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

问题 I am trying to get a listview to display a list of items made up of textblocks... when the listview item is clicked i would like to show instead a list made up of textboxes... 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.
