我想这就是您要找的。每个项目都是一个按钮，其中包含一个图像和一个标签。单击该按钮将调用带有参数的命令(在窗口的 DataContext 上)。

<ItemsControl.ItemTemplate>
    <DataTemplate DataType="viewModels:Card">
        <Button Command="{Binding DataContext.QueryCommand, RelativeSource={RelativeSource FindAncestor, AncestorType=Window}}" 
                CommandParameter="{Binding Path=id}">
            <StackPanel>
                <Image Width="100" Source="{Binding Path=cover}"/>
                <Label Content="{Binding Path=title}" HorizontalContentAlignment="Center"/>
            <StackPanel>
        </Button>
    </DataTemplate>
</ItemsControl.ItemTemplate>
