longlistselector

问题 I've developed Windows Phone 8 application. In that I'm using the Long list selector to display items in the list. Everything is fine up till now.

Could you please tell me how to do this in windows phone 8. I'm looking forward for the response. 回答1: http://code.msdn.microsoft.com/wpapps/Highlight-a-selected-item

Then with WP8 it was gone and I have to use ItemRealized. It also works fine but I have side effect which that ItemRealized gives me the item which is at the bottom of current page (it could be even not visible yet).
