Server paging and ListView's loadMore

In odata __next is specified to let the datasource know how to request more results. I'm using hand rolled json and my listview isn't showing the loadmore button. What do I need to do to let it know it should request the same URL but increment the page number?

var ds = new kendo.data.DataSource({

transport: {

read: {

url: "http://localhost:3000/api/anagram",

dataType: "jsonp",

data: {

format: 'html'

}

},

parameterMap: function(options) {

if (options.filter && options.filter.filters.length > 0)

return {

rack: options.filter.filters[0].value.replace(/\?/g,'-'),

format: 'html',

limit: options.pageSize,

page: options.page

};

return options;

}

},

group: 'length',

pageSize: 10,

page: 1,

sort: {field: 'w', dir: 'asc'},

filter: { field: 'rack', operator: 'eq', value: 'z' },

serverFiltering: true,

serverPaging: true,

serverGrouping: true,

serverSorting: true,

error: function(e){

alert(e);

console.log(e);

},

change: function(e) {

console.log('Data changed: ' + this.total());

},

schema: {

groups: 'groups',

total: 'count',

model: {

fields: {

length: {

type: 'number'

},

w: {

type: 'string'

},

f: {

type: 'string'

}

});

JSON ommit field if the value is null

Hi,
My json rest service omits fields when the values is null and looks like GRID can't handle such datasources.

Number is not null

{

{
    "id":"0422842A222780",
    "number":"0422842A222780"
  }

Number is null
{
    "id":"0422842A222780"
  }
model:{
    id:"id",
    fields:{
        id:{type:"string", editable:false},
        number:{type:"string", editable:false, nullable:true},
    }
}

As a result I see empty grid.
When I remove this field from displaying all works fine
Is there any solution?

Indexed db abstraction layer

I am wondering if telerik is planning on developing any kind of abrstraction layer for accessing indexed db architecture.

Quite annoyingly the W3C has killed WebSQL and indexed db is such a new standard that every browser that does support it (currently only 2 that I am aware of Chrom and FireFox) have there own way of managing the db and from what I am seeing IE 10- will have alltogetehr a different way to manage its indexed db implimentation.

This has long been a sore spot for me with open source development that standards are often not only times implimented accross differently accross platforms, but from version to version you can have entire subsets of functionality be cycled out (especially on new and rapidly evolving items like indexed db.. It make building stable applications that utilize these technologies exceedingly difficult.

I have not only a desire but a genuine need to see data storage for certain application fucntions occur on the client side but I cant do that without some kind of stability in the evolving landscape of the applications platform. I DEFINATELY dont desire to develope three seperate constantly shifting approaches to implimenting a client side data storage solution. Does Teelrik have any plans to impliment some kind of client side data storage abstraction layer that woudl allow you to utilize client side storage like indexed db with its controls sets?

Any ideas?

virtual scrolling and editable mutually exclusive?

Hey there,

While working on a CRUD demo using OpenAccess as Odata producer and KendoUI I'm facing with an issue with the command columns when virtual scrolling is enabled.
Virtual scrolling is working as expected in Firefox without the command columns: http://openaccess.spirit.de/.

Once the comand columns are enabled http://openaccess.spirit.de/?ReadWrite=1 it's no longer possible to use the scroll bar.

My guess is that the larger row height is causing this, but I haven't found time yet to dig deeper into it.

Thanks,

Rainer

Using a Kendo UI mobile icon without a button

Hi There,

Is there a way to use the mobile icons/images outside of a button (or with a tab strip, or listview etc.), so for example to display the search icon alone in a div using something like:

<div data-role="icon" data-icon="search"></div>

I'm trying to use the search icon, next to a search input tag for searches in my prototype.

Thanks,
Rob

URGENT : Issues with Grid Custom Editor Demo - Combobox in grid row

Dear Community,

We are evaluating KendoUI for our needs and here is one of the problem we have stuck on.

Problem Statement

We are trying to achieve almost similar to what is shown in demo http://demos.kendoui.com/web/grid/editing-custom.html.

Here is what we are doing.

We have a data source to fill the combo-box which will appear within the grid. It is basically a list of cities.

var cityDataSource = [{ CityID: 1, CityName: 'Delhi' }, { CityID: 2, CityName: 'Noida'}]

We also have main data source which contains lot more columns. Here you will observe that we have CityID as one of the fields.

var viewModel = kendo.observable({

gridSource: [

{ FirstName: "Shiva", LastName: "Wahi", CityID: 2, Title: "Module Lead", BirthDate: "10/29/1984", Age: 27 },

{ FirstName: "Priya", LastName: "Srivastava", CityID: 1, Title: "Tech Lead", BirthDate: "08/19/1982", Age: 30 }

]

});

In document.Ready function, we are preparing our data source (Please note CityName in fields section).

$(document).ready(function () {

var dataSource = new kendo.data.DataSource({

pageSize: 30,

data: viewModel.gridSource,

autoSync: true,

schema: {

model: {

fields: {

FirstName: { type: "string" },

LastName: { type: "string" },

CityName: "CityName",

Title: { type: "string" },

BirthDate: { type: "date" },

Age: { type: "number" }

}

});

There is a div tag on page called grid.

<div id="grid" />

Creating grid (Please note editor:cityDropDownEditor):

$("#grid").kendoGrid({

dataSource: dataSource,

pageable: true,

editable: true,

height: 260,

toolbar: ["create"],

columns: [

{

field: "FirstName",

title: "First Name",

width: 100

},

{

field: "LastName",

title: "Last Name",

width: 100

},

{

field: "CityName",

title: "City",

width: 100,

editor: cityDropDownEditor

},

{

field: "Title",

width: 75

},

{

field: "BirthDate",

title: "Birth Date",

width: 75,

template: '#= kendo.toString(BirthDate,"MM/dd/yyyy") #'

},

{

field: "Age",

width: 50

}

]

});

Here is the cityDropDownEditor function:

function cityDropDownEditor(container, options) {

$('<input data-text-field="CityName" data-value-field="CityName" data-bind="value:' + options.field + '"/>')

.appendTo(container)

.kendoDropDownList({

autoBind: false,

dataSource: cityDataSource

});

}

What do we want?

We want that when we click on the City column of the grid, dropdown should open up and when user changes the selection, it must reflect on the UI and as well as on my observable collection called viewModel.

But this is not happening at present. Our scenario is bit different from what is available in demo as there they are using CategoryName to bind both value and text fields of combo-box.

Please help as this is an urgent request and let me know if you need more details around this.

Regards,
Shiva

Datasource to a Webservice

I am a new KendoUI/Jquery/Javascript developer and I am having the following issue.
The ajax call is working ($.ajax(GetAirportList)), so I know the webservice is ok.
When the airportListDataSource is invoked, no data is loaded and the Javascript console (in Chrome) is
giving me the message "Uncaught RangeError: Maximum call stack size exceeded"

Please help!

var airportList = {};

var GetAirportList = {
type: "POST",
url: "OWLV2be.asmx/GetAirportList",
data: "{}",
contentType: "application/json; charset=utf-8",
dataType: "json",
success: function (msg) {
airportList = msg;
}
};

var airportListDataSource = new kendo.data.DataSource({
transport: {
read: {
type: "POST",
url: "OWLV2be.asmx/GetAirportList",
contentType: "application/json; charset=utf-8",
dataType: "json"
}
}
});

$(document).ready(function () {
$.ajax(GetAirportList);

$("#airpAirport").kendoDropDownList( {
dataTextField: "airportName",
dataValueField: "airportCode",
dataSource: airportListDataSource
});
