Beta Coverflow : Navigation & Mouse Wheel

[Steve]

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.

Kind regards,

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.
