Hey,

I got an Problem with my Application.

If I navigate through my Views and DetailViews the App works, but after a few clicks, the app stops working.

I click on an Element in my Listview, then I go back and press an other one and go back an so on...
Somtimes I can do that 20 times untill I can't click anything, but often I just can click 2 Times.

Any Idea?

Thanks a lot

Mobile back button error on click

Hi,

I am trying to use kendo.mobile.ui.BackButton inside a navbar, in a mobile web application (mvc.net).
When taping the button I get the following error and then nothing happens:

TypeError: Result of expression 'e' [undefined] in kendo.mobile.min.js:12

here is my layout code (i'm using kendo version 2012.3.1114):

<div data-role="layout" data-id="mobileLayout">
<header data-role="header">
<div id="headerNavBarDiv" data-role="navbar">
<a id="backBtn" class="nav-button" data-align="left" data-role="backbutton">Back</a>
<div id="homeIconDiv" class="smallTempHomeIcon"></div>
<a id="showProjectHistory" data-align="right" data-role="button" data-icon="icon historyLight" style="display: none"></a>
</div>
<div id="titleDiv"></div>
</header>
</div>
<script>
var app;
$(document).ready(function () {
app = new kendo.mobile.Application($(document.body), { layout: "mobileLayout" });
});
</script>

As I understand from your documentation and lots of forum reading - this should be an easy one, but nothing I tried worked (including using the data-click or adding 'href=#:back')

I'll more then appreciate your help in this matter.

Thanks,
Ety

Kendo DataSource (AJAX) "GET" / Custom Query

Below is a data source which connects to an external REST service. All is well, except when I want to do a query and not return the entire set of data. I need to URL encode with messageTo = xxx but I am unsure of the correct syntax in a Kendo datasource or if this is supported at all..



Are you able to assist? Source code below. The code in BOLD is not working



Best Regards,



Damien.





var dataSource = new kendo.data.DataSource({

serverPaging: true,

pageSize: 10,

transport: {

read: {

type: 'GET',

headers: {'X-Parse-Application-Id':'MY_AUTH_KEY','X-Parse-REST-API-Key':'MY_SECOND_KEY'},

url: " https://api.parse.com/1/classes/Messages",

data: "{ messageTo: 'USER_ID_HERE'}",

dataType: "json" // JSONP (JSON with padding) is required for cross-domain AJAX

},

schema: { // describe the result format

data: "results" // the data which the data source will be bound to is in the "results" field

}

});

JSON, Templates, and Binding to Kendo Mobile Lists

Hi,

When looking at the Twitter example I have adapted it with my own data.

http://demos.kendoui.com/mobile/listview/pull-with-endless.html

I need to make a slight change:
1. When tapping each 'row' I want it to highlight blue (is there a way I can get this to happen?)
2. When tapping anywhere on the row, it needs to run a function based on id="1" id="2" etc. How do I wrap the entire row with an a href="#" ????

Thanks.

What is the correct method to Bind events to <a> and <li> List elements?

Hi Kendo gurus,

I am wondering if I am doing something wrong.

Basically I have a couple of functions that check localStorage session variables and I want to bind the events to list elements within my Kendo mobile application.

I have a list view like so: KENDO LIST HTML
<li data-icon="globe"><a href="#page1">Page 1</a></li>
<li data-icon="reply"><a href="#page2">Page 2</a></li>
<li data-icon="settings"><a href="#page3">Page3</a></li>

Then a function that checks if the user is a guest, and re-directs them: JS:
function checkSession() {
if (localStorage.getItem("guest") == "true") {app.navigate('#pleaseregister');}else {app.navigate('#page1');}
};

I've tried:
#1. <li data-icon="globe"><a href="#" onClick="checkSession();">Page 1</a></li>
and:
#2. <li data-icon="globe"><a href="#" data-click="checkSession">Page 1</a></li>
#3. <li data-click="checkSession" data-icon="globe"><a href="#" >Page 1</a></li>

In example 1, onClick events fire in the web browser/emulator but not on physical device, it appears very unresponsive.
Example 2+ 3 does not work at all.

When I use a button like so:
<a data-icon="toprated" data-click="checkSession" data-role="button" style="width:90%; height:30px;">Create Listing</a>

It works! But I like the look of the list view.

If you could let me know if there is a special way of doing this, it would be very much appreciated, I've noticed several Kendo UI users on here asking this question and there doesn't seem to have been an answer given? It's driving me crazy.

Regards,

Damien.

Node keypress event

Hey,

I'm trying to find a way to bind an enter keypress event to some function, so that using only the keyboard, when a user presses enter on some node, it will lead to some action.

I wonder what is the correct way to do that.
I have a complicated template for each node, and I tried to bind the keydown event to a class I have in each node, but that didn't work (it did work for me with the click event though...)

Any advice?

Thanks,

datasource POST not working when sync is called

Hello,

I'm following the "Getting started with the Kendo UI datasource" video. All is going well until I reach the "create new item" part. Populating the grid from the source json file works just fine. Looking at the network tab of the developer tools in Chrome, a POST is never sent when the datasource.sync() is called.

I am using jquery 1.8.2, Kendo UI Q3 2012 SP1 and Chrome 24.0.1312.56.

My javascript is as follows:

dataSource = new kendo.data.DataSource({

transport: {

read: {

url: "data.json",

dataType: "json",

cache: false

},

create: {

url: "addItem.php",

type: "POST"

},

schema: {

model: myDataSource

}

});

Any help would be greatly appreciated.

grid configuration : how to add fields to dataSource.schema.model.fields at runtime

What is the proper way to add field objects at runtime to an incomplete, i.e. only partially defined, dataSource schema model fields object? While some of the model fields will be pre-defined as part of the grid configuration, some of the column-names of the grid will be based on fields that are not known at design-time; they will be the names of employees in a department, and so they are not known until the department is selected by the user. So fields have to be added to the model, and corresponding columns have to be added to the grid at runtime.

Date..........Tom...........Dick..............Harry..............Jane...............Liz
1/1/2013......90.............180...............23.....................65..................50
1/2/2013......65.............210...............19.....................99..................28
1/3/2013......25.............100...............89.....................54..................22
.
.
.
1/31/2013

or a different department:

Date..........Ralph.........Delores.......Fred.
1/1/2013......19.............120...............41
1/2/2013......57.............315...............29
1/3/2013......21.............246...............63
