AfterItemSelect event occurs after a WebCoverFlow Item is selected.
And ActiveItemClick event occurs when WebCoverFlow ActiveItem is clicked. The active item is the item that located in the center, the rest of the items called WebCoverFlow item.

I enclosed a video that shows when those events are triggered.

Hope this helps.

Hi Yudi,

Thanks for your great help, actually, I am trying same with the video, but still can't work; and an error popup up when I try to open the xaml in Blend, please see attached.

Does this CoverFlow derive from ItemControl?

BTW,  I can't set the start up index. please see  here http://www.intersoftpt.com/Community/WebAqua/How-to-programmatically-set-CustomStartIndex-of-CoverFlow/

Thanks,

Yuanzi

As shown in the attached video on my previous post, I didn’t find any issue when running my test page. I also unable to repro the error popup when try to open the xaml in Blend.

Do you have any running simple sample that replicates the issue? If you do, could you please send us the sample for further investigation?
