Hi,

I want to create an application that will work on browsers, tablets and smartphones. How do I start? is there anything special that I have to take into consideration from the beginning? I'm asking because I already created a browser application infrastructure using the templateLoader example that I found in one of your tutorials, and I'm also working with your router and I'm not sure that I'm in the right direction...It looks good on browser but that are the things that I have to think about if I want my app to work on other devices as well?

no toLowerCase method problem

I've been beating this dead horse for the last 2 weeks, on and off and still can't figure it out.

This is my datasource js:

var myDS = new kendo.data.DataSource({

transport: {

read: {

url: 'dataset.json'

,dataType: "jsonp"

,data: { select: "ID,NAME" }

}

},

schema: {

data: function(response) {

return response.features;

},

model: {

fields: {

"properties.ID": { type: "number" },

"properties.NAME": { type: "string" }

},

}

});

This is my dropdownlist init:

$("#dropdown").kendoComboBox({

placeholder: "...",

autoBind: false,

suggest: true,

dataTextField: "properties.NAME",

dataValueField: "properties.ID",

dataSource: myDS

});

This is my datasource table:

ID | NAME

-------------

1 | 0,4

2 | 6

3 | 10

4 | 20

5 | 35

6 | 110

7 | 220

8 | 400

The error 'Object doesn't support property or method 'toLowerCase'' pops up when trying to init the ddl - because my textfield values are basically numbers (but set as string in model and database!!), which are treated as strings - if I check the return values of datasource in Firefox and Chrome i see that my return values are treated as strings. The same goes for IE10 and above, but IE9 and IE8 treat those values as numbers, even if I've set the name field as string in datasource.

I've tried everything, I even went through all of the return rows of dataset and converted all of the name values to string, but that didn't help either. Not only that - if i try to print the response.features to console i get undefined in ie8/ie9 (what?).

Can anyone help me?

Javascript Classes Intellisense

Hi, im evaluating the Kendo Mobile UI with application framework to develop a hybrid app for Android and IOS.

Im using application Framework, separating classes using .js files.

The problem is that visual studio 2013 intellisense doesnt provide any help for class constructor (for example when i wrote new User() intellisense dont suggest the constructor parameters defined).

any idea?

/*
User = kendo.data.ObservableObject.extend({
init: function(username,nombre,apellido,email){
this.username = username;
}
});
*/

EXAMPLE FILES:

app.js

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

user : null,

loginService: null,

skin:'flat',

transition: 'slide',

initial : "views/account/login.html",

init: function () {

this.loginService = new LoginService();

if (this.loginService.loadLocalCredential())

this.initial = 'views/home/index.html';

}

});

login.js

LoginService = kendo.data.ObservableObject.extend({

username: "",

password: "",

isLoggedIn: false,

login: function () {

var that = this;

var url = 'http://url/Account/Login?username=' + this.username + '&password=' + this.password;

$.ajax({

url: url,

dataType: "json",

success: function (data, textStatus, jqXHR) {

if (data.result == true

) {

                          var user = new User(username,nombre,apellido,email); /* when i write new User() intellisense doesnt provide any help*/

that.set("isLoggedIn", true);

app.navigate("./views/home/index.html");

}

});

},

logout: function () {

this.clear();

app.navigate('./views/home/index.html');

},

clear: function () {

this.set('username', '');

this.set('password', '');

this.set('isLoggedIn', false);

},

loadLocalCredential: function () {

this.set('username', 'geoorge');

this.set('password', '1231');

this.set('isLoggedIn', true);

}

});

user.js

User = kendo.data.ObservableObject.extend({

username: "",

nombre: "",

apellido: "",

email: "",

isLoggedIn: false,

init: function(username,nombre,apellido,email){

this.username = username; this.nombre = nombre; this.apellido = apellido; this.email = email;

}

});

Thanks!

Block-out slots for All Day Event

Is there a way to block out the slots for an all day event, instead of having the event in the "all day" slot?

Fixed Width for Value Axis Labels

I need to be able to set a fixed width for the labels of the Value Axis. I have a problem caused by the re-scaling of the plotting area based on the number of digits in the valueAxis labels. I need some way to keep the actual chart area (compared to the value axis) to stay the same width, so that I can consistently line up with other elements on my page.

I can't seem to find any documentation and

valueAxis: {
labels:{
width: 100
},
width: 100,
},

does not work. Is this possible? PlotArea and ChartArea width also seems to have no effect.

Strange behavior of the "data-option-label" attribute

Hello,
I'm using MVVM approach in DropDownList configure. Everything works fine but I unexpectedly stuck on the "data-option-label" attribute value == "[ None ]". This value causes error "SyntaxError: Unexpected token N ". Using '[ .. ]' instead of '( .. )' is very important for our designer, so.. please take a look at jsFiddle example. Thank you.

addRow via jQuery automatically going to 2nd column

I have a batch editing grid where the user can add a new row either by clicking the Add button or tabbing off of the last editable column. The Add button works as intended...it adds a new row at the bottom of the grid and puts the keyboard focus in the first column of the new row.

The problem I am having is calling addRow programatically. It creates the new row at the bottom of the grid, but it automatically puts the keyboard focus in the second column of the new row. I want it to behave the same way as pressing the Add button. Here is the script that catches my keypress [TAB], and determines if it is the last row and last column (in my case it's column index 6).

function onDataBound(e) {

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

$(grid.tbody).on("keydown", "td", function (e) {

if (e.keyCode == 9)

{

var row = $(this).closest("tr");

var rowIdx = $("tr", grid.tbody).index(row);

var colIdx = $("td", row).index(this);

var count = grid.dataSource.total();

if(rowIdx == count-1 && colIdx == 6)

{

grid.addRow();

}

});

}

Any idea why my script is automatically moving it to the second column?

Thanks,
Jason

DatePicker - inline or attached to a custom control

We have a need of user date input into custom fields in 2 scenarios:
1) have datepicker inlined to the page (not as popup tied to a input control).
2) have it pop up next to a custom control, opened by a click on a separate button (so that it doesn't redraw/redraw the custom control).
After pick the date is actually populated/calculated to multiple controls on the page.

I tried to attach it to a hidden input (and handle all the data in eventhandlers) but in this case the picker widget is located at top-left corner of the window.

Are these scenarios possible?

scheduler scalability

I wonder what will happen if the number of tasks is high.
As I have understood it, the scheduler will ask the data source for all event regardless of how many they are.
