- ListView
- GridView
示例
1、ListView 的示例
Controls/CollectionControl/ListViewBaseDemo/ListViewDemo.xaml
<Page x:Class="Windows10.Controls.CollectionControl.ListViewDemo" xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation" xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml" xmlns:local="using:Windows10.Controls.CollectionControl" xmlns:d="http://schemas.microsoft.com/expression/blend/2008" xmlns:mc="http://schemas.openxmlformats.org/markup-compatibility/2006" mc:Ignorable="d" xmlns:common="using:Windows10.Common"> <Page.Resources> <Style x:Key="ListViewItemStyle" TargetType="ListViewItem"> <Setter Property="Background" Value="Transparent"/> <Setter Property="Template"> <Setter.Value> <ControlTemplate TargetType="ListViewItem"> <!-- ListViewItemPresenter - ListViewItem 的 Presenter(繼承自 ContentPresenter, 請參見 /Controls/BaseControl/ContentControlDemo/ContentPresenterDemo.xaml) 有好多屬性,詳見文檔 預設樣式就是 generic.xaml 中的 <Style TargetType="ListViewItem"> 節點 如果需要自定義的話,那麼就在 generic.xaml 中的 <Style TargetType="ListViewItem" x:Key="ListViewItemExpanded"> 節點的基礎上修改 如果還不能滿足要求的話就通過繼承 ContentPresenter 來實現自定義的 ContentPresenter --> <!-- 此處的 TemplatedParent 是 ListViewItem 這裡借用 Tag 保存一下 ListViewItem 的 IsSelected,之後的數據模板可以綁定 ListViewItemPresenter 的 Tag,從而實現數據模板間接綁定 ListViewItem 的 IsSelected 此處通過 Tag 屬性做中轉,如果 Tag 有別的用處的話,那麼就自己寫個附加屬性做中轉吧 --> <ListViewItemPresenter Margin="10" SelectedBackground="Red" SelectedPointerOverBackground="Red" Tag="{Binding IsSelected, RelativeSource={RelativeSource Mode=TemplatedParent}, Mode=TwoWay}" /> </ControlTemplate> </Setter.Value> </Setter> </Style> <common:BooleanToVisibilityConverter x:Key="BooleanToVisibilityConverter" /> </Page.Resources> <Grid Background="Transparent"> <!-- ListView - ListView 控制項(繼承自 ListViewBase, 請參見 /Controls/CollectionControl/ListViewBaseDemo/) ListView 的預設佈局控制項是 ItemsStackPanel,請參見 /Controls/CollectionControl/ItemsControlDemo/LayoutControl/ItemsStackPanelDemo.xaml ListView 的 ItemContainer 是 ListViewItem --> <ListView x:Name="listView" Margin="10 0 10 10" ItemContainerStyle="{StaticResource ListViewItemStyle}" SelectionMode="Multiple" ItemsSource="{x:Bind Employees}"> <ListView.ItemTemplate> <DataTemplate x:DataType="common:Employee"> <StackPanel Height="100" Width="100" Background="Blue"> <TextBlock x:Name="lblName" Text="{x:Bind Name}" /> <TextBlock x:Name="lblIsMale" Text="{x:Bind IsMale}" /> <!-- 這裡有個需求:當 ListViewItem 的 IsSelected 為 true 時顯示,反之則不顯示 此處的 TemplatedParent 是 ListViewItemPresenter,而不是 ListViewItem,所以需要 ListViewItemPresenter 中轉一下(ListViewItemPresenter 的 TemplatedParent 是 ListViewItem) 此處通過 Tag 屬性做中轉,如果 Tag 有別的用處的話,那麼就自己寫個附加屬性做中轉吧 如果以後 uwp 支持了 FindAncestor 的話,就可以不用中轉了,直接這樣寫就行了 {Binding Path=IsSelected, RelativeSource={RelativeSource Mode=FindAncestor, AncestorType={x:Type ListViewItem}}} --> <TextBlock x:Name="lblAge" Text="{x:Bind Age}" Visibility="{Binding Path=Tag, RelativeSource={RelativeSource Mode=TemplatedParent}, Converter={StaticResource BooleanToVisibilityConverter}}" /> </StackPanel> </DataTemplate> </ListView.ItemTemplate> </ListView> <!-- 通過 xaml 方式為 ListView 添加 item <ListView> <ListViewItem> <TextBlock Text="item1"/> </ListViewItem> <ListViewItem> <TextBlock Text="item2"/> </ListViewItem> <ListViewItem> <TextBlock Text="item3"/> </ListViewItem> </ListView> --> </Grid> </Page>
Controls/CollectionControl/ListViewBaseDemo/ListViewDemo.xaml.cs
/* * ListView - ListView 控制項(繼承自 ListViewBase, 請參見 /Controls/CollectionControl/ListViewBaseDemo/) */ using System.Collections.ObjectModel; using Windows.UI.Xaml.Controls; using Windows.UI.Xaml.Controls.Primitives; using Windows10.Common; namespace Windows10.Controls.CollectionControl { public sealed partial class ListViewDemo : Page { public ObservableCollection<Employee> Employees { get; set; } = new ObservableCollection<Employee>(TestData.GetEmployees()); public ListViewDemo() { this.InitializeComponent(); } } }
2、GridView 的示例
Controls/CollectionControl/ListViewBaseDemo/GridViewDemo.xaml
<Page x:Class="Windows10.Controls.CollectionControl.GridViewDemo" xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation" xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml" xmlns:local="using:Windows10.Controls.CollectionControl" xmlns:d="http://schemas.microsoft.com/expression/blend/2008" xmlns:mc="http://schemas.openxmlformats.org/markup-compatibility/2006" mc:Ignorable="d" xmlns:common="using:Windows10.Common"> <Page.Resources> <Style x:Key="GridViewItemStyle" TargetType="GridViewItem"> <Setter Property="Background" Value="Transparent"/> <Setter Property="Template"> <Setter.Value> <ControlTemplate TargetType="GridViewItem"> <!-- ListViewItemPresenter - GridViewItem 的 Presenter(繼承自 ContentPresenter, 請參見 /Controls/BaseControl/ContentControlDemo/ContentPresenterDemo.xaml) 預設樣式就是 generic.xaml 中的 <Style TargetType="GridViewItem"> 節點 如果需要自定義的話,那麼就在 generic.xaml 中的 <Style TargetType="GridViewItem" x:Key="GridViewItemExpanded"> 節點的基礎上修改 如果還不能滿足要求的話就通過繼承 ContentPresenter 來實現自定義的 ContentPresenter --> <ListViewItemPresenter Margin="10" SelectionCheckMarkVisualEnabled="True" SelectedBackground="Red" CheckBrush="Yellow" /> </ControlTemplate> </Setter.Value> </Setter> </Style> </Page.Resources> <Grid Background="Transparent"> <!-- GridView - GridView 控制項(繼承自 ListViewBase, 請參見 /Controls/CollectionControl/ListViewBaseDemo/) GridView 的預設佈局控制項是 ItemsWrapGrid,請參見 /Controls/CollectionControl/ItemsControlDemo/LayoutControl/ItemsWrapGridDemo.xaml GridView 的 ItemContainer 是 GridViewItem --> <GridView x:Name="gridView" Margin="10 0 10 10" ItemContainerStyle="{StaticResource GridViewItemStyle}" SelectionMode="Multiple" ItemsSource="{x:Bind Employees}"> <GridView.ItemTemplate> <DataTemplate x:DataType="common:Employee"> <StackPanel Height="100" Width="100" Background="Blue"> <TextBlock x:Name="lblName" Text="{x:Bind Name}" Foreground="Yellow" /> <TextBlock x:Name="lblAge" Text="{x:Bind Age}" Foreground="Aqua" /> <TextBlock x:Name="lblIsMale" Text="{x:Bind IsMale}" Foreground="Gray" /> </StackPanel> </DataTemplate> </GridView.ItemTemplate> </GridView> <!-- 通過 xaml 方式為 GridView 添加 item <GridView> <GridViewItem> <TextBlock Text="item1"/> </GridViewItem> <GridViewItem> <TextBlock Text="item2"/> </GridViewItem> <GridViewItem> <TextBlock Text="item3"/> </GridViewItem> </GridView> --> </Grid> </Page>
Controls/CollectionControl/ListViewBaseDemo/GridViewDemo.xaml.cs
/* * GridView - GridView 控制項(繼承自 ListViewBase, 請參見 /Controls/CollectionControl/ListViewBaseDemo/) */ using System.Collections.ObjectModel; using Windows.UI.Xaml.Controls; using Windows10.Common; namespace Windows10.Controls.CollectionControl { public sealed partial class GridViewDemo : Page { public ObservableCollection<Employee> Employees { get; set; } = new ObservableCollection<Employee>(TestData.GetEmployees()); public GridViewDemo() { this.InitializeComponent(); } } }
