介绍
重新想象 Windows 8 Store Apps 之 ListView 和 GridView

ListView - 列表控件

GridView - 网格控件

示例
1、ListView 的 Demo
ListViewDemo.xaml

<Page
x:Class="XamlDemo.Controls.ListViewDemo"
xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
xmlns:local="using:XamlDemo.Controls"
xmlns:d="http://schemas.microsoft.com/expression/blend/2008"
xmlns:mc="http://schemas.openxmlformats.org/markup-compatibility/2006"
mc:Ignorable="d">

<Page.Resources>
<DataTemplate x:Key="ItemTemplate">
<StackPanel Orientation="Vertical">
<TextBlock TextWrapping="Wrap" FontSize="14.667" Text="{Binding Name}" HorizontalAlignment="Left" />
<TextBlock TextWrapping="Wrap" FontSize="14.667" Text="{Binding Age}" HorizontalAlignment="Left"/>
</StackPanel>
</DataTemplate>
<Style x:Key="ItemContainerStyle"  TargetType="ListViewItem">
<Setter Property="Width" Value="292" />
<Setter Property="Height" Value="80" />
<Setter Property="Padding" Value="0" />
<!--
即使将 Margin 设置为“0”,也无法去掉 item 之间的 margin
如果想要去掉 item 之间的 margin,请将此 Margin 属性设置为“-4”
-->
<Setter Property="Margin" Value="0" />
<Setter Property="Background" Value="Blue" />
</Style>
</Page.Resources>

<Grid Background="Transparent">
<Grid Margin="120 0 0 0">

<TextBlock Name="lblMsg" FontSize="14.667" />

<StackPanel Orientation="Horizontal" VerticalAlignment="Top" Margin="0 30 0 0">
<CheckBox Name="chkIsSwipeEnabled" Content="IsSwipeEnabled" />
<CheckBox Name="chkIsItemClickEnabled" Content="IsItemClickEnabled" Margin="10 0 0 0" />
</StackPanel>

<!--后台绑定方式为 ListView 提供数据-->
<ListView x:Name="listView" Width="300" VerticalAlignment="Top" HorizontalAlignment="Left" Margin="0 60 10 10" BorderThickness="1" BorderBrush="Red" Background="LightBlue"
ItemTemplate="{StaticResource ItemTemplate}"
ItemContainerStyle="{StaticResource ItemContainerStyle}"
ScrollViewer.VerticalScrollBarVisibility="Auto" ScrollViewer.HorizontalScrollBarVisibility="Auto"
SelectionMode="Single"
SelectionChanged="listView_SelectionChanged_1"
IsSwipeEnabled="{Binding IsChecked, ElementName=chkIsSwipeEnabled}"
IsItemClickEnabled="{Binding IsChecked, ElementName=chkIsItemClickEnabled}"
ItemClick="listView_ItemClick_1">
</ListView>

<!--
xaml 方式为 ListView 添加内容
<ListView>
<ListView.Items>
<ListViewItem>
...
</ListViewItem>
<ListViewItem>
...
</ListViewItem>
...
</ListView.Items>
</ListView>
-->
</Grid>
</Grid>
</Page>


ListViewDemo.xaml.cs

/*
* ListView - 列表控件
*     IsItemClickEnabled - item 是否可被点击
*     IsSwipeEnabled - 是否支持 swipe 操作(对于 ListView 来说,在触摸模式下,左右猛击 item 称之为 swipe)
*     SelectionMode - item 的选中模式(Windows.UI.Xaml.Controls.ListViewSelectionMode 枚举)
*         None - 不能被选中
*         Single - 只能单选
*         Multiple - 仅通过鼠标多选
*         Extended - 通过鼠标和辅助键多选(ctrl 或 shift)
*     SelectedItems - 被选中的 items 集合
*     ItemClick - item 被单击时触发的事件
*     SelectAll() - 选中全部 items
*     ScrollIntoView(object item, ScrollIntoViewAlignment alignment) - 滚动到指定的 item
*         ScrollIntoViewAlignment.Default - 与该 item 的最近边缘对齐
*         ScrollIntoViewAlignment.Leading - 与该 item 的前边缘对齐
*
*
* 注:
* IsItemClickEnabled == false && IsSwipeEnabled == false 无法响应单击事件,单击则意味着选中,无法 swipe
* IsItemClickEnabled == true && IsSwipeEnabled == false 可以响应单击事件,无法响应选中事件,无法 swipe
* IsItemClickEnabled == false && IsSwipeEnabled == true 无法响应单击事件,单击和 swipe 均意味着选中
* IsItemClickEnabled == true && IsSwipeEnabled == true 可以响应单击事件,swipe 则意味着选中
*
* 关于 SemanticZoom, item的拖动, item的尺寸可变等之后通过 GridView 来介绍
*
* 关于分页加载内容在“数据绑定”一节做介绍

using System.Collections.Generic;
using Windows.UI.Xaml.Controls;
using XamlDemo.Model;

namespace XamlDemo.Controls
{
public sealed partial class ListViewDemo : Page

}

// 单击行为的事件
private void listView_ItemClick_1(object sender, ItemClickEventArgs e)

// 选中行为的事件
private void listView_SelectionChanged_1(object sender, SelectionChangedEventArgs e)

<Setter Property="Background" Value="Blue" />
</Style>
<ItemsPanelTemplate x:Key="ItemsPanel">
<!--
注:WrapGrid 继承自 VirtualizingPanel,而 VariableSizedWrapGrid 并未继承 VirtualizingPanel
-->
<WrapGrid MaximumRowsOrColumns="3" Orientation="Vertical" VerticalChildrenAlignment="Top" HorizontalChildrenAlignment="Left" />
</ItemsPanelTemplate>
</Page.Resources>

<Grid Background="Transparent">
<StackPanel Margin="120 0 0 0">

<TextBlock Name="lblMsg" FontSize="14.667" />

<StackPanel Orientation="Horizontal" Margin="0 10 0 0">
<CheckBox Name="chkIsSwipeEnabled" Content="IsSwipeEnabled" />
<CheckBox Name="chkIsItemClickEnabled" Content="IsItemClickEnabled" Margin="10 0 0 0" />
</StackPanel>

<!--后台绑定方式为 ListView 提供数据-->
