    Hi there

    After updating my RadGridView to the latest (for me available) Version 2013.1.403.45. The touch input behaves differently from previous versions (2012.XX)
    When I open the RadGridView on touch devices, I always need to "DoubleTab" to select an Item. I have bound the grid to the SelectedItem property.
    The first tab seems to focus the row, the second to select it. The same occurs when trying to sort on headers. The first tab does nothing, a double tab will sort.
    This is kind of frustrating, because I use the Win8Touch Theme which implies the Control should work great on touch devices.

    Is there a setting I'm missing out?

    You may suggest to update to a newer version - we are thinking about it - but we first must be sure this is going to work.

    Thank you Travis

    Hi Travis,

    Unfortunately we are not able to reproduce this behavior on our side. Would it be possible to share a small sample where we can observe the problem or provide the exact steps to reproducing it? 

    On a side note, we are currently working on a public Touch API that will allow customizations of the touch behavior. We are aiming to release it with our Q1 2015.

    OK. I could reproduce this with your Demos. I have made a video under http://www.arcavis.ch/telerik.mp4

    Hello Travis,

    Thank you for the link, however I am unable to run it on my side. Can you make sure it is the right one?

    Hi Travis,

    I was able to watch the screencast when downloading it. The problem you are experiencing looks like a problem we had a while back. Are you using our latest binaries? Have you tried it with them? Do you get the same results?

    Hi Nick

    Thanks for your answer. I'm happy It is a known issue but I'm afraid version 2013.1.403 is the latest I could get. The previous versions worked, do you have a fix for me, or can I "downgrade" to a previous version?

    Thanks

    Hello Travis,

    The problem is that on more sensitive(capacitive) displays the TouchMove event is fired a lot more often. This leads to a misinterpretation of the gesture and using it as a swipe instead. Since we still don't offer a publi API to control the touch events there is no workaround for the issue. 
    You can try getting an older version from your telerik profile.
