    Hi,
    we are looking for a WPF UI - package. Telerik has many good features but a very bad performance on our tablets.
    I tried your demo application on an Acer W701 (Intel i5 u). Moving content with touch is slow as long as the touch lasts. After releasing the content scrolls nearly smoothly by "inertia". (DataGrid, Gantt, Chart, Diagram etc.)
    Our main target is out tablet platform. I can not reproduce this behavior at your compititors and at this time it would lead against Telerik.

    Hi David,

    We are aware of the problem and are currently working on major improvements and a Public Touch API that will greatly enhance the touch experience our controls offer. We are aiming to release it with our Q1 2015 release.

    Ok, thank you for your quick response.
    Is there a work around? Sadly, our customer wants to see results.
    Other options would bring us a shiny first impression but later we would miss the Gantt-Chart and some other controls :)

    Hello David,

    Most of the times the performance problem on touch devices is related to creation of automation peers. You can try disabling the creation by setting 

    AutomationManager.AutomationMode = Disabled; 

    and see if you get any improvement. Other than that, currently there isn't much you can other than disabling the TouchHandling on our side an implement custom touch logic based on the default touch events.
