    Hi

    Im using the 2009.3.916.1030 build coverflow and I cannot see how to display the scrollbar navigation which was achievable in the previous release using the NavigationPanelVisibility property - this property seems to have disappeared ?

    Also I want to be able to scroll the mouse wheel to navigate through my coverflow items and have tried implementing the MouseWheelEvent using a variation of the code in this page however my event handler never gets called.

    Any ideas ?

    Sample code is below.  Thanks

    XAML
    <telerikNavigation:RadCoverFlow x:Name="coverFlow" Background="Transparent"
                OffsetY="75"
                CameraViewpoint="Center"
                RotationY="40"
                ItemScale="0.75"
                ItemWidth="225"
                ItemHeight="225"
                 MouseWheel="coverFlow_MouseWheel"
                ContentType="Image">

    .CS
     void coverFlow_MouseWheel(object sender, MouseWheelEventArgs e) 
            { 
                if (e.Delta < 0
                { 
                    if (this.coverFlow.SelectedIndex < this.coverFlow.Items.Count
                        this.coverFlow.SelectedIndex += 1; 
                } 
                else 
                { 
                    if (this.coverFlow.SelectedIndex > 0) 
                        this.coverFlow.SelectedIndex -1
                }  
            }

    Hello Steve,

    The NavigationPanel was removed from the CoverFlow, because in Silverlight 3 you could use Bindings with ElementName and easily implement it outside of the CoverFlow control. Please, take a look at the following article that gives more information how you can achieve this: http://blogs.telerik.com/hristoborisov/posts/09-10-06/navigation_for_coverflow.aspx.

    The MouseScroll should work out-of-the-box without implementing it from the outside. Could you please open a support ticket and send us a project that represents the problem? This would help us a lot in finding out what the problem is.

    For some reason Mouse Wheel is not working for me. I have seen it on a demo app but within my code it is not working.

    Hi Martin,

    Could you please, open a new support ticket and send us a simple application that can be used to observe the problem? In RadCoverFlow we are using the Silverlight mouse wheel events, so generally this could be a problem in Silverlight, or there is another control that is handling the events and they do not reach the CoverFlow.
