我是 wpf 的新手,我希望这是一个简单的问题。
我创建了一个简单的模板来显示一些分组项目
目前,当我单击 ItemsClick 被调用的项目之一时(如预期的那样)
private void itemGridView_ItemClick(object sender, ItemClickEventArgs e)
{
MyCustomClass selectedItem = (MyCustomClass)e.ClickedItem;
GridView g = (GridView)sender;
我可以通过投射 e.ClickedItem 和来自发件人的网格来获取类对象的副本。但是我没有看到如何获得对我在模板中添加的自定义项目的引用,例如,如果我想更改 testName TextBlock 中的文本?
模板:
<DataTemplate x:Key="MyTestTemplate">
<Grid HorizontalAlignment="Left" >
<Grid.RowDefinitions>
<RowDefinition Height="Auto"/>
</Grid.RowDefinitions>
<Border Background="{StaticResource ListViewItemPlaceholderBackgroundThemeBrush}" Grid.RowSpan="3">
<Image Source="{Binding ThumbnailUrl}" Stretch="Fill" Width="175" Height="175" />
</Border>
<Image Source="{Binding MyCustomImage}" Height="30" Width="30" Grid.RowSpan="3" Margin="0,0,0,30"/>
<Grid x:Name="ItemDetails" VerticalAlignment="Bottom" Height="75" Margin="0,0,0,2" Background="{StaticResource ListViewItemOverlayBackgroundThemeBrush}">
<Grid.RowDefinitions>
<RowDefinition Height="40"/>
<RowDefinition Height="Auto"/>
</Grid.RowDefinitions>
<TextBlock x:Name="testName" Text="{Binding Name}" Grid.Row="0" Foreground="{StaticResource ListViewItemOverlayForegroundThemeBrush}" MaxWidth="100" MaxHeight="80" TextWrapping="Wrap" HorizontalAlignment="Left" Style="{StaticResource TitleTextStyle}" Margin="5,0,5,0"/>
<TextBlock Text="{Binding Address}" Grid.Row="0" HorizontalAlignment="Right" Foreground="{StaticResource ListViewItemOverlaySecondaryForegroundThemeBrush}" Style="{StaticResource
