在每个ListBox项中添加Name属性

Question

我有一个WPF项目，其中我有Resource Dictionary我存储我的样式。在这本词典中，我有ListBoxItem Template，看起来像这样。

    <DataTemplate x:Key="GenreStyle">
    <Grid Width="150" Height="150" Background="Transparent">
        <Image x:Name="GenreImage" Tag="{Binding Genre}" RenderOptions.BitmapScalingMode="HighQuality" Source="{Binding GenreSource}" Width="140" Height="140" MouseEnter="GenreImage_MouseEnter" MouseLeave="GenreImage_MouseLeave" MouseLeftButtonDown="GenreImage_MouseLeftButtonDown" MouseLeftButtonUp="GenreImage_MouseLeftButtonUp"/>
    </Grid>
</DataTemplate>

现在我要做的是，当我点击每个项目时，请阅读图像Tag。 我现在正在做的是：

private void StationsListLB_PreviewMouseLeftButtonUp(object sender, System.Windows.Input.MouseButtonEventArgs e)
{
    var item = ItemsControl.ContainerFromElement(StationsListLB, e.OriginalSource as DependencyObject) as ListBoxItem;
    if (item != null)
    {
       MessageBox.Show(??????);
    }
}

Answer 1

好的想通了。我只需抓住System.Windows.Input.MouseButtonEventArgs。 然后非常简单：

private void StationsListLB_PreviewMouseLeftButtonUp(object sender, System.Windows.Input.MouseButtonEventArgs e)
{
    var item = ItemsControl.ContainerFromElement(StationsListLB, e.OriginalSource as DependencyObject) as ListBoxItem;
    if (item != null)
    {
        var opa = e.OriginalSource as System.Windows.Controls.Image;
        MessageBox.Show(opa.Tag.ToString());
    }
}
