    Hi,

    I am developing a WPF application for a Windows 7 tablet, and I am wondering if there is a way to allow a RadTileView to be scrolled by using touch / finger gestures?

    Thanks!

    Hi Stephen,
    We have plans to add touch support for all our controls, but unfortunately I can't give you any specific date. The first controls supporting it might be available for Q3 but, again, i can't guarantee this.
    For now you could try to implement your own touch logic using the Touch/Manipulation events and if you have further questions please feel free to ask.

    Kind regards,

    Hello Alex,

    We have implemented touch support for RadTreeView in Silverlight and WPF platforms. You could check our latest 2013 Q1 release.

    Furthermore, we did not implemented touch support for RadTileView because our initial research showed almost no one is interested in it. However, if we detect increasing demand we shall implementing touch for RadTileView too.

    Kind regards,

    Hi,

    I'm working with WPF. How can I move items into telerik:RadTileView with touch (by finger gesture)? I would really appreciate if you got any solution regarding the issue as soon as possible. I'm stuck with that one.

    Also, I'm stuck with telerik:RadGridView row cell click with touch (by finger gesture)(Private Sub GV_MouseLeftButtonDown(sender As Object, e As RoutedEventArgs))  to open a detail window to edit. I can open the window but problem is if I want to hit any button it first focus and then I need to click the button again to do that. But when I open the detail window by clicking any button it's fine. Please provide me some solution with gridview as well.

    Please note, everything fine with mouse but problem with touch.

    Thanks,

    Regards,

    Hassan

    Hi Hassan,

    Could you please elaborate a little bit more on "How can I move items into telerik:RadTileView with touch"? Do you mean drag and drop items in the tileView or just reorder existing items because the reordering comes out of the box and it's just like with a mouse - press and hold a header of an item and then move it around.

    Usually clicking on a button in the GridView is handled by Mouse only. In order to be able to fire the Click with touch, you have to set TouchManager.IsTouchHitTestVisible to false on the Button. 

    Hope this helps!

    Hi Nik,

    Thanks for your reply message. Anyway, I explain the issues below:

    RadTileView: I'm trying to reorder items by finger, it's not working but with mouse everything fine.

    RadGridView: When click on any row and open a modal window according to row ID, I'm facing a problem. And it's after opening the modal window it does not do anything at the very first click on any button or controls but after that it's ok. I close the modal window and open modal window againg by clicking any row it's the same problem first time. But with the mouse everything ok. Don't know why it's happening?

    Is there any telerik control for capturing webcam picture from a button click?


    Thanks and regards,

    Hassan

    Hi Hassan,

    We're not aware of such issue in the RadTileView so could you please tell us if you're using custom styles/itemTemplates or you've placed the tileView in a control that could handle the touch (IsManipulationEnabled=True) ? We'll appreciate it if you could send us a sample project demonstrating the problem.

    As to the GridView problem you are facing, we fixed an issue like that a while ago, could you try it out with our latest sources? Unfortunately, there isn't a workaround that you can implement. 

    Regarding the Webcam button, no we don't offer such a control since it is very specific for very custom scenarios. You can search for the Windows api on how to manipulate a peripheral devices like a webcam and execute the desired logic on button click.

    Hope this makes sense! 

    Regards,
