[英]How to select a single TextBlock in a DataTemplate
我的WPF應用程序中有此DataTemplate
。
當我單擊一個按鈕時,我需要獲取TextBlock Name="titleCategory"
並更改其顏色。
目前,我無法選擇TextBlock
。
您能給我一個簡單的解決方案嗎?
<DataTemplate x:Key="CategoriesSelectedDataTemplate">
<Grid>
<Grid.RowDefinitions>
<RowDefinition Height="Auto"/>
<RowDefinition Height="*"/>
</Grid.RowDefinitions>
<Border d:LayoutOverrides="Width, Height"
CornerRadius="5"
HorizontalAlignment="Stretch"
Background="Transparent" >
<TextBlock Name="titleCategory" TextWrapping="Wrap"
Text="{Binding CapitalizedDescription, FallbackValue=Category}"
Foreground="Red"
/>
</Border>
<!-- 1L main menu HOVER -->
<Custom:SurfaceListBox
d:LayoutOverrides="Width"
ItemsSource="{Binding Shops}"
ItemTemplate="{DynamicResource ShopUnselectedSurfaceListDataTemplate}"
Grid.RowSpan="1"
Grid.Row="1"
SelectionChanged="shopListBox_SelectionChanged"
ItemContainerStyle="{DynamicResource CategoriesSurfaceListBoxItemStyle}"
SelectionMode="Multiple"/>
</Grid>
</DataTemplate>
我用這段代碼解決了
var elem = (FrameworkElement)sender;
TextBlock myTextBlock = (TextBlock)elem.FindName("titleCategory");
myTextBlock.Foreground = System.Windows.Media.Brushes.Yellow;
