How to identify if a filtering action occurred on grid

Hi Team,
I have been observing that "Change" is the event that is called either when the datasource is populated or when a filtering happens on the grid.
i would like to identify these two actions separately. How's that possible with Kendo grid !
Infact, it would be happy to not call the "Change" event on filtering.

Looking for answers on this. Thanks in advance for the replies.

How does Kendo Mobile Music Store bind the viewMode without calling dataSource.read()

I've set up a project following the KendoUI Mobile Music Store example and am having trouble binding my data to the model.

I've used the source code that is available on Github and can't seem to figure out how the DataSource is being populated without ever doing a DataSource.read();

The example I give below is my take on the example, but you could check out the artists-view.js to see the same.

Okay, the view javascript:

define(["kendo", "app/data"], function (kendo, data) {

return

viewModel: kendo.observable({

myData: data.myData

})

}

});

The relevant bits of the data class:

define(["jQuery", "kendo", "app/environment", "app/utils"], function ($, kendo, config, utils) {

var DataSourceConfig = function (url, sortField, options) {

this.transport = {

read:

{

url: url,

dataType: 'jsonp',

}

this.sort = {

field: sortField,

dir: "asc"

};

$.extend(this, options || {});

};

DataSourceConfig.prototype = {

type: "GET",

requestStart: function () { if (this.pageSize() === undefined || this.page() === 1) { utils.showLoading(); } }, //infinite scrolling has its own, less obtrusive indicator

requestEnd: function () { utils.hideLoading(); },

error: function () { utils.hideLoading(); utils.showError("There was an error loading the data from the server. Please close the app and try again."); }

};

return {

clear: function (dataSource) {

dataSource.view().splice(0, dataSource.view().length);

},

myData: new kendo.data.DataSource(new DataSourceConfig(config.myDataUrl)),

};

});

Now, this all works (sort-of) fine, but the datasource is never populated, and I feel like that is because the read() is never called. How is this working in the example?

kendo validation - error using validation

Hello,

we've got a point that our validation works, but it errors when finding the elements on the forms in order to show the messages.

as far as we see, finding (jquery .find() ) elements with a data- attribute causes a jquery Sizzle.error to be thrown.

I've attached some screenshots.

What can we do to resolve this ?

Thank you for a quick response.

Greetings

Is there anyway to block certain droppable objects

For example if I have
object1, object2 and object3
These can only be dropped in Zone1

Then I have
object4, object5 and object6
These can only be dropped in Zone2

how could I configure this?

Also I would like object 7 to be allowed to drop in either Zone1 or Zone2 but not Zone3

Grid detailTemplate definition fo dynamic list.

Hello,
could you advice me how to achieve following thing:
1. Let's assume I have list of objects with: Property1,Property2,Property3,Other
2. I can bind normaly Property1,Property2,Property3 to grid and it will be properly displayed.
3. Other property is in fact list of pairs

I would like to display all elements of that list in grid details. Could you tell me how to define such template? I know how to assign one value, e.g:

But how to bind many elements?

Best Regard

Kendo Window with .NET controls

Hello,

We are currently trying to slowly upgrade from Telerik ASP.NET controls to Kendo UI and MVC within our web forms application but ran into a problem with the Kendo Window and asp.net controls - specifically a textbox.

What is happening is whenever we have an asp:Textbox inside a div that has been transformed into a kendo window via $(".window").kendoWindow(), if we click an asp:LinkButton with an onclick event that is also within that window, the value on the textbox always comes back as "". When I remove the $(".window").kendoWindow() line, everything works fine.

We were able to reproduce this in isolation and I'm attaching the project file. Can someone help us figure out whats going on and why textboxes inside windows lose their value?

If you breakpoint inside the btnTest1_Click method after having opened the modal and typed in the Test1 text box and clicked Submit Test 1, you'll see that txtTest1 has lost its value. Why?

Showloading error when clicking/tapping screen

In my app, I have a list of people that loads the first 50 when you navigate to the view. When you first navigate, the app.showLoading() method is called. If you click or tap anywhere on the screen during the loading process it errors out saying:

Error: Uncaught TypeError: Cannot read property 'top' of undefined

Url: http://localhost:5555/assets/js/kendo.all.min.js

Line #: 46

Is there any way to prevent the kendo showLoading method from throwing this error? Should I just handle the error by hiding it instead? It seems that even though it errors, if you close the error window, all the data still has been loaded properly.
