I’m trying to load a tree from a JSON string which is being returned from a Java action instead of having it statically inside the HTML.

The original code was like so:

<script>

$("#treeview-left, #treeview-right").kendoTreeView({

dragAndDrop: true,

dataSource: [

{ text: "Item 1", expanded: true, items: [

{ text: "Item 1.1" },

{ text: "Item 1.2" },

{ text: "Item 1.3" }

] },

{ text: "Item 2", items: [

{ text: "Item 2.1" },

{ text: "Item 2.2" },

{ text: "Item 2.3" }

] },

{ text: "Item 3" }

]

}).data("kendoTreeView");

</script>

I modified it like so:

<script>

$("#treeview-left, #treeview-right").kendoTreeView({

dragAndDrop: true,

dataSource: {

transport: {

read: {

url: "/site/GetTreeData.action",

dataType: "json"

}

}).data("kendoTreeView");

</script>

The GetTreeData.action returns the following JSON string:

[

{ text: "Item 1", expanded: true, items: [

{ text: "<a href='http://localhost:8080/site/GetEmployee.action'>clear here</a>", encoded: false },

{ text: "Item 1.2" },

{ text: "Item 1.3" }

] },

{ text: "Item 2", items: [

{ text: "Item 2.1", items: [

{ text: "Item 2.1.1" },

{ text: "Item 2.1.2" }

] },

{ text: "Item 2.2" },

{ text: "Item 2.3" }

] },

{ text: "Item 3" }

]

If I paste the previous JSON string inside the page and reload it, the tree displays just fine.

So, what am I doing wrong?

Tree View and XML Data Source

Hello,
I've been reading the existing documentation about the Treeview as well as the Hierarchical Data Source and the Data Source but I kinda lost it about the possible remote data source types that I can use with the Treeview.
Apart from json,xml is also supported right?Is it possible to bind it and view the xml file with the Treeview?
I've been trying something like:

<title>Tree View</title>

<link href="shared/styles/examples-offline.css" rel="stylesheet">

<link href="styles/kendo.common.min.css" rel="stylesheet">

<link href="styles/kendo.blueopal.min.css" rel="stylesheet">

<script src="js/jquery.min.js"></script>

<script src="js/kendo.web.min.js"></script>

<script src="shared/js/console.js"></script>

</head>

<body>

<div id="example" class="k-content">

<div id="treeview" class="demo-section"></div>

<script>

var ds = new kendo.data.DataSource({

transport: {

read: {

url:"http://localhost:8080/OnTheSpotRestfullAPI/testTree.xml"

}

},

schema: {

type: "xml",

data: "/tree/vehicles",

model: {

fields: {

car: "car/text()",

bike: "bike/text()"

}

});

$("#treeview").kendoTreeView({

dataSource: ds

});

</script>

<style scoped>

#example {

text-align: center;

}

.demo-section {

display: inline-block;

vertical-align: top;

width: 320px;

height: 300px;

text-align: left;

margin: 0 2em;

}

</style>

</div>

</body>

</html>

with the testTree.xml being:

<?xml version="1.0" encoding="UTF-8" standalone="yes"?>

<tree>

<vehicles>

<car>FM-1100</car>

<car>FM-4200</car>

<bike>FM-3100</bike>

</vehicles>

<personnel>

<client>GH-3000</client>

<vip>GH-3100</vip>

</personnel>

</tree>

but I can't seem to be able to view the tree at all..kinda lost here,can someone please point me to the right direction?

Thanks in advance

BUG: event passed to click event handler does not tell you which action button has been clicked

To reproduce:

Take the sample at http://demos.kendoui.com/mobile/actionsheet/index.html
Modify to call the same event handler

<ul data-role="actionsheet" id="inboxActions" data-open="onOpen" data-popup='{"direction": "left"}'>

<li class="km-actionsheet-title">Monday Meeting:</li>

<li><a href="#" data-action="reply">Reply</a></li>

<li><a href="#" data-action="replyAll">Reply All</a></li>

<li><a href="#" data-action="archive">Archive</a></li>

</ul>

becomes

<ul data-role="actionsheet" id="inboxActions" data-open="onOpen" data-popup='{"direction": "left"}'>

<li class="km-actionsheet-title">Monday Meeting:</li>

<li><a href="#" data-action="singleEventHandler">Reply</a></li>

<li><a href="#" data-action="singleEventHandler">Reply All</a></li>

<li><a href="#" data-action="singleEventHandler">Archive</a></li>

</ul>

Then try implementing singleEventHandler as below:

function singleEventHandler(e) {

if (<some test involving e>) {

$("#actionResult").html("Replying to message #" + e.context);

} else if (<some other test involving e>) {

$("#actionResult").html("Replying to all in message #" + e.context);

} else if (<some other test involving e>) {

$("#actionResult").html("Archiving message #" + e.context);

}

     doMoreStuff();

}

The problem is e only has two properties: target and context

target is not the button which has triggered the event but the button which has opened the action sheet, so there is no way to know which button in the action sheet has been triggered in the event handler.

If not a bug, this is in my opinion a design issue which prevents properly factoring code as the only workaround is to multiply event handlers when it is not always necessary.

How to use 2 different values on a client template?

Here is a snippet:

columns.Bound(p => p.URL).Title("Url").Visible(false);

columns.Template(p => p.TRACKINGNUMBER).ClientTemplate(

"<a href='#= URL #'>#= TRACKINGNUMBER #</a>"

).Title("Tracking Number");

The above above client template ignores the URL value and simply displays the tracking number has a regular text field.

Reference to current item in a template

Inside an MVVM bound template, how do I get access to the data item itself?

This doesn't give it to me (clearly eh) :)

<li data-bind="invisible: #= console.log(this) #">

<span>test</span>

</li>

.data("kendoDropDownList").bind("dataBound" When exactly is this supposed to run?

So frustrating.

I have a scenario not extremely complicated in which i require items in my drop-down actually be databound before selecting a default item.

So when does this databound event actually run? Inside my databound event handler i am checking the count of items in the dropdownlist and it is ZERO.

I have been trying to track down phantom errors which are a result of either this bug or a misunderstanding of the docs for 2 weeks. Can someone from telerik expand on this? from the telerik api:

dataBound

Fires when the drop-down list has received data from the data source.

Example

$("#dropdownlist").kendoDropDownList({
    dataBound: function(e) {
        // handle event
    }
});

To set after initialization

// get a reference to the dropdown list
var dropdownlist = $("#dropdownlist").data("kendoDropDownList");
// bind to the close event
dropdownlist.bind("dataBound", function(e) {
    // handle event
});

Have i misread "receive" data to mean received and bound the data? When really it's not databound? If so it would be extremely useful to have an actual databound event for the dropdownlist that was fired AFTER the items have been created.
