I have a ComboBox in my page and I want to bind keypress event to my Kendo ComboBox when the cliend writes down any letter.

As I understand kendo doesn\'t have any k

    This one was more complicated than I thought it would be, but you can handle this by making a custom MVVM binder to attach to the keyPress event of the input element, like this:

    kendo.data.binders.widget.keyPress = kendo.data.Binder.extend({
        init: function (element, bindings, options) {
            kendo.data.Binder.fn.init.call(this, element, bindings, options);
            var binding = this.bindings.keyPress;
            $(element.input).bind("keypress", function(){binding.get();});
        },
        refresh: function () {}
    });
    

    You would bind that to a function on the view model.

    
    
    
    var viewModel = kendo.observable({
        data: [
            {text: "One", value: 1},
            {text: "Two", value: 2}
        ],
        onKeyPress: function () {
            $("#output").append("
    keyPress
    "); } });

    Here is a working jsFiddle.
