I have a templated list:

<script type="text/x-kendo-tmpl" id="xts-contents-detail-template">
   <div id='contents-list-sortable' data-role="listview sortable" data-template="xts-content-item-template" data-selectable="single"
        data-bind="source: contentDataSource">
   </div>
</script>

<script type="text/x-kendo-tmpl" id="xts-content-item-template">
   <div>
      <hr>
      <h5> <span data-bind='text: name'> </span> </h5>
      <span data-bind='text: description'> </span>
   </div>
</script>

Which later gets populated in Javascript:

            this.pObservableContent = kendo.observable({
                contentDataSource: new kendo.data.DataSource({
                    data: [],
                }),
            });

            let listView = new kendo.View('#xts-contents-detail-template', {
                model: this.pObservableContent,
            });

            // put the list somewhere
            let listHtml = listView.render();
            this.pView.element.find('.contents-list').html(listHtml);

            // make the list sortable
            // this.pView.element.find('#contents-list-sortable').kendoSortable({
            $('#contents-list-sortable').kendoSortable({
            });

Also, some content gets added later on:

           this.pObservableContent.contentDataSource.data(this.pReportDefinition.contents);

The user may then re-order the list.

this.pObservableContent.contentDataSource.data() does not reflect the user selected order. How do I know what the new order is?

I ended up using the change event to manually update the data source every time the user moved an item in the list. Is that the only way to know what the order should be?

[This strikes me as a bit odd; the most important part of an ordered list is knowing what the order is... yet what example makes use of a re-ordered list? Can't find one.]

Hello Gerry,

In this scenario I can suggest checking our example of the ListView with a Sortable widget:

http://dojo.telerik.com/aRUVA

Notice how on the change event of the Sortable, the oldIndex and the newIndex can be retrieved:

http://docs.telerik.com/kendo-ui/api/javascript/ui/sortable#events-change

I hope this is helpful.

Regards,
Stefan
