问题 I am developing a WinRT app. One of the requirements is that the app should have a "timed logout" feature.

问题 Yo, So I've been developing a Universal Windows Store app in Visual Studio 2013 on one machine, and wanted to continue developing it on an another machine running Windows 10 Technical Preview.

Below is what i have come up with, it does not work. I have two grids within the templates and was hoping to simply show and hide the grids depending on if the listview item is selected.
