如何在GridView中的ListViewItemPresenter中更改SelectedBackground
我有一个Clickable-Gridview insde HubSection：
现在，每次我点击该集线器时，GridView（SelectedBackground）周围都会出现蓝色边框。
在LiveVisualTree中，它向我显示，边框来自GridViewItem内的“ListViewItemPresenter”控件。 因此，我从原始控件修改了样式并将其粘贴到Page.Resources标记中。
<ListViewItemPresenter ContentTransitions="{TemplateBinding ContentTransitions}" SelectionCheckMarkVisualEnabled="True" CheckBrush="{ThemeResource SystemControlForegroundBaseMediumHighBrush}" CheckBoxBrush="{ThemeResource SystemControlForegroundBaseMediumHighBrush}" DragBackground="{ThemeResource ListViewItemDragBackgroundThemeBrush}" DragForeground="{ThemeResource ListViewItemDragForegroundThemeBrush}" FocusBorderBrush="{ThemeResource SystemControlForegroundAltHighBrush}" FocusSecondaryBorderBrush="{ThemeResource SystemControlForegroundBaseHighBrush}" PlaceholderBackground="{ThemeResource ListViewItemPlaceholderBackgroundThemeBrush}" PointerOverBackground="{ThemeResource SystemControlHighlightListLowBrush}" PointerOverForeground="{ThemeResource SystemControlHighlightAltBaseHighBrush}" SelectedBackground="White" SelectedForeground="{ThemeResource SystemControlHighlightAltBaseHighBrush}" SelectedPointerOverBackground="{ThemeResource SystemControlHighlightListAccentMediumBrush}" PressedBackground="{ThemeResource SystemControlHighlightListMediumBrush}" SelectedPressedBackground="{ThemeResource SystemControlHighlightListAccentHighBrush}" DisabledOpacity="{ThemeResource ListViewItemDisabledThemeOpacity}" DragOpacity="{ThemeResource ListViewItemDragThemeOpacity}" ReorderHintOffset="{ThemeResource ListViewItemReorderHintThemeOffset}" HorizontalContentAlignment="{TemplateBinding HorizontalContentAlignment}" VerticalContentAlignment="{TemplateBinding VerticalContentAlignment}" ContentMargin="{TemplateBinding Padding}" CheckMode="Inline"/>
但这不适合我。 SelectedBackground-Border仍为蓝色。 但为什么？ 我的错误在哪里？
您应该覆盖GridViewItem样式并将新样式设置为GridView 。 在页面资源中声明您的新样式：
并设置：
ps您还可以覆盖Exanded样式
