get()/set()

This is from your "Getting started" page:

<div id="view">

<!-- The value of the INPUT element is bound to the "firstName" field of the View-Model.

When the value changes so will the "firstName" field and vice versa. -->

<label>First Name:<input data-bind="value: firstName" /></label>

<!-- The value of the INPUT element is bound to the "lastName" field of the View-Model.

When the value changes so will the "lastName" field and vice versa. -->

<label>Last Name:<input data-bind="value: lastName" /></label>

<!-- The click event of the BUTTON element is bound to the "displayGreeting" method of the View-Model.

When the user clicks the button the "displayGreeting" method will be invoked. -->

<button data-bind="click: displayGreeting">Display Greeting</button>

</div>

<script>

// View-Model

var viewModel = {

firstName: "John",

lastName: "Doe",

displayGreeting: function() {

// Get the current values of "firstName" and "lastName"

var firstName = this.get("firstName");

var lastName = this.get("lastName");

alert("Hello, " + firstName + " " + lastName + "!!!");

}

};

// Bind the View to the View-Model

kendo.bind($("#view"), viewModel);

</script>

You can actually condense these lines:

// Get the current values of "firstName" and "lastName"

var firstName = this.get("firstName");

var lastName = this.get("lastName");

alert("Hello, " + firstName + " " + lastName + "!!!");

into a single line which uses the properties directly instead of calling "get()" and assigning it to a local variable, first. In other words, this works:

alert("Hello, " + this.firstName + " " + this.lastName + "!!!");

That makes a lot of sense because we should be able to directly use the local properties. However, this does not work if you wanted to clear the input:

this.firstName = '';

You have to use this, instead:

this.set("firstName", '');

which seems strange. So, my questions are:

1) Is there a reason why you didn't directly use the properties (e.g. "this.firstName" instead of "var firstName = this.get('firstName');") in the demo? Is there a downside to doing it that way?
2) Is the fact that we can't "set" local properties directly (as we can "get" them) a bug/oversight?

Thanks.

Data Export after filters are applied

I have a kendo grid that is attached to a datasource. Users are able to apply filters on the grid and I'm wondering if there is a way to extract the data after the filters are applied?

The reason for this is that I can then send the filtered data to the server and export to csv/excel. Currently my export works, but doesn't take into account any filters. It exports all the data from the grid.

Thanks!

Initial loading indicator when loading grid

When the grid is initilalised, and waiting for its first data set to be returned from the remote datasource, the loading indicator doesn't show, which makes it unclear to the user that data is being loaded...

Is this a bug, or is there a way I can change this behaviour?

It works perfectly fine when going to another page; then we have a nice loading indicator when data is being fetched...

pageable: { pageSizes: true }

Hi, I question whether pageable parameter: {pageSizes: true} it is possible to give individual values? Currently there are 5, 10, 20, and I need 25, 50, 100. I searched the documentation, but for now there is no information about this parameter.

Array Pop

Is there no easy way to pop an item from an array?

Take this code for example"

<div id="kendo-bound-resourcelist" data-bind="visible: isVisible" >

<div data-role="grid" data-sortable="true" data-bind="source: items" data-columns='["Title", "PMID", "TypeOfMaterial",""]' data-row-template="row-template"></div>

</div>

<script id="row-template" type="text/x-kendo-template">

<tr class="k-grid-edit-row">

<td>

<span data-bind="text: Title"></span>

</td>

<td>

<span data-bind="text: PMID"></span>

</td>

<td>

<span data-bind="text: TypeOfMaterial[0]"></span>

</td>

<td>

<input type="button" data-bind="click: deleteItem" value="Delete" />

</td>

</tr>

</script>

Ok so on click we call the delete in the model

this._viewModel = kendo.observable({

items: [],

isVisible: function () {

return this.get("items").length > 0 ? true : false;

},

deleteItem: function (resource) {

this.get("items").pop(resource);

}

});

So why doesn't this work? :/ It's just popping off the last item in the array instead of the item I'm giving it.

I've tried doing things like this, but end up at the same result

var deletedId = resource.data.Id;

var items = this.get("items");

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

if (items[i].Id === deletedId) {

this.get("items").pop(items[i]);

}

What am I doing wrong?
