    When DataViz charts are displayed on an iOS device, tooltips are shown on first touch of a series. The series click event is then fired on second touch.

    From what I can work out, it appears that this is achieved by handling the touchEnd event and invoking event.preventDefault() to stop the click event happening, which then allows the tooltip to be shown to the user. Unfortunately, there seems to be a bug in the implementation, as once a tooltip has been displayed, any clicks to any elements on the page (even outside the chartarea) are prevented.

    Has anybody found any simple workaround for this issue? I tried handling touchStart and then firing a click event against the target element (i.e. so the browser thinks it's a click event rather than a touch event, thereby bypassing touchEnd), but this causes bugs elsewhere (e.g. 'pseudo' double clicks on dropdowns causing them to open then immediately close). Beyond that, I'm running out of ideas...!

    Does anybody from Telerik have any thoughts on this matter?

    Hi,

    This is a known issue with the official release. Please, update to the latest internal build or the first service pack, when it becomes available.

    A side effect from the fix is that tooltips are no longer displayed. We'll investigate.

    Apologies for the caused inconvenience.

    I just updated to the newest version of the Kendo UI (12/12/2012) and I'm still experiencing the same issue from iPads and iPhones.  When will this issue be resolved?

    Hello,

    I'm no longer able to reproduce the original problem with the internal build. I'm testing with iPad and iPhone with iOS 6.0.1

    Can you please double check that you're using the updated version?

    All the best,

    Hi George,

    The internal builds are available only for paid customers. The next official release of the product (which non-paid users can download) will include the fix.

    Kind regards,
