Questions on Kendo UI for jQuery Forum

I have the requirement that ComboBoxes need to load their data lazily, which i did by setting the datasource to server-bound data and configure the combobox to autoBind=false. So the combobox fetches the data only when opened for the first time. However, the initially selected value is known in advance, so i create the DOM element for the combobox accordingly (meaning the <select> already has an <option> for the initially selected item).

But: In some cases, i need to "revert" a combobox that has already fetched the data to the state before fetching, i.e. when i open the combobox after "reverting" it, it should behave like it was never opened before, which means it (re)fetches the data.

See this jsbin for details: http://jsbin.com/wetarafo/1/edit

Is there any way to do this?

Navigate with history.replaceState()

When Kendo detects support for history.pushState(), it uses it to store history on each navigate(). I want to exclude some of these navigate() calls from this login because I don't want user to be able to back into this particular view. This can be achieved with history.replaceState(), does Kendo provide a way to do replaceState() instead on pushState()?

Possible bug in dependent method login

If I follow http://docs.telerik.com/kendo-ui/getting-started/framework/mvvm/observableobject#creating-a-dependent-method and create a dependent method on my observable object, I can not use other dependent methods within its logic. This forces me to duplicate logic.

Example:

var data = kendo.observable({

listing: {

price: 12300

},

formatted: {

total_due: function() {

// this works

return kendo.toString((this.parent().get("listing.price")* this.parent().get("quantity"))/100, "c");

// this crashes with an error

return kendo.toString(this.parent().get("total_due")/100, "c");

}

},

quantity: 1,

total_due: function() {

return this.get("listing.price")* this.get("quantity")

}

})

Grid : DateTime Format and Grouping doesn't work

Hi,

I have a field in my grid containing a DateTime. I'm displaying only the yyyy/mm/dd, but the value behind is also containing the time.

With the Format I have no problem to display the date correctly, but when i'm grouping on this column, the grouping is using the data (With the time) and not the displayed value (yyyy/mm/dd)

So my question is : Can I set the grouping to use the DisplayedValue and not the "real" data?

Here is how I format my column :
.Bound(p => p.CreationDate).Format("{0:" + CultureInfo.CurrentCulture.DateTimeFormat.ShortDatePattern + "}");

Thanks

Reorder elements in the Grid Pager

Hi,
Is there a way to reorder elements in the pager.
For example the "message" (i.e. "1 - 10 of 2000 items") should be on the left; pageSizes, page buttons, and page input all floated to the right.
I found how to configure each element in http://docs.telerik.com/kendo-ui/api/web/grid#configuration-pageable, but don't see a way to control the order or use a template. If there is a way to do this via jquery, would you please provide an example.
Thanks!

knockout support

Hi,
is any plan for real support Knockoutjs or angular like your competitors eg Wijmo or Syncfusion ?
I'm trying to do something using knockout-kendo library but it is not working fine (sorting is not working when I'm using custom headers).
Telerik MVVM is not what is standard in many companies (i'm working on contracts) and apart from it is not supported by other library like breeze.
But the most important thing is that I'm subscribing devcraft just for support because I'm using only kendo Web and if i'm using knockout I'm loosing support.
I'm very sad because I like Kendo UI but it is very difficult working with it if you are working on more complex project.
Thanks.

Problems recognizing selectable in listview

I am trying to set a listview selectable, but that gives me an error.
My code:

var lv = $('#lwTest');

lv.kendoListView(

{

selectable: "single",

template: "<li><span class='email'>${email}</span> <span style='font-size: 80%; font-weight: bold'>${role}</span></li>",

dataSource: the_items

});

This gives me the following in firebug:

TypeError: n.ui.Selectable is not a constructor

If I omit selectable, the listview will initialize correctly, but will of course not have selectable items.

Databinding issues

Hi,

I have a simple login screen where user enters any username and any password... The entered values are stored in localStorage using setItem.

// Set local storage values

localStorage.setItem("Username", username);

localStorage.setItem("Password", password);

localStorage.setItem("DisplayName", "Woot Woot - " + username );

utils.navigate("#menu-view");

I then navigate to a different screen which has a ViewModel and a single property that reads the value from localStorage and displays it on the screen.

define(["kendo"], function (kendo) {

return {

init: function (initEvt) {},

beforeShow: function (beforeShowEvt) {},

show: function (showEvt) { },

viewModel: kendo.observable({

displayName: localStorage.getItem("DisplayName")

})

};

});

I can see from debugger that the values are correctly being stored when I click sign in, but sometimes (most times infact) when I navigate to the second screen the values are not shown, or an old value is shown.... It is kind of like I need to refresh the datamodel from localStorage when I init, beforeShow, or show the second view...

Can anyone shed any light on what I am missing... sample app developed in VS extension and available if required, but i cant attach cos it is > 2mb and not an image!!

Many thanks

Value Binding with remote data source

Hi everybody,

i am starting to use kendo ui mobile and i have a problem.
I am trying to link a html select to a remote datasource.

my html:
        <select id="fromto-activity" data-value-field="id" data-text-field="name" data-bind="source: activitiesDataSource, value: selectedActivity"></select>

my javascript:
        var viewModel = kendo.observable({
           activitiesDataSource:new kendo.data.DataSource({
                transport: {
                    read: {
                        url: WEB_SERVICE_URL + "activities",
                        dataType: "json"
                    }
                }
           }),
            selectedActivity: "2"
       });

        kendo.bind($("#fromto-activity"), viewModel);

the service returns json:
        [{"id":1,"name":"Name1"},{"id":2,"name":"Name2"}]

The select element is filled with the data of the service.

The Problem is, that the value selectedActivity isn't bound to the select element.

When I add data-role="dropdownlist", everything works fine. But I don't want that, because I want to develop a mobile app and want to use the html select element with his styling.

When I don't use a remote data source, then everything works fine too. For example with this datasource:
     activitiesDataSource:[
    { id: 1, name: "Name1" },
          { id: 2, name: "Name2" },
          { id: 3, name: "Name3" }];

Could anybody tell me, what's mistake?
                              ],
