(I am NOT saying this is a bug, What I am saying is my brain needs training :-) )

I have a TABLE that is DataBound to an ObservableArray (called vm.ServerData).

<div id="ServerTable" class="row Block InfoTable ">

<table>

<thead>

<tr>

<th>ACTION</th>

<th>Type</th>

<th>Class</th>

<th>Status</th>

<th>Size</th>

</tr>

</thead>

<tbody data-bind="source: ServerData"

data-template="serverTemplate"></tbody>

</table>

</div>

The body of the table is bound to the values in the Array via the data-template as follows:

01.<script type="text/x-kendo-template" id="serverTemplate">

02. <tr data-path="${Path}"

03. data-filecount="${FileCount}"

04. data-maxzoom="${MaxZoom}"

05. data-date="${Date}"

06. data-type="${Type}">

07. #if(Newer == "NEW") { #

08. <td><div class="button radial Center ButtonText">Download</div></td>

09. #} else { #

10. <td title="Already Downloaded"><img src="../images/pushPin.png" style="width: 32px; height: 32px;" /></td>

11. #}#

12. <td><span data-bind="text: Type" /></td>

13. <td><span data-bind="text: Class" /></td>

14. <td><span data-bind="text: Newer" /></td>

15. <td><span data-bind="text: Size" /></td>

16. </tr>

17.</script>

Everything works fine the first time the page is entered. The issue is that the user can issue commands that update the ServerData[i[.Newer field.

They update is done in code as follows:

if ((dd.Type == sd.Type) && (dd.Date >= sd.Date)) {

vm.ServerData[i].set("Newer", "CURRENT");

}

What I observe, is that the TD (line #14) updates just fine. But the IF/THEN/ELSE condition (lines 7-11) is not getting executed. [What is odd is that lines #7-11 are executing properly the first time the page is updated. So it is clearly that the change from the text of "NEW" -> "CURRENT" in via SET() that is not firing a change in the template code.

OK,

I can do a crude force of the issue by adding line #4 below:

1. if ((dd.Type == sd.Type) && (dd.Date >= sd.Date)) {

2. vm.ServerData[i].set("Newer", "CURRENT");

3. }

4.kendo.bind($("#ServerTable"), vm.ServerData);

And this will force the IF/THEN/ELSE to execute and my page works. But I think I am doing something very brutal to the KENDO MVVM paradigm (actually,
I am violating the whole MVVM concept). So pray tell, What is the elegant way to do this?

DataSource does not call create

Hi all!

I am very beginner in Kendo, so sorry if I ask stupid questions :)
I have the following code:

    var template = kendo.template($("#todo-template").html());

    var dataSource = new kendo.data.DataSource({
        transport: {
            read: {
                url: "api/todos",
                dataType: "json"
            },
            create: function () {
                alert("DSA");
            }
        },
        schema: {
            model: { id: "TODOID" }
        },
        change: function () { // subscribe to the CHANGE event of the data source
            $("#todo-table tbody").html(kendo.render(template, this.view())); // populate the table
        }
    });
    dataSource.read();

    $("#add-button").click(function () {
        dataSource.add({
            "TODOID": 30,
            "TITLE": "asd",
            "PRIORITY": 3,
            "DEADLINE": "2013-02-02",
            "DONE": false
        });

        dataSource.sync();
    });

The problem is that the create event is never being called. The read is okay, the table is shown nicely. What would be the problem?

Sincerely,
Daniel

NavBar Title Translation

I have a phonegap 3 application where I use kendo mobile.

For internationalization I use this:
https://github.com/plang/phonegap-l10n
It's pretty simple. I can add a class an the translation works.

My views:

<div data-role="view" id="tab-catalog" data-title="Catalog" data-layout="mobile-tabstrip">

....

</div>

<div data-role="view" id="tab-account" data-title="Account" data-layout="mobile-tabstrip">

....

</div>

My Layout:

<div data-role="layout" data-id="mobile-tabstrip">

<header data-role="header">

<div id="navbar" data-role="navbar">

<a data-role="button" data-rel="drawer" href="#drawer" data-icon="drawer-button" data-align="left"></a>

<span data-role="view-title"></span>

<a id="scan" data-align="right" data-icon="camera" data-role="button"></a>

</div>

</header>

</div>

Works fine.. but I don't know how to translate the data-title attribute.
I know I can set the title with
$("#navbar").data("kendoMobileNavBar").title("foo");
I also could read the title of my view with kendo.view().title and make the translation, something like this:

$("#navbar").data("kendoMobileNavBar").title(Localization.for(kendo.view().title));

After I start the app is the title is translated, but if I change the view and come back the title is "Catalog" again.

How could I accomplish anything like this?

How to make axis label shown in multiple lines

I would like to show each x axis label in two line, e.g., I want to show a date label
2013-12-23 14:59:00
as two lines formatting:
14:59:00
2013-12-23

if I just show x axis in one line, then the labels are too long and will overlap.
Anyone knows how to do that?

Android - Ghost Click - ModalView over ListView

Kendo Mobile version - 2012.3.1315. I am having issues on native Android devices with click events. I have a ListView and register to its data-click event. I then show a ModalView over the ListView. When I click the Close button of the ModalView, the underlying ListView click event fires as well (ghost click). I cannot recreate this scenario in the Icenium simulator. It only occurs on native devices.

Edit: I've also tested this scenario on 2013.1.703 and the same behavior occurs.

<div id="modalview-additional-info" style="width: 80%; height: 70%;">

<div data-role="header">

<div data-role="navbar">

<span>Info</span>

<a data-click="closeModalViewAdditionalInfo" data-role="button" data-align="right">Close</a>

</div>

<div data-role="scroller">

<p id="additionalInfo"></p>

</div>

<ul data-role="listview" data-type="group" data-click="equipmentListViewClick">

...

</ul>

TreeView checkboxes with remote hierarchical datasource MVC - Country / Region

How can I create a treeview layout using checkboxes similar to the example below:

[ ] Country A
[ ] Region A
[ ] Territory 1
[X] Region B
[X] Territory 2
[X] Territory 7
[ ] Country B
[ ] Region C
[ ] Territory 3
[ ] Territory 4

I am using the MVC helpers and would like to load the data in one call to the controller i.e. NO on-demand loading.

I've been trying to use the following example: http://demos.kendoui.com/web/treeview/remote-data.html - but I
don't understand how I should construct the JSON object to include children etc.

Similar post here? - http://www.kendoui.com/forums/kendo-ui-framework/hierarchical-data-source/good-way-to-populate-entire-hierarchical-datasource-with-one-data-call.aspx

Any examples would be great.

Thanks,
Beau

Example: Treeview with highlight search term

Hello All:

I wrote fiddle http://jsfiddle.net/RichardAD/QfDd9/ to demonstrate how a portion of a node text value can be highlighted when it matches a search term. Could also be tweaked to hide non-matching nodes.

I'm looking for feedback on the technique and improvements.

Thanks,
Richard

Dynamically defining the tooltip format

Hi, I'm trying to generate a ListView with a sparkline for each item. Each sparkline is associated with a metric that is provided by data source. Each metric has the information about the service that provides its data and the datatype. I'm using the datatype to define the format of the tooltip. However, the tooltip format function is bind only when each value of the series and not in the sparkline definitio. So, it uses the information of the last metric for all the sparklines. How I can use the correct datatype to set the tooltip?

This is my code:

01.createChart: function (e) {

02. var list = e.sender;

03. var data = list.dataSource.data();

04. for (var i = 0; i < data.length; i++) {

05. var item = list.wrapper.find("[data-uid='" + data[i].uid + "']");

06. var chart = item.find(".chart");

07. var metric = data[i];

08. this.metrics[data[i].uid] = metric.MetricType;

09. chart.kendoSparkline({

10. type: "column",

11. dataSource: new kendo.data.DataSource({

12. transport: {

13. read: {

14. url: metric.MonthService,

15. dataType: "json"

16. },

17. parameterMap: function (options, operation) {

18. if (operation === "read") {

19. options.hotelId = 2; // _model.get('hotelId');

20. options.year = 2013; //_model.get('date').getYear() + 1900;

21. options.month = 7; //_model.get('date').getMonth() + 1;

22. return options;

23. }

24. return options;

25. }

26. }

27. }),

28. series: [{

29. type: 'column',

30. field: metric.MonthValue,

31. color: '#ff0000',

32. negativeColor: '#0099ff',

33. metricType: metric.MetricType // Hack? or Extension

34. }],

35. tooltip: {

36. format: function () {

37. switch (metric.MetricType) {

38. case 0: // Graduacion

39. return "{0:N2}";

40. break;

41. case 1: // Cantidad

42. return "{0:N0}";

43. break;

44. case 2: // Moneda

45. return "{0:C2}";

46. break;

47. case 3: // Indice

48. return "{0:N2}";

49. break;

50. case 4: // Porcentaje

51. return "{0:P2}";

52. break;

53. case 5: //Clasificacion

54. return "{0}";

55. break;

56. }

57. },

58. visible: true,

59. shared: false

60. }

61. });

62. }

In line 14 I set the url of the service based on the metric information. An in line 37 I trying to use the same approach for defining the tooltip but doesn't work. The last metric info is used for all the tooltips.

Thanks in advance.
