This example demonstrates generating a basic QR Code.

<div data-bind="kendoQRCode: {
    value: selectedLink,
    errorCorrection: 'M',
    size: 160
}"></div>
<hr/>
<input data-bind="kendoDropDownList: { data: links, value: selectedLink, dataTextField: 'name', dataValueField: 'url' }" />

var ViewModel = function() {
    this.selectedLink = ko.observable("http://knockoutjs.com");
    this.links = ko.observableArray([
        { url: "http://knockoutjs.com", name: "Knockout" },
        { url: "http://kendo-labs.github.io/knockout-kendo/index.html", name: "KO-Kendo" },
        { url: "http://demos.telerik.com/kendo-ui/", name: "Kendo UI" }
    ]);
};

                            ko.applyBindings(new ViewModel());
