    Hello,
    I created two examples. The first works, but needs one extra template. Is it possible to build without additional templates?

    working: http://jsfiddle.net/NLN6Z/1/
    notworking: http://jsfiddle.net/g9s33/1/

    Thank

    PS
    I was unable to create links without giving me erased already written text and cant login to account in chrome.

    Hi Petr,

    Yes, but the activeData method should return observable array.
    activeData: function(){
        var result;
        $.each(this.get("data"), function(index, item){
            if (item.active == true) {
                result = item;
                return false;
            }
        });
         
        return result.rows;
    }


    Here is a link to the updated sample:

    Thank you,
    yes it makes sense. But if the object will have a more property I need to write computed property for each of his property. Is there a simpler solution?

    Hi Petr,

    Kendo MVVM bindings are not JavaScript. I am afraid that there is no straightforward approach that does not require any workarounds (such as using second template) for your scenario.
    For more information please check the source binding help topic which lists all the supported scenarios by this feature:
