Kendo Grid Read Action hangs in Firefox 23.0 in Ajax Request

I am using a kendo grid (2012.2.803.340). I am binding data
on read action. It always fires correctly. But on Ajax post, it does not fire.
Other than Firefox browser, it works fine.

Don't see any events in the calendar

I seem to be having trouble displaying events in the calendar. I know that I am able to get the JSON results without an issue as I created a test page which simply echo's the JSON results. I must be missing something in the code I modified and likely it is very, very simple. On a side note, the scheduler page is loaded up within a tab strip item, but I don't think that makes a difference as I don't see the results when I connect to the page directly.

Help is much appreciated...

parameterMap to TaskViewModel transfer is broken

I have been tearing apart these blogs to find my answers since they are not yet in the (beta) documentation. My understanding is I should be able to pass data back to my ReST call by specifying what fields I want in the "parameterMap". I can see the transfer happening in the browser. Unfortunately this data is not to be found when I break in my controller code where the TaskViewModel is a parameter. Oh, and the "options.model" value is null inside the parameterMap function I have.

Am I correct in assuming this transfer of values from the parameterMap to the controller happens through the TaskViewModel? Or do I need to connect something manually? HOW DO I GET MY VALUES TO THE CONTROLLER? help please

Event binding for dropdownlist

Hi

Using MVVM techniques I have bound a dropdown list like this (this element is sitting within a Kendo UI mobile View):

<select id="treatmentTypesSelect" name="TreatmentTypes" data-role="dropdownlist" data-bind="source: TreatmentTypes, value: TreatmentTypeId, events: { click: onTreatmentTypeChange}" data-change="onTreatmentTypeChange" data-text-field="name" data-value-field="value" required required data-required-msg="Treatment Type is required"></select>

The function onTreatmentTypeChange is defined in the bound viewModel of the View.

Using the Icenium simulator the onTreatmentTypeChange event is fired and works properly, but once deployed to an android device the event is no longer raised.

I tried changing it to this:

<select id="treatmentTypesSelect" name="TreatmentTypes" data-role="dropdownlist" data-bind="source: TreatmentTypes, value: TreatmentTypeId" data-change="onTreatmentTypeChange" data-text-field="name" data-value-field="value" required required data-required-msg="Treatment Type is required"></select>
But this does not work either.

What is the correct way to bind events (in particular the change event)?

Create, Update, Destroy Not Calling WebMethods

I am using the following in my dataSource:

transport: {
read: {
contentType: "application/json; charset=utf-8",
url: "DepartmentHome.aspx/GetMembers",
dataType: "json"
},
create: {
url: "DepartmentHome.aspx/CreateMember",
type: "POST"
},
update: {
url: "DepartmentHome.aspx/EditMember",
type: "POST"
},
destroy: {
url: "DepartmentHome.aspx/DeleteMember",
type: "POST"
}
},

and in my code behind I have defined the WebMethods as such:

[WebMethod]
public static void CreateMember()
{
File.WriteAllText(@"C:\testing.txt", "This is a create.");
}

[WebMethod]
public static void EditMember()
{
File.WriteAllText(@"C:\testing.txt", "This is an update.");
}

[WebMethod]
public static void DeleteMember()
{
File.WriteAllText(@"C:\testing.txt", "This is a delete.");
}

When I create, edit, or delete a record it looks as if it has done it in the grid but it never calls the associated WebMethod.
I do see in firebug that it sends:
POST CreateMember
POST EditMember
POST DeleteMember

When I click on the associated buttons the POST data contains the parameters for that row:
FirstName: John
Id: 1
LastName: Smith

The Response back from the POST is just all the html from the page DepartmentHome.aspx.

I am using a WebMethod for read and that is working perfectly. I don't know what the difference would be?

I have attached the complete source code.

Any help would be greatly appreciated.

Scheduler data source to scheduler bind error

Dear all,
i'm new to kendo ui and i'd tried the samples of scheduler

var url = 'Service1.svc/';

var dataal;

var dataSource1 = new kendo.data.SchedulerDataSource({

API for Closing tabs?

Hello,
I've got 2 questions.
I'm using Tabstrips and i would like to let the user adding and closing them dinamically. Of course adding is supported and well documented, but i couldn't find how to do it without workaround like the one reported here:
http://www.kendoui.com/forums/kendo-ui-web/tabstrip/issues-with-dynamically-openned-tabs-and-closing-it.aspx
Is there an official way to make the tabs closable? Like "closable: true"?

Thanks in advantage.

Difficulty naming parameter on remote call

I am attempting to hit an ASP.NET MVC controller action with the Kendo Datasource from the "Autocomplete" widget. The controller looks a bit like this ..

public JsonResult Aspect(string term){

// ...

}

So I need the actual URL parameter to be called "term" from the dataSource. So given this..

$(".autocomplete").kendoAutoComplete({

dataTextField: "Name",

dataSource: {

type: "json",

transport: {

read: "/search/aspect",

data: { term: $(this).val() }

}

});

I can't seem to get this to work though.

Also, it is important to note that there are MULTIPLE auto-completes on the page with dynamic identities. So it cannot work to call a specific selector.

I have been looking for a few hours, and I'm not seeming to find a way to do this.
