Как установить другой цвет фона при нажатии элемента ListView для приложения metro/WinRT?
Я пытался примерно полчаса самостоятельно, используя Expression Blend 5 Beta и Visual Studio 11 Beta, но не могу понять, что должно быть довольно тривиальной задачей о том, как применить другой цвет фона, когда вы нажимаете на ListView отметьте стандартное темно-зеленое с галочкой, которая, как представляется, поставляется стандартным для приложений WinRT с Windows 8 Consumer Preview.
Я считаю, что мне нужно <VisualStateManager/> декларация внутри моего XAML внутри <DataTemplate/> моего ListView (так же, как я сделал на Button контроль), но не может найти способ заставить вкладку "Состояния" функционировать в Blend для начала записи этих действий, и, кроме того, я не уверен, какое имя назвать VisualState после того, как я в конце концов разберусь, как это сделать.
Например, настройка Pressed визуальное состояние для Button было довольно легко после того, как я щелкнул правой кнопкой мыши и отредактировал его шаблон элемента управления, я смог получить доступ к вкладке "Состояния" в Blend и начать записывать свои действия Pressed, Disabled, PointerOver и т. д., но это не так просто с ListView или, возможно, с другими элементами управления?
Из-за того, что Blend 5 и VS 11 являются бета-версиями, трудно понять, что может быть некодированной функцией в пользовательском интерфейсе Blend, или просто я делаю что-то неправильно! Поэтому я ценю любую помощь, которую может оказать любой. Спасибо

Состояние выбора должно быть частью ItemContainerStyle - либо в форме визуального состояния, либо в виде триггера, но ItemContainerStyle, по-видимому, не отображается в представлении конструктора, поэтому его трудно изменить, но вы можете просто добавить ListViewItem в Ваш XAML и дизайнер с радостью расскажут вам, каков его стиль и шаблон, чтобы вы могли изменить его.
Вы можете изменить стиль в вашем GridView или ListView, установив
ItemContainerStyle="{StaticResource ListViewItemStyle1}"
И добавление этих ресурсов в словарь активных ресурсов (например, Page.Resources):
<SolidColorBrush x:Key="ListViewItemHighlightBrush2" Color="Pink" />
<SolidColorBrush x:Key="ListViewItemCheckHintGlyphBrush2" Color="Red" />
<SolidColorBrush x:Key="ListViewItemPointerOverBrush2" Color="Purple" />
