I am doing a simple app in Kendo Mobile. I have a form that adds to a datasource when you click add. That works great. I am having trouble converting it over to use Jaydata. Here is what I have:

var alarmsViewModel = kendo.observable({

alarms: [

{ time : "13:00", note : "Note goes here", daysOfWeek : "Every Monday", onOff : "off", snooze : "off", alarmType : "ring" },

{ time : "11:30", note : "Note goes here 2", daysOfWeek : "Every Monday", onOff : "off", snooze : "off", alarmType : "ring" }

],

add: function(e) {

this.get("alarms").push({

time: this.get("time"),

note: this.get("note"),

daysOfWeek: this.get("daysOfWeek"),

onOff: this.get('onOff'),

snooze: this.get('snooze'),

alarmType: this.get('alarmType')

});

e.preventDefault();

},

onClick: function(e) {

kendoConsole.log("event :: click", e);

}

});

Now I realize I have to define the data schema, then I can just attach it to a listview like I would a normal viewmodel. How do I add to it though? My form is pretty simple just data-binding the fields like so:

<input type="time" data-bind="value:time">

All the examples in the blog post on here and on Jaydata's site all are for grids or other things that are editable.

Thanks.

[Solved] Manipulate search string

Hi,

I have a working multiselect with a remote datasource with a ton of values (1500+).
The multiselect allows my users to start typing and find the item they're looking for.

What I would like to do is manipulate/verify their search term before actually searching. Here's an example to clarify.

All items are in the same format, six numbers or letters, followed by a dash, followed by 2 numbers, example: 3Z0000-02. The length of the code before the dash is always 6 characters (letters and/or numbers); if a code has only 2 characteristics, trailing zeros are added to pad the code to 6 characters (in the example 4 zeros).

To make searching easier/faster for the users, I want to allow them to type 3Z-02 and show 3Z0000-02 as a result. I know how to manipulate the string itself, but I am looking for a hook in the MultiSelect widget where I can manipulate the search string entered by the user, before it is used for searching.

Is this possible, and if yes, which event should I use to perform this manipulation? A small example of how to manipulate a search string before filtering the datasource would be greatly appreciated.

Regards,
Rinck

Style question - keep parent style when selecting child item

I have a demo my problem online -- as you can see, I have a problem when selecting a child under Secondary Reviews or Primary Reviews.

I want the child items to remain as they are when you mouse over them or to just set text-decoration to underline. When you click on a child item, the parent should remain unchanged and the text of the child item should turn blue.

All styles are inline in the index.html page.

I know I'm missing something obvious here but just can't figure out how to change that child style without that change affecting the parent tem's style.

Thanks for any help!

grid rendering issue when located on panelBar bottom panel (initially inactive / collapsed)

I want to put together a jsBin project to demonstrate a problem I'm having with the kendo grid on a panelBar, but the problem only manifests itself when the grid contains a large amount of data, i.e. a thousand rows or more. Is there a Northwind or other URL that returns a large dataset I can use?

Here's the scenario, in the meantime.

Top panel (active panel) contains a Google map.
Bottom panel (collapsed) contains kendo grid.

User clicks on the map, and the latitude/longitude is used to fetch data from our database via AJAX.
Kendo grid is populated with the data while the bottom panel is still collapsed.
User clicks on the bottom panel to expand it and see the query results.

This works perfectly -- but only on the first query.

When the user re-opens the top map panel to click on a different location, I destroy() the existing grid, reconfigure the grid, and repopulate the grid's dataSource with the new data from the second query. Although the dataSource data object contains the full dataset from the XHR, the grid renders only the first row, and the height of the grid is truncated from 600px to 100px.

ComboBox refresh method selects an item

I have a question about some code inside the refresh() method of the ComboBox widget. Specifically, the following lines:

if (state !== STATE_FILTER && !that._fetch) {

that._selectItem();

}

In my application, the dataSource of a combobox needs to change based on the user making various choices. In this case, we use ComboBox.setDataSource() to update the combo. When the user clicks the dropdown button to open the popup, the combo does a refresh which causes the above code to run. That code selects the first item in the data, even though "suggest" and "highlightFirst" are both false. Moreover, the "change" event is not fired, so the combo shows a selection, but our application code is not notified.

Why does refresh() select an item? Shouldn't it just rebuild the options list but keep other state in the control unchanged?

Thanks,
AHG

[Solved] SPA drop down list from view template not working on re-render

Running build v2013.3.1119. The drop down list functions normally when it is first displayed, but after switching out views with a re-render of the view the drop down list becomes disabled and cannot be clicked on or accessed. I also noticed that a submit button loses its click event hander when the template is re-rendered.

Here is a jsfiddle example that replicates the issues: http://jsfiddle.net/markm1/x5q24/

I have tried different ways of creating the drop down, including using mvvm and the results are the same. Any ideas?

Here is the html:
<script id="index1" type="text/x-kendo-template">
    <select id="ddMatter1" name="ddMatter" >
        <option>Select 1...</option>
        <option value="type-1">1</option>
        <option value="type-2">2</option>
    </select>
<input id="search" name="search" type="submit" value="Search"/>
</script>
<div id="app"></div>
<br/><br/><br/>
<p>click render to break things</p>
<input id="render" type="submit" value="Render"/>

And here is the script:
var index1 = new kendo.View('index1');
$("#app").html(index1.render());
$("#ddMatter1").kendoDropDownList();
$("#search").click(function () { alert('search'); });
// render the view again to break things
$("#render").click(function () { $("#app").html(index1.render());
alert("Now the drop down does not work and the search button is no longer wired up")});

Template does not fully update

(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?

[Solved] 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?
