I am trying to read a Model class which should be populated with menu data from the database and then trying to bind that data to the Kendo Menu. I have copied the razor syntax given in the kendo docs (C# Version) and tried to convert it into VB.NET but i am getting an error that no bindto method accepts this many arguments and i can't figure what the error is? i have pasted the code as following, could someone please have a look and point me in the right direction (Menu and MenuItem are model classes)?

@Imports test.Models
@ModelType IEnumerable(Of MenuCategory)

@(Html.Kendo().Menu() _
            .Name("TestMenu") _
            .BindTo(Model,
                    Sub(mappings)
                            mappings.For(Of MenuCategory)(
                                Sub(x)
                                        x.ItemDataBound(
                                            Sub(item, menu)
                                                    item.Text = menu.Name
                                            End Sub) _
                                                    .Children(
                                                        Function(menu)
                                                                Return menu.SubItem
                                                        End Function)
                                        mappings.For(Of MenuItem)(

[Solved] RemoteView AJAX PartialView jQuery Not Defined

I am using remote views to show partial views from an ASP.NET MVC web site. I am performing ajax requests which in turn, use MVC partial views to replace part of the remoteView's DOM. This works fine... the first ajax post. On the second (or higher) - 2+ ajax posts, I get "Uncaught ReferenceError: $ is not defined".

Anyone have any thoughts?

Mobile index.html - RemoteView Navigate:

<body>

<div id="rootView" data-role="view" data-init="verifyLogin">

</div>

<script>

var isLoggedIn = false;

var app = new kendo.mobile.Application($(document.body), {

initial: "rootView"

});

function verifyLogin() {

app.navigate("http://127.0.0.2:81/Mobile/Account/Login");

}

</script>

</body

MVC Partial View:

<div data-role="view" data-title="Login" data-reload="true" id="viewLogin">

<form action="@OurApp.Core.Web.UrlHelper.GetUrlRoot()/Mobile/Account/Login" data-ajax="true" data-ajax-mode="replace" data-ajax-success="onSuccess" data-ajax-update="#loginForm" id="loginForm" method="post">

@Html.AntiForgeryToken()

<div>

<fieldset>

<header>

<legend>Login</legend>

</header>

<div class="widget-inner clearfix">

@Html.ValidationSummary(true, "Login was unsuccessful. Please correct the errors and try again.")

<div class="control-group">

<label class="control-label">@Html.LabelFor(model => model.UserName, new { @class = "bold" })</label>

<div class="controls">

@Html.TextBoxFor(model => model.UserName, new { autofocus = "autofocus", @class = "input-block-level", tabindex = "1" })

@Html.ValidationMessageFor(model => model.UserName)

</div>

<div class="control-group">

<label class="control-label clearfix">

@Html.LabelFor(model => model.Password, new { @class = "bold pull-left" })

</label>

<div class="controls">

@Html.PasswordFor(model => model.Password, new { @class = "input-block-level", tabindex = "2" })

@Html.ValidationMessageFor(model => model.Password)

</div>

<div class="clearfix">

<div class="pull-right" style="margin-left: 16px;">

<button type="submit" class="btn btn-primary disable-onclick" tabindex="4" style="margin-top: 0;">Login</button>

</div>

<div class="pull-right" style="margin-top: 6px;">

@Html.LabelFor(model => model.RememberMe, new { @class = "pull-left", style = "font-size: 12px;" })

@Html.CheckBoxFor(model => model.RememberMe, new { @class = "pull-left", style = "margin-left: 6px;", tabindex = "3" })

@Html.ValidationMessageFor(model => model.RememberMe)

</div>

</fieldset>

</div>

</form>

<script type="text/javascript">

$(function () {

var form = $("#loginForm");

form.removeData('validator');

form.removeData('unobtrusiveValidation');

$.validator.unobtrusive.parse(form);

});

function onSuccess() {

alert('success');

}

</script>

</div>

Controller Actions:

public ActionResult Login()

{

return PartialView(new LoginViewModel());

}

[HttpPost]

public ActionResult Login(LoginViewModel model)

{

return PartialView(model);

}

Kendo mobile ui with MVC - Render partial view using jquery ajax

I am creating a mobile compatible web application using Kendo Mobile UI. In my application, landing page is Login. After successful login, inbox of user having messages will be shown to user.

I want to implement slide effect after login. Means, the URL of application will remain same and only the content of the content will get rendered. Just like http://demos.kendoui.com/mobile/application/index.html

But the point is that I have to load view of Inbox after login.

To achieve this in MVC, I am using following code.

**On html page:**

    @model Bluestone.App.Mobile.Models.ViewLoginModel
        @{
          ViewBag.Title = "Login";
        }
    <section data-role="layout" data-id="default">
        <header data-role="header">
            <div data-role="navbar">
            Login
              </div>
        </header>
      </section>
        <div data-role="view" data-title="Login" id="viewlogin" data-layout="default" data-transition="overlay:up">
          <div id='loginHeader'>
            <h2>
              Please Log In</h2>
          </div>
          <div id='divLoginPanel'>

              @Html.TextBoxFor(m => m.Email, new { @class = "txtUserName", @placeholder = " Enter Email" })
              <span class="small-font value red ">@Html.ValidationMessageFor(m => m.Email)</span>
              <br />
              @Html.PasswordFor(m => m.Password, new { @class = "txtPassword", @placeholder = "Enter Password" })
              <span class="small-font value red ">@Html.ValidationMessageFor(m => m.Password)</span>
              <br />
              <a data-click="submit" data-role="button">Login</a>

          </div>
          <script>
            function submit(e) {
              var ViewLoginModel= new Object();
              ViewLoginModel.Username = $("#Email").val();
              ViewLoginModel.Password = $("#Password").val();
              $.ajax({ url: '@Url.Content("~/Account/Login")',
                type: "POST",
                data: ViewLoginModel,
                success: function (response) {
                  if (response != null) {
                    $(document.body).append(response);
                    var app = new kendo.mobile.Application();
                    app.navigate('#inbox');
                  }
                }
              });
            }
          </script>
        </div>


**And in Controller**

    [HttpPost]
        public ActionResult Login(ViewLoginModel model)
        {
          if (ModelState.IsValid)
          {
            if (ValidateUser(model.Email, password: model.Password))
            {
              return PartialView("Inbox");
            }
          }
          return null;
        }

**My Inbox View is**

    <section data-role="layout" data-id="inbox-default">
    <div data-role="footer">
        <div data-role="tabstrip">
            <a href="#actionsheet-view" data-icon="compose" >New</a>
            <a href="#Sent" data-icon="action" >Sent</a>
        </div>
    </div>

      </section>
    <div data-role="view" data-init="viewInit" data-layout="inbox-default" data-title="Inbox"
      id="actionsheet-view">
      <ul id="inbox" data-role="listview" data-template="inboxItem" class="messageList">
      </ul>
      <ul data-role="actionsheet" id="options" data-popup='{"direction": "left"}'>
        <li><a data-click="newMessage" id="btnnewMessage" href="javascript:void(0)" data-align="left"
          data-role="button">New Message</a> </li>
        <li><a id="btnAddInr" href="javascript:void(0)" data-action="addInr">Add INR</a></li>
      </ul>
    </div>
    <div data-role="view" data-title="Sent" id="Sent" data-layout="inbox-default" data-init="SentInit">
      <ul data-role="listview" id="SentInbox" data-template="inboxItem" class="messageList">
      </ul>
    </div>

Binding for the Inbox and Sent tabs is also there and my ajax request is also returning correct HTML. **But**, the layout i.e inbox-default is not applied when it gets rendered. Other way is to redirect to next view, but it will not give me slide effect which I want.

Kindly help on this.

Thanks in advance

string array in data template

Hi,

I have created a simple datasource wich gets a string array from a service.
The data that the service returns is in jsonp format.
The data the datasource returns is correct when i debug the code with chrome,
but i cant get it working with a datatemplate.

this is my code of the data-template:
<input type="checkbox"/>#: this#

but when i try to show this, I get a list of [Object] object.

How can I get the string value out of this object?

this post:
http://www.kendoui.com/forums/framework/mvvm/syntax-for-string-template-attr-binding.aspx

[Solved] Cleared textbox not being propigated to model

I have a grid with a client template view attached. In the template view I have a textbox inside a span that I hide or show depending on the value of a textbox next to it. When the hidden textbox is hidden I want to clear its value. In jquery the setting the value of the hidden textbox by $('textboxid').val(''); works visually but this not propegating to the model when I save. here is my Form with the jquery i'm trying to use in it.

@model Papr2WebMvc4.Models.PiprForms.Tobacco

@using (Html.BeginForm())

{

@Html.AntiForgeryToken()

@Html.ValidationSummary(true)

<h2>Edit Refering Tobacco users</h2>

<fieldset>

<legend></legend>

<div>

<label>Month</label>

@Html.TextBoxFor(model => model.Month)/@Html.TextBoxFor(model => model.Year)

</div>

<div>

<label>Number of peope referred this month to:</label>

<div>

<span>

<label>Quitline</label>

@Html.TextBoxFor(model => model.Count)

</span>

</div>

<div>

<span>

<label>QuitNet</label>

@Html.TextBoxFor(model => model.Count2)

</div>

<div>

<span>

<label>Local Cessation</label>

@Html.TextBoxFor(model => model.Count3)

</div>

</fieldset>

<script>

$(window).load(function () {

trace("Begin");

alert($('#Count3').val());

var localCessation = $('#Count3').val();

trace(localCessation);

});

$(document).ready(

function myfunction() {

trace("Begin");

$('#Count3').change(function (event) {

trace("Text Changed");

var text = $(this).val();

if (text) {

trace("Has Text");

$('.hiddenElement').show("fast");

}

else {

trace("No Text");

$('#FormName').val(null);

$('.hiddenElement').hide("fast");

}

});

</script>

}

Here is the grid it my form is connected to.

@(Html.Kendo()

.Grid<Papr2WebMvc4.Models.PiprForms.Tobacco>()

Is there something else I should be using to reset the textbox value so it is consumed by my model using javascript/jquery.

Possible bug with Adding/Concatenating

Hey guys,

I've noticed since upgrading recently that a few of my templates that have a plus (+) character in them:

#= x + y #
#= 'i' + Id #
etc...

are removing the '+' internally and throwing an invalid template exception.

I've gotten around this easily enough by moving my logic into a function and calling that within the template, however, this seems to be a bug, and I was just wondering if there was any official feedback on the issue.

EDIT: I should add I'm using Kendo v2013.1.319

Multiple filter in grid Toolbar template

Hi,

I have been following the example http://demos.kendoui.com/web/grid/toolbar-template.html with a variation and I'm stuck.

I have a grid with multiple dropdownlist and textbox for filtering a kendo grid result. I'm having a problem implementing this but specifically when i try to compare the field value and the value in one of my control (eg dropdownlist value) . I'm trying to compare it to a field in a model list - see Award.AwardTypeID. this might be the cause why it's not working

i have a html input button for the javascript

$('#btnSearch').on("click", function (e) {

refreshGrid();

return false;

});

function refreshGrid() {

$filter = new Array();

$filter.push({ field: "StudentID", operator: "contains", value: $('#txtStudentID').val() });

if ($('#AwardType').val()) {

$filter.push({ field: "Award.AwardTypeID", operator: "eq", value: $('#AwardType').val() });

}

var grid = $("#Grid").data("kendoGrid");

grid.dataSource.filter($filter);
