首先是带有 ObservableCollection 的视图模型和将执行 X 的命令:

First the viewmodel with the ObservableCollection and the Command that will execute the X:

private ObservableCollection<string> items = new ObservableCollection<string>() { "One", "Two", "Three" };
    public ObservableCollection<String> Items
    {
        get
        {
            return items;
        }
        set
        {
            items = value;
            NotifyPropertyChanged();
        }
    }

    public Command<String> DeleteItem
    {
        get
        {
            return new Command<string>((item) =>
            {
                if (items.Contains(item))
                {
                    items.Remove(item);
                }
                NotifyPropertyChanged("Items");
            });
        }
    }

现在是 XAML:

资源，它绑定到父"数据上下文，这是了解绑定去向的简单方法:

Resources, where it is binded to the 'parent' datacontext, this is a easy way to know where the binding is going:

<Page.Resources>
    <DataTemplate x:Key="DefaultSelectedItemsTemplate" >
        <Border x:Name="selectedItemBorder" BorderBrush="Gray" BorderThickness="1" CornerRadius="5"  Margin="5,1,1,1">
            <Grid>
                <Grid.ColumnDefinitions>
                    <ColumnDefinition Width="*"/>
                    <ColumnDefinition Width="15"/>
                </Grid.ColumnDefinitions>
                <!--<TextBlock Grid.Column="0" Text="{Binding RelativeSource={RelativeSource Self}, Path=Ime}" Margin="5,0,3,0"></TextBlock>-->
                <TextBlock Grid.Column="0" Text="{Binding}" Margin="5,0,3,0"></TextBlock>
                <Button x:Name="PART_selectedItemButton" BorderThickness="0" Grid.Column="1" Command="{Binding DataContext.DeleteItem, ElementName=ItemsControlInstance}" CommandParameter="{Binding}">X</Button>
            </Grid>
        </Border>
    </DataTemplate>
</Page.Resources>

最后是itemscontrol:

And finally the itemscontrol:

<ItemsControl x:Name="ItemsControlInstance" ItemTemplate="{StaticResource DefaultSelectedItemsTemplate}" ItemsSource="{Binding Items}"/>
