如何从UWP背后的代码中添加listView和方向为水平？

Question

我必须从ADER背后的代码中实现此语法，该如何

    <ListView>
        <ListView.ItemsPanel>
            <ItemsPanelTemplate>
                <ItemsStackPanel Orientation="Horizontal" 
                     />
            </ItemsPanelTemplate>
        </ListView.ItemsPanel>
    </ListView>

从UWP背后的代码中实现属性元素语法？

Answer 1

您可以这样实现。

<ListView x:Name="AwesomeListView" ItemsSource="{x:Bind Items}">
    <!--
    <ListView.ItemsPanel>
        <ItemsPanelTemplate>
            <ItemsStackPanel Orientation="Horizontal" />
        </ItemsPanelTemplate>
    </ListView.ItemsPanel>
    -->
</ListView>

public sealed partial class MainPage : Page
{
    public List<int> Items { get; set; } = new List<int>() { 1, 2, 3, 4, 5 };

    public MainPage()
    {
        this.InitializeComponent();

        this.AwesomeListView.ItemsPanel = CreateItemsPanelTemplate(Orientation.Horizontal);
    }

    ItemsPanelTemplate CreateItemsPanelTemplate(Orientation orientation)
    {
        string xamlString =
            $@"<ItemsPanelTemplate
                    xmlns='http://schemas.microsoft.com/winfx/2006/xaml/presentation'
                    xmlns:x='http://schemas.microsoft.com/winfx/2006/xaml'>
                    <ItemsStackPanel Orientation='{orientation}' />
                </ItemsPanelTemplate>";

        return (ItemsPanelTemplate)XamlReader.Load(xamlString);
    }
}

如何从UWP背后的代码中添加ListView？

的水平。

对于在后面的代码中制作itemSpaneltemplate，您可以分析itemspaneltemplate字符串，然后将其传递到ListView的iteg> itemspanel。

private void ApplyItemsStackPanelAsItemsPanel(ItemsControl itemsControl)
{

    var itemsPanelTemplateXaml =
        $@"<ItemsPanelTemplate xmlns='http://schemas.microsoft.com/winfx/2006/xaml/presentation'
                          xmlns:x='http://schemas.microsoft.com/winfx/2006/xaml'>
           <ItemsStackPanel Orientation='Horizontal'/>
       </ItemsPanelTemplate>";

    itemsControl.ItemsPanel = (ItemsPanelTemplate)XamlReader.Load(itemsPanelTemplateXaml);

}

用法

private void BuildListView()
{
    var listview = new ListView();
    ApplyItemsStackPanelAsItemsPanel(listview);
    listview.ItemsSource = new string[] { "1", "2", "3", "4" };
    this.Content = listview;
}
