Hi,

I created an Icenium mobile app that utilizes Kendo UI and Parse.com. I have already developed a Facebook Login function for the app. Now i Need the following additional functions:

- post a message ("Event") with some additional fields and select a Location via Google Maps
- search for events at a specific Location or at the current Location, result should be Shown either as a list or in map
- when launching the app, it Show automatically all Events near the current Position in a map
- when selecting an Event, it should Show up in a Detail view

Is there anybody out there who could accomplish this? (paid of course)

Best Regards
Jörg

Inline header filter row with groupable and pageable grid

I've extended a suggestion to my purposes from this post:
http://www.kendoui.com/forums/kendo-ui-web/grid/grid-header-filtering-row-that-contains-1-element-for-each-column-in-grid-with-the-same-width.aspx

I've gotten it to work very well with my grid implementation. The only problem I've run into that I'm not sure how to solve so far is that when a column is dragged to the group header it aligns the headers with my filter row just fine, but if you then go to page 2, the headers are suddenly misaligned though the filter row stays in place.

You can see what I mean in this jsfiddle. It seems the <th> element that's added to the header row to indent the rows and align the grid is being removed somehow

Any suggestions about how to correct this behavior would be greatly helpful.

Edit: Actually, paging doesn't seem to matter. Just whenever the grid repaints as it also happens when filtering after grouping or grouping a second column.

MVVM for Grid

Hello!
I using Grid on page and want to do some editing of cells.

var grid = $("#daily-tasks-detail-grid").kendoGrid({

dataSource: {

transport: {

read: {

url: '/json/ords',

dataType: 'json'

}

},

columns: [

{ title: "Worker"},

{ title: "Description" }

],

rowTemplate: kendo.template($("#rowTemplate").html())

}).data('kendoGrid');

I generate row on this template:

<script id="rowTemplate" type="text/x-kendo-tmpl">

<tr role="row">

<td role="gridcell"></td>

</tr>

<tr role="row">

<td role="gridcell"></td>

</tr>

</script>

How can I make the data-bind?
For example: <td role="gridcell"><input type="text" data-bind="value: value.name" /></td>

Multiple kendo.mobile.Application instances

Working on a Single App-page designed for tablets/desktops so we want to have a mobile look and feel.
Right now i am looking at 3 kendo.mobile.Application instances.
-one for the main page(2 views: 'main_page' and 'details_page'), also we have 2 way drawer planned for it.
-one app for the right drawer(a filters list(main view) and a new view for each filter 'edit mode')
-one app for the left drawer(a hierarchical list)
Working on this, but i have doubts.
Let me know if this should work(theoretically).

Thanks

layoutChange called too many times

I have a page with 4 splitters. I only want to receive a layoutChange event for a particular splitter. When I resize the window the layoutChange callback is executed 6 times. Within my callback I need to calculate the height of a pane (the height is auto and cannot be pulled from the splitter reference as far as I know). Height calculation is an expensive operation and there is noticeable delay when this happens 6 times in a row. I would prefer to avoid creating a counter and relying on a condition such as if modulus 6 equals 0, calculate height.

I've created the following fiddle to demonstrate my issue: http://jsfiddle.net/kUvLZ/.

Is there a better way to bind my callback that will reduce the number of callback executions?
I don't exactly understand how/why the layoutChange is being triggered like this. Helping me understand it more would probably answer the following related questions
I understand that the child splitter is probably listening to parent splitter resizes. But why 6 times? Why not 3 or 4?
Is there a problem with the splitter control that's causing it to fire this many times? I would expect a parent splitter (.references-wrap in my example) to receive all of the layoutChange events from children. I don't expect a child to have to listen to all of the layoutChanges above it.
Could an alternate bind event be created to make it so that layoutChange listens to all nested calls whereas something like paneLayoutChange would only be triggered once?

Help appreciated.

Grid sorting strings by "equals" not working

Hey guys I have some strings in my grid like "Machine2". When I try to sort by Starts with: "Machine2" everything works great. But when I use equals: "Machine2" I get nothing. Do you know what causes this problem or maybe if I can just leave Starts with sorting ability (which is sufficient). Also it only occurs when using strings cause when I have int numbers like 100 sorting with equals: "100" works just fine.

"Help" window action?

Are the any plans to add a "Help" action to the window?

This is something we are using with all our application, not just for windows, but for panels too.

See example of what Ext JS has: http://docs.sencha.com/extjs/4.1.3/#!/api/Ext.panel.Tool-cfg-type

Possible bug in flattenGroups private javascript function in kendo.binder.js

Hi,

I've just downloaded the new version (2013.2 716) of Kendo UI (also the same problem in 2013.1.514). I created a webservice which returns the desired json for a server groupable grid datasource. The result of the webservice:

{

"d": {

"Data": null,

"Groups": [

{

"aggregates": [],

"field": "Comment",

"value": "abc",

"hasSubgroups": false,

"items": [

{ "Id": 2, "Comment": "abc" },

{ "Id": 6, "Comment": "abc" }

]

},

{

"aggregates": [],

"field": "Comment",

"value": null,

"hasSubgroups": false,

"items": [

{ "Id": 110, "Comment": null }

]

}

],

"Total": 3

}

The setup of the grid and the viewmodel:

<!DOCTYPE html>

<html>

<head>

<title></title>

<link rel="stylesheet" href="http://cdn.kendostatic.com/2013.2.716/styles/kendo.common.min.css">

<link rel="stylesheet" href="http://cdn.kendostatic.com/2013.2.716/styles/kendo.default.min.css">

<script src="http://cdn.kendostatic.com/2013.2.716/js/jquery.min.js"></script>

<script src="http://cdn.kendostatic.com/2013.2.716/js/kendo.web.min.js"></script>

</head>

<body>

<script>

var viewModel = kendo.observable({

dataSource: new kendo.data.DataSource({

transport: {

read: {

url: "MyService.asmx/GetData",

dataType: "json",

contentType: "application/json; charset=utf-8",

type: "POST"

},

parameterMap: function (data, type)

{

return kendo.stringify({

take: data.take,

skip: data.skip,

sort: data.sort || [],

group: data.group || [],

filter: data.filter || null

});

}

},

schema: {

data: "d.Data",

total: "d.Total",

groups: "d.Groups",

model: {

fields: {

Id: { type: 'number' },

Comment: { type: 'string' }

}

},

pageSize: 100,

serverPaging: true,

serverFiltering: true,

serverSorting: true,

serverGrouping: true

}),

onItemSelected: function (e)

{

alert('checkbox clicked');

}

});

$(document).ready(function ()

{

kendo.bind(document.body, viewModel);

});

</script>

<div data-bind="source: dataSource" data-role="grid" data-groupable="true" data-pageable="false"

data-columns="[{ template: '<input type=\'checkbox\' data-bind=\'events: {click:onItemSelected}\'/>'},{ title:'ID', field: 'Id' },{ title: 'Comment', field: 'Comment' }]">

</div>

</body>

</html>

When I try to use the grouping feature i got a javascript error:

Uncaught TypeError: Object [object Object] has no method 'get'

I debugged it and I found that the problem is caused by the binding of the checkbox click event (if I remove the checkbox column everything works fine).
There is a function in kendo.binder.js:

01.function flattenGroups(data) {

02. var idx, length, result = [];

03.

04. for (idx = 0, length = data.length; idx < length; idx++) {

05. if (data[idx].hasSubgroups) {

06. result = result.concat(flattenGroups(data[idx].items));

07. } else {

08. result = result.concat(data[idx].items);

09. }

10. }

11. return result;

12.}

I think the code in line number 8 is not working well, if the data[idx].items is an ObservableArray (the concat adds the observable array as a single element to the result array). I found another implementation of flattenGroups in kendo.data.js:

01.function flattenGroups(data) {

02. var idx, length, result = [];

03.

04. for (idx = 0, length = data.length; idx < length; idx++) {

05. if (data[idx].hasSubgroups) {

06. result = result.concat(flattenGroups(data[idx].items));

07. } else {

08. result = result.concat(data[idx].items.slice());

09. }

10. }

11. return result;

12.}

By changing the flattenGroups in kendo.binder.js to the version of kendo.data.js, the problem resolved.

Is it a bug (the missing "slice()" from kendo.binder.js flattenGroups function), or am I missing something from my code?
