Compare Old and New Values After Grid Refresh

I have a Grid instance that is being refreshed every X seconds and would like to compare the new data (remote) with the existing data, which then affect how the data is displayed within the grid. I have looked through the documentation and the forums but can't seem to find a way to compare the two. The "change" config seems to be for only inline editing... but maybe I am wrong. Any help/links would be appreciated. Here is an example of what is going on here (I would like to compare the values returned for "rate" and "high_rate"):

// KendoUI grid

var kgrid = $("#rate_grid").kendoGrid({

dataSource: {

data: get_rates(),

pageSize: 100

},

height: 360,

groupable: false,

scrollable: {

virtual: true

},

sortable: true,

pageable: false,

columns: [ {

field: "rate_name",

width: '65px',

title: "Name"

} , {

field: "rate",

title: "Rate"

} , {

field: "high_rate",

title: "High"

}],

rowTemplate: kendo.template($("#rowTemplate").html()),

dataBound: onDataBound

});

setInterval( function() {

// if KendoUI grid instance, update it

if (typeof kgrid !== "undefined")

{

$('#rates_load small').text();

var re_grid = $("#rate_grid").data("kendoGrid");

var new_grid_data = get_rates();

re_grid.dataSource.data(new_grid_data);

re_grid.refresh();

}

}, 5000);

Unable to bind TabStrip to DataSource

Hi all.

I've faced to the problem with TabStrip and DataSource. After binding TabStrip to some simple datasource, it displays nothing, but if I bind these data to the ComboBox - it works great. Here is the code:

<div id="variantTabs"></div>

<div id="comboBox"></div>

<script src="http://code.jquery.com/jquery-1.7.1.min.js" type="text/javascript"></script>

<script src="kendoUI/js/kendo.all.js" type="text/javascript"></script>

<script type="text/javascript">

function Variant(_name,_id,_content){

this.text=_name;

this.id=_id;

this.content=_content;

}

function VariantsViewModel(){

var VariantsList=[

new Variant("first","1",""),

new Variant("second","2",""),

new Variant("third","3","")

];

var localDataSource = new kendo.data.DataSource({data: VariantsList});

$("#variantTabs").kendoTabStrip({

dataSource:localDataSource

});

$("#comboBox").kendoComboBox({

index: 0,

dataTextField: "text",

dataValueField: "id",

dataSource:localDataSource

});

}

$(function(){VariantsViewModel();});

</script>

Any help would be appreciated.
Thanks.

For the above code, I cant get the grid rendered in FIrefox (10.0) till the time I comment out the sortable attribute. Its working fine in IE (7 to 9) But I want my grid to be rendered with the sortable attribute in addition to allowunsort attribute. Can you guide me how can I get the needed functionality?

Thanks & Regards,

Using save event from custom toolbar control

I have created a grid and I have needed to use a template to create the toolbar. I want to be able to batch edit then save back to the server.

If I weren't using a template I could simply use

  toolbar: ["create", "save", "cancel"],

To do what I need, however I need the template as I have a dropdown box in the toolbar and some other html.

How do I tap into these events from a control inside my custom toolbar?

Any help would be great!

Ajax call and kendo data source together

Hello
     I have a requirement where I ll do a $.ajax call and then store the ajax call response to a kendo datasource...like below
   $.ajax({
                url: url,
                type: 'POST',
                contentType: 'application/json',
                dataType: 'json',
                success: function (responsedatas) {
                     ///I got datas here..If i put debugger im able to see the datas
                     var KendoSource = new kendo.data.DataSource({ data: responsedatas});
                      $("#grid").kendoGrid({
                    dataSource: {
                        data: KendoSource
                    },
                    height: 360,
                    groupable: false,
                    scrollable: false,
                    sortable: false,
                    pageable: false,
                    columns: [{
                        field: "ContactID",

                        title: "ContactID"
                    }]
                });
                }
