Name value has been added to input

By adding the name value to the input of the this combobox means that it now gets submitted when the form is submitted, this now breaks all my data saves as they validate incomming data against the my model and obviously the input names (elemntName_input) which is now part of kenod, is not part of my model.

is there an option to change turn this off?

Using kendoui to get and save JSON objects from/tolocal file

I am pretty New to Javascript and jQuery.

I am now just learning to build User Interface and was checking out KendoUI. I must say its amazing.

I want to have data in a local file on my computer. Access the data and show it in grid/table.

I want to be able to edit and save the data back to the local file using the user interface in the browser.

I am looking at : http://demos.kendoui.com/web/grid/editing.html

Looking at the source, the data is obtained/saved from/to a remote server:

`<script>`

            `$(document).ready(function () {`

                `var crudServiceBaseUrl = "http://demos.kendoui.com/service",`

                    `dataSource = new kendo.data.DataSource({`

                        `transport: {`

                            `read: {`

                                `url: crudServiceBaseUrl + "/Products",`

                                `dataType: "jsonp"`

                            `},`

                            `update: {`

                                `url: crudServiceBaseUrl + "/Products/Update",`

                                `dataType: "jsonp"`

                            `},`

                            `destroy: {`

                                `url: crudServiceBaseUrl + "/Products/Destroy",`

                                `dataType: "jsonp"`

                            `},`

                            `create: {`

                                `url: crudServiceBaseUrl + "/Products/Create",`

                                `dataType: "jsonp"`

                            `},`

                            `parameterMap: function(options, operation) {`

                                `if (operation !== "read" && options.models) {`

                                    `return {models: kendo.stringify(options.models)};`

                                `}`

                            `}`

                        `},`

                        `batch: true,`

                        `pageSize: 30,`

                        `schema: {`

                            `model: {`

                                `id: "ProductID",`

                                    `ProductName: { validation: { required: true } },`

                                    `UnitPrice: { type: "number", validation: { required: true, min: 1} },`

                                    `Discontinued: { type: "boolean" },`

                    `toolbar: ["create", "save", "cancel"],`

                    `columns: [`

                        `"ProductName",`

                        `{ field: "UnitPrice", title: "Unit Price", format: "{0:c}", width: 150 },`

                        `{ field: "UnitsInStock", title: "Units In Stock", width: 150 },`

                        `{ field: "Discontinued", width: 100 },`

                        `{ command: "destroy", title: " ", width: 110 }],`

                    `editable: true`

                `});`

            `});`

        `</script>`

Any help with a working example shall be hight appreciated.

Selecting a treeview item by it's data properties

Hi folks,

I'm using a treeview from a HierarchicalDataSource and wanted to be able to get the element from the treeview if it matched all the properties that I specified. My initial data looked something like this:

[{

id:'2022',

text:'Folder1',

items: [{

id:'3202',

text:'Sub-Folder1'

}, {

id:'1234',

text:'Sub-Folder2',

moo: true

}]

I wanted to be able to get the list item element (<li>) for any particular item so I built a function to do it and thought I'd share. You can use my function like this (in this example I want to get the element for the item with the id '3202':

var liElement = $('#treeView').data('kendoTreeView').search({id:'3202'});

You can also search on multiple properties:

var liElement = $('#treeView').data('kendoTreeView').search({id:'1234', moo: true});

To enable this functionality, after creating a treeview with a HierarchicalDataSource, add this code (assumes your treeview element is #treeView - change as required):

$("#scenegraph-treeview").data('kendoTreeView').search = function (json, source) {

if (json !== undefined) {

var data = source || this.dataSource,

child, item, i, k, match, allMatched;

// If the data has the properties we need

if (data && data._data) {

child = data._data;

// If the array has items

if (child.length) {

// Loop the array items

for (i = 0; i < child.length; i++) {

item = child[i];

console.log('Checking child ' + i + ' id ' + item.id);

// Check each json property against the current item's properties

// and if they all match, grab the tree item based on it's UID

allMatched = true;

for (k in json) {

if (json.hasOwnProperty(k)) {

if (item[k] !== json[k]) {

// The item doesn't have all the properties

// that the json object does

allMatched = false;

break;

}

if (allMatched) {

// We've found a match, grab the tree item from the UID and return it

return this.findByUid(item.uid);

} else {

// We didn't find what we were looking for so search the children

if (item.children) {

match = this.search(json, item.children);

if (match) {

return match;

}

};

Hope this helps someone out!

Form input fields missing

Hi, the whole form was working properly before, and after I decorated some input fields of the form with kendo, in the action, I var_dump the form, those kendo inputs are missing and everything else is all good.

Any idea guys ? Please help me to save my hair, cheers.

I also checked with other UI plugins, it's all good.

Is this cause by the version I chose, open oource one ?

Bind to Single Record

I'm in the midst of writing a single page application with routes. The way the application functions is:

DataSource with list of items is bound to a Kendo Grid
User clicks an item on the Grid and is taken to a new route which contains the ID of the item the user selected. Example: www.mydomain.com/#itemID=1
This ID is used in a DataSource to refresh the item the user chose. This is also done in case the user bookmarks the specific route. In such an event the Grid can be bypassed.

The binding of the Grid works great and I'm able to capture the ID of the chosen item and redirect to my new route. I'm also able to create a new datasource with the ID of the item selected and return data from the server.

Here's where I'm stuck. I'm trying to bind the returned record to HTML controls using an MVVM pattern, but it seems the Kendo binding context assumes that DataSource is a collection (where in my case it's a single record). What is the correct approach for this? Is there a way to bind controls in a DIV to a single record in a DataSource?

Binding Kendo WIndow and Input with type Password

I am trying to implement a MVVM pattern for my website's login function.

The site returns with status code 401 when authentication fails. The goal would be to:

Update my view model to indicate that the user is not authenticated. Example: viewModel.set("authenticated", false)
When authenticated is false, display a Kendo window with the username/password prompt
Then the user presses submit within this window, fire my login method

Everything works except I am having the following problems:

I can't find a way to bind the open/close state of the Kendo window (my login window) to the authenticated property of my viewModel
When I bind to the input of type password, it seems to be one-way. I am able to get the password the user typed in and pass this up to my web method, but during the login function I clear the password viewModel.set("password", "") but the input control does not update. If I change it to a regular input with type text it seems to work.
