有没有什么方法可以获得粘贴到ItemsControl的数据的索引,单击按钮时?获取来自ItemsControl的数据绑定索引
<ItemsControl x:Name="ic_schranke" DataContext="{Binding Schranke}" >
<ItemsControl.ItemTemplate>
<DataTemplate >
<Button Height="80" x:Name="btn_open" Click="btn_open_Click" HorizontalAlignment="Stretch" Style="{StaticResource TransparentStyle}">
<Grid HorizontalAlignment="Stretch">
<Grid.ColumnDefinitions>
<ColumnDefinition Width="1*"/>
<ColumnDefinition Width="2*"/>
<ColumnDefinition Width="1*"/>
</Grid.ColumnDefinitions>
<Grid.RowDefinitions>
<RowDefinition Height="1*"/>
<RowDefinition Height="30*"/>
<RowDefinition Height="1*"/>
</Grid.RowDefinitions>
<Rectangle x:Name="rect" Grid.ColumnSpan="3" Grid.Row="1" Opacity="0.65" Grid.Column="0" Fill="#FFCEEAFF"/>
<Border CornerRadius="25" Height="50" Width="50" HorizontalAlignment="Center" Grid.Column="0" Grid.Row="1">
<Border.Background>
<ImageBrush ImageSource="/Assets/schranken.jpg" />
</Border.Background>
</Border>
<TextBlock Name="schranken_name" Grid.Column="1" Grid.Row="1" Text="{Binding name}" VerticalAlignment="Center" HorizontalAlignment="Center" FontWeight="ExtraLight" Foreground="Black" />
</Grid>
</Button>
</DataTemplate>
</ItemsControl.ItemTemplate>
</ItemsControl>
这里是一个被绑定到IC样本数据:
List<Schranke> elements;
public UserPage()
{
this.InitializeComponent();
elements = new List<Schranke>();
for (var i = 1; i < 15; i++)
elements.Add(new Schranke() { name = $"Schranke NR:{i}" });
this.ic_schranke.ItemsSource = elements;
}
这里是在按钮单击事件代码:
private async void btn_open_Click(object sender, RoutedEventArgs e)
{
Grid grid = (sender as Button).Content as Grid;
//Debug.WriteLine($"content {tb.Text} clicked");
var tmp_background = grid.Background;
grid.Background = new SolidColorBrush(new Windows.UI.Color() { A = 255, R = 78, G = 170, B = 44 });
VibrationDevice testVibrationDevice = VibrationDevice.GetDefault();
testVibrationDevice.Vibrate(System.TimeSpan.FromMilliseconds(150));
await Task.Delay(3000);
grid.Background = tmp_background;
}
为什么不使用命令而不是事件(更好的做法),并发送命令参数列表中的对象?或者至少是ID。 我不能给出一个示例代码,没有Schranke的定义 – MichaelThePotato
Schranke是一个字符串名称只作为成员的类。 – student96
