I have 4 in TabStrip, When a tab is activated, I want to zoom the icon of the Tab. 

<footer data-role="footer">
        <div data-role="tabstrip" data-id="tabStrip">
            <a href="#home" id="x" data-icon="home">Home</a>
            <a href="#xxx" id="a" data-icon="login">Login</a>
    <a href="#xxx" id="b" data-icon="login">xxxx</a>
            <a href="#xxx" id="c" data-icon="login">xxx</a>
        </div>
 </footer>

var tabStrip = $("#tabStrip").data("kendoMobileTabStrip");

tabStrip.currentItem();// returns undefined for me.
 And is there possibility to scroll the TabStrip?

I have noticed an error related to column re-sizing when using remote virtualization. During re-size I am noticing a gap appearing in the grid (see screen shot). I have also attached a sample project.
I initially thought this was due to hidden columns in the grid, but it appears to be related to scroll with remote virtualization.
The issue goes away if I disable the remote scroll/virtualization...

Browser: IE 8.0

Thanks

I've been struggling to find a better way to filter an ObservableArray to a subset of values.  At first glance it seems like this should be easy.  Simply add a function to the view model to create an array with only those items I want and then set the binding source to that function.

Here's an example:

<ul class="items" data-template="row-template" data-bind="source: itemsFiltered"></ul>

 itemsFiltered : function () {
       var iFlt = [];
       var iCurr = this.get("Items");
       for (var i = 0; i < iCurr.length; i++) {
           if (iCurr[i].get("State") != "CA") { //Ex: filter out all items in CA
               iFlt.push(iCurr[i]);
           }
       }
       return iFlt;
   }

This sort of works, but I'm getting some strange Focus and Blur behaviors in IE when binding to the Filter function.  These behaviors go away if I bind directly to the array.

I can't help but think that IE doesn't like the fact that I'm replacing the entire array each time the view model changes.  I know KnockOut has a utility function to handle filtering like this (ko.utils.arrayFilter), and such a function is more ideal than returning a new array.

Does Kendo MVVM contain an equivalent to ko.utils.arrayFilter?  If so, what is it?  If not, I'd like to recommend adding such a function.  Ideally the binding features of kendo should call always call a filter function (default implementation would return a value of true) when evaluating the binding of each item.

Is there another way to accomplish filtering in kendo MVVM?  I know I could theoretically add an binding for invisible and point to a function that evaluates whether or not to display the item, but this is only a partial solution as the item itself would still be in the DOM.

In v2012.3.1401's kendo.window.js line 795. Should be using $ instead of global `jQuery`

I am looking for a way to structure textual content within a cell (e.g. <li> bullets or <p> or <div> or <br>).  

This would be one cell:
Monday Menu
Breakfast: eggs&bacon
Lunch: bean&bacon soup
Dinner:bacon-barded duck


The following is just one idea. Maybe there is a better way:

Assuming the fields:

          MondayBreakfast,MondayLunch,MondayDinner, TuesdayBreakfast, TuesdayLunch, TuesdayDinner ... etcetera

is this a legal cell template?

                               
                    <td>   <div>${MondayBreakfast}</div><div>${MondayLunch}</div><div>${MondayDinner}</div>     </td>                       
                   <td>   <div>${TuesdayBreakfast}</div><div>${TuesdayLunch}</div><div>${TuesdayDinner}</div>  </td>  

If yes, how would the columns attributes (title literal, sortable, groupable, etc) be defined in the grid configuration?
.
,schema: {
                model: {
                    fields: {
                        MondayBreakfast: { type: "string" },
                        MondayLunch: { type: "string" },
                        MondayDinner: { type: "string" },
                       TuesdayBreakfast: { type: "string" },
                       TuesdayLunch: { type: "string" },
                        TuesdayDinner: { type: "string" },
                       WednesdayBreakfast: { type: "string" },
                       WednesdayLunch: { type: "string" }
                         etc etc
                    }
                }
            }
        },
 columns: [
    { field: ??  , groupable: false, sortable: false, title: "Monday Menu", width: 150 },
    { field: ?? , groupable: false, sortable: false, title: "Tuesday Menu", width: 150 },
   
]
.

Hi. when I use the newest v2012.3.1315's splitter (kendo.web.min.js) in ie9's compatibility view, the ie9 become very slow when I just mouse mouse on the page. it's ok in  ie9's normal view and chrome.
when I replace it whith the v2012.3.1114's splitter(kendo.web.min.js), then all it'is ok.
So the newest v2012.3.1315 kendoui maybe has Serious performance problems.
Thanks!

Hello - This question is regarding the usage of kendo.init() method in a mobile app. I am trying to inject some kendo ui markup using an ajax call, *after* the kendo app has been instantiated. For brevity's sake, I am showing some oversimplified code, see below:

<div id="container" data-role="content">
<ul data-role="listview" id="mylist">
<li> item 1 </li>
<li> item 2 </li>
<li> item 3  </li>
<li> item 4  </li>
</ul>
</div>    


Once the ajax call has returned and the above code has been appended to the kendo view, I am doing the following:

kendo.init($("#container");

This, however doesn't seem to work - the list looks like an HTML list and not a Kendo listview widget. On the other hand, if I individually initialize the listview widget using $("#mylist").kendoMobileListView(), it works.

Could you provide an explanation to this? 

I am using the init() method as described in the docs (http://docs.kendoui.com/getting-started/data-attribute-initialization). I am also curious to know why the init() method is not in the API reference.

Thanks,
Petyo

Calling the jsonp response but receiving Error : jQuery18207158344800118357_1359997121430 was not called. can some one let me know how to fix this ? Appreciate your help. Below is the client code :

<script>
        function mobileListViewPullToRefresh() {
        var dataSource = new kendo.data.DataSource({
serverPaging: true,
    pageSize: 2,
type: "odata",
error: function(e) {
console.log("Error " + e);
alert(e.errorThrown);
   },
    transport: {
    read: {
                   url: "http://localhost:50675/movie/GetAll", 
                       dataType: "jsonp"
                       },
                       parameterMap: function(options) {
            alert("Inside parameterMap")
            alert(JSON.stringify(options, null, 4));
                       return {
                           q: "javascript",
                           page: options.page,
                           rpp: options.pageSize,
                       };
                      }
                 },
                 schema: {
        errors: function(response) {
       return response.errors;
   },
data: function(data) {
                    if (data.movieList.length == 0) {
    return [];
    }
return data.movieList;
       },
       total: function(data) {
        alert(data.movieList.length);
                           return data.movieList.length;
                       }
              }
});

$("#localListView").kendoMobileListView({
           dataSource: dataSource,
           pullToRefresh: true,
           appendOnRefresh: true,
           template: $("#categories-template").html(),
           pullParameters: function(item) {
            alert("Inside pullParameters")
            alert(item.length);
            alert(JSON.stringify(item, null, 4));
               return {
                   page: 1
                };
            }
       });
       };
       
       window.kendoMobileApplication = new kendo.mobile.Application(document.body);
    </script>

When checked in Chrome developer tools the response is successfully received from server. Below is the jsonp response from the server :

({"movieList":[{"ID":1,"Title":"Movie","ReleaseDate":"/Date(487189800000)/","Genre":"Comedy","Price":30},{"ID":1,"Title":"Movie","ReleaseDate":"/Date(487189800000)/","Genre":"Comedy","Price":30}],"count":4})
