Hi,

This should be a minimal test case for TreeView reading its data from json file. Currently, we are testing it localy, using Internet Information server.
This is how we invoke the page:

http://localhost/cbp/index.html#/bb

In Chrome, F5 does not reload TreeView, Ctrl+F5 does. In Internet Explorer, reload displays TreeView for a fraction of a second and then its erased.

What problems do you see in this source and how should it be resolved?

Thanks,
Ivan

Hi,
We have angularjs - kendo ui based solution. In the template kendo tree is defined with k-options param set to angular controller variable.
Please see attached :
1. bulletinBoard.tpl.html - template where kendo tree is defined
2. bulletinBoard.js - controller

Inside controller we have defined factory for communication with web api in order to retrieve asynchronously json response.

In the LogConsole.png, I have pasted just for the reference that valid json is returned and unwrapped in the controller by calling .then(function(data)... call.

However tree is not populated with the fetched data.
Please advice what are we doing wrong?

We are new to Angular, Kendo and spent many hours trying to resolve this issue.

Thanks in advance,
Sincerely
Ivan

Hello,

When I remove an item from an array using splice, as per your examples, it appears that two items are being removed from the array rather than just one.
I've created an example below:

http://trykendoui.telerik.com/iBec

It seems to be caused by using the 'set' command against the array:


Am I using the set command in the wrong way?

Thanks.

Environment:
VS2010 - MVC4 Web Project
Server 2008 R2
IE 8 / FF 10
Telerik UI for ASP.NET MVC 2014.1 318
jQuery 1.9.0

I am not able to get a reference using the element.data("kendoGrid") syntax.  Every time I hit that code, my variable is undefined.

Can someone please point me to what I'm missing?

Hello everyone!

I'm new with Phonegap and Kendo!
I look for a solution for several hours and nerver found it, so I need your  precious help!

I  have a listview-link and when I click on an item, I call a function who use "app.navigate" to redirect to an another page, but I want to know if is it possible to send datas to this another page? and how to do that?

Maybe I should use an another solution than app.navigate? 

thank you in advance.

I have a grid I'd like to populate that uses a viewmodel that has a datasource with a REST url that has parameters for filtering the data.  I'm trying to set the url parameters, but I'm unable to get at them from the nested datasource.

How can I make the nestd url dynamically reflect the changes in the parent observable?  My viewmodel is below, and any help is appreciated!

Thanks, Dennis

How can I bind a select element to a kendo.data.DataSource? I know a select element can bind to an array of JavaScript objects but I would like to use the kendo.data.DataSource instead. I've been following the example in the demo here although it doesn't use a DataSource.

The error message I get in the console of the simulator is "Uncaught ReferenceError: DEP_ID is not defined"

Some example code, that shows what I'm trying to do and returns the above error, is below. Note that I am using Graphite and have included the SQLite plugin in my project.

<div data-role="view" id="tabstrip-Employees" data-title="Employees" data-model="employeeVM">
    Department
    <select data-bind="source: departmentSource"
        data-value-field="DEP_ID" data-text-field="DEP_Name">
    </select>
</div>

var employeeVM = kendo.observable({
    departmentSource: new kendo.data.DataSource({
        transport: {
            read: function(options){
                data.db.transaction(function(tx) {
                    tx.executeSql("SELECT DEP_ID, DEP_Name FROM Department", [], 
                        function (tx, rs) {
                            options.success(data.toArray(rs));
                        }, 
                        data.onError);
                });
            }
        }
    });
});

var data = {
    db: null,
    
    init: function() {
        data.openDb();
        data.createTables();
    },
    
    openDb: function() {
        if(window.sqlitePlugin !== undefined) {
            data.db = window.sqlitePlugin.openDatabase("SuperStore");
        } else {
            // For debugging in simulator fallback to native SQL Lite
            console.log("Use built in SQL Lite");
            data.db = window.openDatabase("SuperStore", "1.0", "SuperStore", 200000);
        }
    },
    
    createTables: function() {
        data.db.transaction(function(tx) {
            tx.executeSql("CREATE TABLE IF NOT EXISTS [Department]( \
                [DEP_ID] INTEGER PRIMARY KEY ASC, \
                [DEP_Name] TEXT NULL \
            )", []);
            tx.executeSql("DELETE FROM Department");
            tx.executeSql("INSERT INTO Department(DEP_ID, DEP_Name) VALUES (?,?)",
                [1, "Department 1"]);
            tx.executeSql("INSERT INTO Department(DEP_ID, DEP_Name) VALUES (?,?)",
                [2, "Department 2"]);
            tx.executeSql("INSERT INTO Department(DEP_ID, DEP_Name) VALUES (?,?)",
                [3, "Department 3"]);
        }, data.onError);
    },
    
    toArray: function(result) {
        var length = result.rows.length;
        var data = new Array(length);
        for (var i = 0; i < length; i++) {
            data[i] = result.rows.item(i);
        }
        return data;
    },
    
    onError: function(tx, e) {
        if(e !== undefined){
            console.log("Error: " + e.message);
        }
        else if(tx !== undefined){
            console.log("Error: " + tx.message);
        }
    }    
};

// Wait for PhoneGap to load
document.addEventListener("deviceready", onDeviceReady, false);

// PhoneGap is ready
function onDeviceReady() {

Dear Support Team,

My Company bought Kendo UI Complete version. What I would like to do is, I want to create as Kendo UI Mobile Project and want to have default template for mobile from Kendo UI at the Visual Studio 2012 new Project Dialog. How can I install Kendo UI to Visual Studio 2012?

I also install ICENIUM demo version. With this, I can see project Template at the Visual Studio. Please let me know without using ICENIUM, is there a way to get project template if I only have kendo UI complete.


Thanks & Regards,

Hi,

How can we know that the selected TreeView Node is having the Child Nodes or Not.

Help is required on this.

Satish.N

I have a stock chart, and when zoomed with the mouse wheel it goes deeper and deeper, all the way to hours and minutes.

I want to have the zoom limited to seven days. 

Is this possible?
