This example demonstrates passing a single option to bind against the value of the DateTimePicker widget.

<input data-bind="kendoDateTimePicker: startDate" />
<hr/>
<div data-bind="text: startDate"> </div>

var ViewModel = function() {
    this.startDate = ko.observable(new Date());
};

                            ko.applyBindings(new ViewModel());

This example demonstrates passing additional options in the data-bind attribute with value now being explicitly specified. The setToNow button makes an update to the view model to show that the widget responds accordingly.

<input data-bind="kendoDateTimePicker: { value: startDate, max: maxDate, min: minDate }" />
<hr/>
<button data-bind="click: setToNow">Set to Now</button>
<hr/>
<div data-bind="text: startDate"> </div>

var ViewModel = function() {
    this.startDate = ko.observable(new Date(2012, 10, 30, 5, 30));
    this.maxDate = new Date(2012, 11 , 31, 2, 30);
    this.minDate = new Date(2012, 0, 1, 9, 30);
    this.setToNow = function() {
        this.startDate(new Date());
    };
};

                            ko.applyBindings(new ViewModel());

This example demonstrates setting global options in ko.bindingHandlers.kendoDateTimePicker.options. This helps to simplify the markup for settings that can be used as a default for all instances of this widget.

<input data-bind="kendoDateTimePicker: startDate" />
<hr/>
<button data-bind="click: setToNow">Set to Now</button>
<hr/>
<div data-bind="text: startDate"> </div>

var ViewModel = function() {
    this.startDate = ko.observable(new Date(2012,10,30, 5, 30));
    this.setToNow = function() {
        this.startDate(new Date());
    };
};

ko.bindingHandlers.kendoDateTimePicker.options = {
    min: new Date(2012, 0, 1, 9, 30),
    max: new Date(2012, 11, 31, 2, 30)
};

                            ko.applyBindings(new ViewModel());
