Issue:

SmartForms can be inserted in SharePoint pages using K2 Form Viewer or K2 SmartForms Viewer, which inherits from the SharePoint Page Viewer web part.  When the form is viewed on a mobile device, such as an iPad, the scroll bar is not available which makes the form unusable. To resolve this issue, you must enable page scrolling by adding a script to the SharePoint page hosting the K2 Form Viewer. Follow the steps detailed in the workaround below:

Workaround:

  1. As a SharePoint administrator edit the SharePoint page that contains the K2 Forms Viewer web part.
  2. In the ribbon choose Insert -> Embed Code.
  3. Paste the following code:
    Note: 
    1. The sample script below shows the configuration for an iPad. Customize the script if you are using a different mobile device.
    2. The widths and heights in the script can be adjusted to ensure the form displays correctly on the targeted devices.

    <script type="text/javascript">
    var is_iPad = navigator.userAgent.match(/iPad/i) != null;
    function _fixIframeScrolling()
    {
        var iframe = document.getElementsByTagName("iframe")[0];
        iframe.setAttribute("scrolling", "yes");
        iframe.height = "100%";
        iframe.width = "100%";
        iframe.style.cssText = "display:block;";
        iframe.parentElement.style.cssText = "height: 450px; width: 750px; max-width: 750px; max-height: 450px; overflow: auto; -webkit-overflow-scrolling: touch;";
        iframe.parentElement.parentElement.style.cssText = "height: 460px; width: 760px;";
    }
    if(is_iPad)
    {
    _spBodyOnLoadFunctionNames.push("_fixIframeScrolling")
    }
    </script>
  4. Click Insert.
  5. Save the page.
