Hi,

Is there a way to create smooth scrolling between the items with touch screen?
The animation should have acceleration and friction. Like iPhone has.

Someone already asked for this animation two years ago, so i'm wondering if this option was implemented (before I'll try to work with mouse events and calculating the speed delta myself) or is there any solution for this case?

Regards,
Yevgeniy Kiveisha

Hello Yevgeniy,

I am afraid that this is still not supported by RadCarousel and there no workarounds at the moment. We are evaluating the best possible way to support such scenarios but it is not entirely clear if and when we will be able to introduce such support.

this would be a great feature to have. I could do with something like this for my touch screen tablet apps.

RadCarousel would be really interesting with touch support for scrolling...

Hi Arnaud,

RadCarousel does not have integrated touch gesture support, however we are planning to implement it in the near future.

Haha, almost bought new wpf version)) - I thought 4 years gone - it might be implemented.

Guys, anyone tried to implement it through ScrollViewer and gesture handling?

I've tried some other solutions:
1)Infragistics - does not support touch
2)Syncfusion - demo does not event work
3)ComponentOne - touch does not work properly
Finnaly I did it by myself - with ScrollViewer and items render transform - see pic. (here in my comment you can see app screens with out of carousel http://www.telerik.com/forums/empty-items?actionMode=replyThread )
pm me if you want to know how to easily do it

Hello Eugeniy,

The touch support for our RadCarousel was introduced with Q2 2015 version. You can try it on our WPF demos.

As as side note -  we are currently working on touch improvements for all our controls along with introducing a Touch API that will allow custom touch interaction implementations.

I uploaded a video (1 - RadCarousel, 2 - Custom solution):

https://1drv.ms/v/s!Ap7l9-SeF92fjolG7VWwhV0ysaSKdA

RadCarousel behaves unpredictably from user perspective.  I'm sorry, I don't know what you mean saying "touch support", but It has nothing related to touch support. I put my finger on screen - it scrolls immediately to the item, I swipe - nothing, I release the screen - it scrolls unpredictably to another item. 50% of cases that is the last item I swiped to, but not always.

Hello ,

You can use the swipe gesture in order to scroll the items of the Carousel. However, items movement depends on the current Path which is used. In this specific example, you can control the movement of the items by modifying the path fraction. You will get a similar behavior when using the mouse.

You can check the "RadCarousel" example, where the default Path is not changed and the swipe is working as expected. You can also use the Tap gesture in order to select an item.
