    I'd like to customize the Carousel. I'm using the Coverflow example, version 2009.3.1103.35, .NET 3.5 SP1, Vista x64 and VS 2008.

    What I'm trying to achieve here is a smoother animation than the default per-element animation. So currently to move you can either click on an image/control within the carouselpanel or scroll using the scrollviewer. I want to make this smoother (think iPhone scrolling) by preventing image clicking and relaying the mouse move delta to the scrollviewer.

    So I'm handling the coverflow control's mouse left click event (and set Handled to True) to set a reference point and prevent clicks reaching the images. Then I'm handling the mouse move event and retrieving the delta by subtracting destination and source X from the two MouseEventArgs provided by the event.

    How can I relay this delta (of type double) to the scrollviewer (incrementally) to simulate this effect? I'm guessing the control's ScrollOwner property may play a role, but I would like your input on this. Could I perhaps use the RaiseEvent method?

    Hi Julian,

    It would be a really nice feature to have the option to move the carousel by non-discrete amount but for the time being I am afraid that this is impossible. Currently the default movement behavior cannot be disabled and an carousel will always move when you click on an item. 

    To be able to support such scenarios we should modify the internal carousel logic but I am not sure if we will be able to start working on this soon. I will try something out in the next few days to see if we can introduce this without a lot of modifications and report back.

    Best wishes,

    Is this still the case, even in Q1 2011?

    Hi Shrinivas,

    Basically, this behavior is still the same as modifying it will require changing the internal logic of the carousel, which at this time will not be a recommended thing to do. 
    Please, excuse us in case we cause any inconvenience.
