    I am trying to append a scroll view that will load once I know the height ( I want it to be adapted to the phone screen )

    So in my Html, I am doing :

    <div data-role="view" data-title="Login" id="loginView" data-init="showLoginSlider">
        <header data-role="header">
            <div class="iOS7" style="height:20px"></div>
        <div data-role="content" class="login" id="loginContent">
            <div id="loginScroller"></div>
            <div style="height: 160px; overflow: hidden;">
                <div id="fbconnect"> <!-- Sign up with FB instead of Login -->
                    <a href="#" id="loginbutton" ><img src="content/buttons/facebook-login.png" alt="facebook login button"></a>
                <div id="privacyPolicy">
                        We will never interact on Facebook without your permission
                        Your personal data is removed upon deleting your profile
                        We will never post on your wall
                    <span id="boring">Read our <a href="views/termsandconditions.html">Terms & Conditions</a> and our <a href="views/privacypolicy.html">Privacy Policy</a>.</span>
        <div id="fb-root"></div>
    <!-- Template for the events -->
    <script id="loginScroller-template" type="text/x-kendo-template"><div class="login-scrollV" id="page1" data-role="page">
        </div><div class="login-scrollV" id="page2" data-role="page">
        </div><div class="login-scrollV" id="page3" data-role="page">

    And in my Javascript (this is done after Cordova and Kendo UI initialization) :

    function showLoginSlider ()
        //Remove previous content
        var scrollView = $( "#loginScroller" ).data( "kendoMobileScrollView" );
        if ( typeof scrollView !== typeof undefined )
            $( "#loginScroller" ).empty();
        var maxHeight = $( "#loginContent" ).height();
        alert( maxHeight );
        var loginScrollerHeight = maxHeight - 200;
        var slidesHeight = loginScrollerHeight - 25;
        $( "#loginScroller" ).height( loginScrollerHeight );
        $( ".login-scrollV" ).height( slidesHeight );
        var template = kendo.template( $( '#loginScroller-template' ).html(), {useWithBlock:false} );
        $( "#loginScroller" ).kendoMobileScrollView({
            template : template,
            enablePager: true,
            contentHeight: loginScrollerHeight

    But nothing is appended. Why ?
    isn;t it a better way to do it ? But I still need to get my height with Javascript.

    Many thanks.

    Hi Yohann,

    The reason you are not seeing any items/pages in your ScrollView is that it has no data source. You have to assign it a data source that holds the items that the control needs to render on each page. Here is a simple example with your code:
        dataSource: ["facebook", "google+", "twitter"],
        template: template,
        enablePager: true,
        contentHeight: loginScrollerHeight

    I think you also misunderstood how to use the template. I think you tried to add the data you need to show in the template, which is wrong. There are two types of ScrollView templates as you can see here. Using a template for a single item, your template would look like this:
    <script id="loginScroller-template" type="text/x-kendo-template">
        <div class=".login-scrollV">#= data #</div>

    Of course, in a real scenario you will need a dataSource with JS objects instead of strings. Again, you can refer to the ScrollView templates article to see how you can access the objects and properties.

    I hope this information was helpful. Let me know if you still have questions.
