in
My main view inner div with id="DisplayPartilView".
Thanks for response
If you want to load data/html into a page without navigating to a different page you need to use Ajax.
ASP.Net MVC provides a set of helpers to work with Ajax (they are all use jQuery.Ajax under the hood so you can always drop back to one level and write your ajax calls by hand).
But in your case the Ajax.BeginForm provides everything what you need:
So change your main view to:
#using (Ajax.BeginForm("ViewPage2", "PartialViewInPage",
new AjaxOptions() { UpdateTargetId = "DisplayPartilView" }))
{
<input type="submit" value="Call Page Two" />
}
<div id="DisplayPartilView">
#*display partial view *#
</div>
And to make it work you need to reference the following script in your main view or in your layout file after jQuery:
<script src="#Url.Content("~/Scripts/jquery.unobtrusive-ajax.js")" type="text/javascript"></script>
#using (Html.BeginForm("ViewPage2", "PartialViewInPage"))
will refresh page, that's why you need ajax
.serialize() to get data from all inputs and .ajax() to make post request, then set partial:
$('#DisplayPartilView').html(response);
In my project i am doing like this it's below
this is my button which is i click then my partial view load in my div like this
<script type="text/javascript">
$(function () {
$("#btnLode").click(function () {
$("#LodeForm").load("/City/ShowAllState", function () {
alert("Your page loaded Successfully !!!!!!!");
});
});
});
</script>
<div id="LodeForm">
</div>
and this is another solution for this problem
#using (Ajax.BeginForm("SearchCountry", "City",
new AjaxOptions
{
InsertionMode = InsertionMode.Replace,
HttpMethod = "Get",
LoadingElementId = "ajax-loader",
UpdateTargetId = "CountryListID",
}))
{
<input type="submit" value="search Country" data-autocomplete-source="#Url.Action("SearchCountry", "City")" />
}
<div id="CountryListID">
</div>
i think this will help you

MVC4 - Ajax.BeginForm and Partial view gives 'undefined'

I'm working on an activity booking and I'm having trouble using ajax.beginform with a partial view. When I click submit, it just goes to a new page and there is an 'undefined' in the top left corner. I have "../../Scripts/jquery.unobtrusive-ajax.min.js" in my layout page. What I want to do is when the user submits the form, the div "AjaxTest" gets updated with the partial view and the form is under the search results.
Here is what I have so far (I took out all the structure and styling so its easier to read):
Main View - Activities
#model Project.Models.ActivityModel
<div id="AjaxTest"></div>
#using (Ajax.BeginForm(new AjaxOptions
{
UpdateTargetId = "AjaxTest",
InsertionMode = InsertionMode.Replace,
HttpMethod = "POST"
}))
{
#Html.ValidationSummary(true)
#Html.TextBoxFor(x => x.Activity_CityName)
<div class="editor-label">
<strong>#Html.LabelFor(x => x.Activity_StartDate)</strong>
</div>
<div class="editor-field">
<input id="checkin" type="text" name="Activity_StartDate" />
</div>
#Html.TextBoxFor(x => x.Activity_EndDate)
#Html.DropDownListFor(x => x.Activity_NumAdults, AdultNum)
#Html.DropDownListFor(x => x.Activity_NumChildren)
#Html.DropDownListFor(x => x.Activity_ChildAge1, ChildAge)
#Html.DropDownListFor(x => x.Activity_ChildAge2, ChildAge)
#Html.DropDownListFor(x => x.Activity_ChildAge3, ChildAge)
<div class="submitbutton">
<input data-inline="true"type="submit" id="activity_search" value="Search" />
</div>
}
Controller
[HttpPost]
public ActionResult Activities(ActivityModel activitysubmission) {
return PartialView("PartialActivities_Success", activitysubmission);
}
Partial View - PartialActivities_Success
#model Project.Models.ActivityModel
<p>City: #Model.Activity_CityName</p>
<p>StartDate: #Model.Activity_StartDate</p>
<p>EndDate: #Model.Activity_EndDate</p>
<div>
<p><strong>Ticket</strong></p>
<p>Number of Adults: #Model.Activity_NumAdults</p>
<p>Number of Children: #Model.Activity_NumChildren</p>
<p>Child 1 age: #Model.Activity_ChildAge1</p>
<p>Child 2 age: #Model.Activity_ChildAge2</p>
<p>Child 3 age: #Model.Activity_ChildAge3</p>
</div>
Scripts in Layout Page
<script src="../../Scripts/jquery.unobtrusive-ajax.min.js" type="text/javascript"> </script>
<script src="../../Scripts/xdate.js" type="text/javascript"></script>
<script src="../../Scripts/xdate.i18n.js" type="text/javascript"></script>
<script src="#System.Web.Optimization.BundleTable.Bundles.ResolveBundleUrl("~/Scripts/js")"></script>
<script>
$(document).bind("mobileinit", function() {
// As of Beta 2, jQuery Mobile's Ajax navigation does not work in all cases (e.g.,
// when navigating from a mobile to a non-mobile page, or when clicking "back"
// after a form post), hence disabling it.
$.mobile.ajaxEnabled = true; // originally false.
});
</script>
I noticed one mistake in the code. Your div has an id Ajaxtest but the parameter you are passing to BeginRequest is AjaxTest the T is capital
Are you using MVC 4? I would make sure that UnobtrusiveJavaScriptEnabled is set to true in your WebConfig file. I believe it is by default, though. The only other thing I can think of is to verify that you have your other jQuery files and that they're being loaded in the right order. If you load your unobrusive jQuery file before the main one then it won't work.
You haven't specified which action to call when posting the Ajax form. Try changing it to this:
#using (Ajax.BeginForm("Activities", new AjaxOptions
{
UpdateTargetId = "AjaxTest",
InsertionMode = InsertionMode.Replace,
HttpMethod = "POST"
}))

ASP.NET MVC posting with Ajax.BeginForm returns blank view

I have a page that contains multiple inputs - I'm using Ajax.BeginForm to build a form for each set of inputs.
<% using (Ajax.BeginForm(new AjaxOptions() { InsertionMode = InsertionMode.InsertAfter, HttpMethod = "POST" }))
{ %>
<input class="smallInput" type="text" name="duration"/>
<input type="submit" value="Add" />
<% } %>
The controller looks like this
[AcceptVerbs("POST")]
public ActionResult AddExercise(FormCollection form)
{
// some save logic...
return Content(string.Empty);
}
This works - the data is submitted to my controller and is saved.
However, every time this happens my page is replaced by a blank page. If I explicitly return a View from my Action, that view appears instead. But I want it to submit the form, leaving my existing page in place as-is.
I wasn't including the MVC Ajax javascript files in my page. Adding those includes fixed the problem.
You need to specify the id of the DOM element that you want to be updated:
<% using (Ajax.BeginForm(new AjaxOptions() {
UpdateTargetId = "someID",
InsertionMode = InsertionMode.InsertAfter,
HttpMethod = "POST" }))
{ %>
<input class="smallInput" type="text" name="duration"/>
<input type="submit" value="Add" />
<% } %>
