[英]UWP - replace StackPanel to make inner content stretchable inside GridView
[英]UWP - Customizing ListBoxItemStyle with Stackpanel Content
我正在为UWP-XAML中的ListBoxItem的样式概念苦苦挣扎。
我要实现的是一种列表框样式,其中的项目由两个TextBlocks的StackPanel组成,例如,当按下PressedSelected时,这会改变两个TextBlocks的前景。
在下面的ListBox示例中,我只能在标准ListBoxItemStyle中设置ContentPresenter的样式,并且两个TextBlocks一起更改。
<ListBox>
<ListBox.ItemTemplate>
<DataTemplate x:DataType="local:DataSet">
<StackPanel>
<TextBlock x:Name="number" Text="{x:Bind Number}"/>
<TextBlock x:Name="name" Text="{x:Bind Name}"/>
</StackPanel>
</DataTemplate>
</ListBox.ItemTemplate>
</ListBox>
您必须编辑ItemContainer的样式。 用stackpanel及其内容替换ContentPresenter。 但是我使用Binding而不是x:Bind。 似乎无法在样式内使用x:Bind
<Style TargetType="ListBoxItem" x:Key="ListViewStyle">
<Setter Property="FontFamily" Value="{ThemeResource ContentControlThemeFontFamily}" />
<Setter Property="FontSize" Value="{ThemeResource ControlContentThemeFontSize}" />
<Setter Property="Background" Value="Transparent"/>
