问题 I have a LongListSelector which is populated with some items. Each item has a submenu which can be visible or collapsed using a sliding animation. The problem is that the animation is extremely slow depending on which item you tap in the list. At the start and the end it's slow, in the middle it's smooth. I suspect that each animation frame invalidates the longlistselector which means the entire visual tree must update it's layout. I use a datatrigger to start the animation. Because of that I

Are there any alternative ways to make a fixed div that does not move that are supported on Internet Explorer 10 mobile? 回答1: div { position:fixed; width:100%;

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). But what I need is to scroll to the item at the top of the page. I could subtract manually items which are visible (by calculating

问题 I would like to compile a program written in C using Clang for 'Windows Phone' ARM target. Does anyone have experience with it? What is a better approach? 1) Building on a host running Windows 8 using Clang for Windows and MinGW. Does Clang for Windows / MinGW supports ARM by default?

Thanks in advance! 回答1: There is no
