1，View切换，效果呈现
- 视图1
- 视图2
- 视图3
2，在Xaml中添加Listview控件，Combobox控件。
<Grid >
<Grid.RowDefinitions>
<RowDefinition Height="143*"/>
<RowDefinition Height="30"/>
</Grid.RowDefinitions>
<ListView Grid.IsSharedSizeScope="True" x:Name="listview01" BorderBrush="Red" BorderThickness="2" ></ListView>
<StackPanel Grid.Row="1" Orientation="Horizontal">
<TextBlock Text="选择视图模式:" VerticalAlignment="Center"></TextBlock>
<ComboBox x:Name="combo01" SelectionChanged="combo01_Selected" MinWidth="150" VerticalContentAlignment="Center">
<sys:String>GirdView</sys:String>
<sys:String>ImageDetailView</sys:String>
<sys:String>ImageView</sys:String>
</ComboBox>
</StackPanel>
</Grid>3，自定义显示的视图。
[ContentProperty("ItemTemplate")]
/// <summary>
/// 自定义的显示视图
/// </summary>
public class TitleView : ViewBase
{
/// <summary>
/// ListViewItem数据模板，对应的是ListView的每一项
/// </summary>
public DataTemplate ItemTemplate
{
get; set;
}
/// <summary>
/// 选中时的背景颜色
/// </summary>
public Brush SelectedBackgroundBrush { get; set; } = new SolidColorBrush(Colors.Transparent);
/// <summary>
/// 选中时的前景颜色
/// </summary>
public Brush SelectedForegroundBrush { get; set; } = new SolidColorBrush(Colors.Black);
/// <summary>
/// ListView默认样式资源建，根据此键从Themes文件下资源字典Generic.xaml中获取默认的ListView样式
/// </summary>
protected override object DefaultStyleKey
{
get
{
//根据反射可知只要两个 public ComponentResourceKey(Type typeInTargetAssembly, object resourceId);
//中typeInTargetAssembly相同，resourceId相同则两个实例的hashcode相同，equal为 True 即两个实例相等
return new ComponentResourceKey(GetType(),"TitleView");
}
}
/// <summary>
/// ListViewItem默认样式资源键，根据此键从Themes文件下资源字典Generic.xaml中获取默认的ListViewItem样式
/// </summary>
protected override object ItemContainerDefaultStyleKey
{
get
{
return new ComponentResourceKey(GetType(),"TitleViewItem") ;
}
}
}- ListView.View:类型为ViewBase。
- ViewBase为抽象类，系统只有一个派生类：GridView。
- ListView.View用于表达ListViewItem中数据呈现的方式，在某一程度上可用ItemTemplate代替。
- 使用ComponentResourceKey指定资源而不是使用字符串指定资源。
4，定义默认样式。
- 同自定义无外观控件一样，其默认的样式也必须位于Themes文件夹下的资源字典Generic.xaml
<Style x:Key="{ComponentResourceKey TypeInTargetAssembly={x:Type local:TitleView} ,ResourceId=TitleViewItem}" TargetType="ListViewItem" >
<Setter Property="ContentTemplate" Value="{Binding RelativeSource={RelativeSource Mode=FindAncestor, AncestorType=ListView}, Path=View.ItemTemplate}"></Setter>
<!--<Setter Property="Grid.IsSharedSizeScope" Value="True"></Setter>-->
<Setter Property="Template">
<Setter.Value>
<ControlTemplate TargetType="ListViewItem">
<Border x:Name="Part_Border" Background="Transparent">
<ContentPresenter ></ContentPresenter>
</Border>
<ControlTemplate.Triggers>
<Trigger Property="IsSelected" Value="true">
<Setter TargetName="Part_Border" Property="Background" Value="{Binding RelativeSource={RelativeSource Mode=FindAncestor, AncestorType=ListView}, Path=View.SelectedBackgroundBrush}"></Setter>
<Setter Property="Foreground" Value="{Binding RelativeSource={RelativeSource Mode=FindAncestor, AncestorType=ListView}, Path=View.SelectedForegroundBrush}"></Setter>
</Trigger>
</ControlTemplate.Triggers>
</ControlTemplate>
</Setter.Value>
</Setter>
</Style>
<Style x:Key="{ComponentResourceKey TypeInTargetAssembly={x:Type local:TitleView} ,ResourceId=TitleView}" TargetType="ListView" >
<Setter Property="ItemsPanel">
<Setter.Value>
<ItemsPanelTemplate>
<WrapPanel></WrapPanel>
</ItemsPanelTemplate>
</Setter.Value>
</Setter>
<Setter Property="Template">
<Setter.Value>
<ControlTemplate TargetType="ListView">
<Border Margin="{TemplateBinding Margin}" BorderBrush="{TemplateBinding BorderBrush}" BorderThickness="{TemplateBinding BorderThickness}" CornerRadius="5" Background="{TemplateBinding Background}">
<ScrollViewer Margin="{TemplateBinding Padding}">
<ItemsPresenter></ItemsPresenter>
</ScrollViewer>
</Border>
</ControlTemplate>
</Setter.Value>
</Setter>
</Style>5，添加对象资源。
<Window.Resources>
<GridView x:Key="GirdView">
<GridViewColumn Header="Name" DisplayMemberBinding="{Binding ModelName}"></GridViewColumn>
<GridViewColumn Header="Model" DisplayMemberBinding="{Binding ModelNumber}"></GridViewColumn>
<GridViewColumn Header="Price" DisplayMemberBinding="{Binding UnitCost, StringFormat={}{0:C2}}"></GridViewColumn>
</GridView>
<local:TitleView x:Key="ImageDetailView" SelectedBackgroundBrush="LightGreen" SelectedForegroundBrush="Red">
<local:TitleView.ItemTemplate>
<DataTemplate>
<Border BorderBrush="SkyBlue" BorderThickness="2" Margin="5" Padding="5" CornerRadius="5">
<Grid >
<Grid.ColumnDefinitions>
<ColumnDefinition Width="auto">
</ColumnDefinition>
<ColumnDefinition Width="auto" SharedSizeGroup="c1"></ColumnDefinition>
</Grid.ColumnDefinitions>
<Image Margin="2" Width="100" Source="/Img/1.jpg" Stretch="Fill"></Image>
<StackPanel Grid.Column="1">
<TextBlock Text="{Binding ModelName}" FontSize="16" FontWeight="Bold"></TextBlock>
<TextBlock Text="{Binding ModelNumber}" ></TextBlock>
<TextBlock Text="{Binding UnitCost, StringFormat={}{0:C2}}" ></TextBlock>
</StackPanel>
</Grid>
</Border>
</DataTemplate>
</local:TitleView.ItemTemplate>
</local:TitleView>
<local:TitleView x:Key="ImageView" SelectedBackgroundBrush="LawnGreen" SelectedForegroundBrush="Blue">
<DataTemplate>
<Border BorderBrush="Chocolate" BorderThickness="2" Margin="3" Padding="5">
<StackPanel Width="100">
<Image Source="/Img/2.jpg" Stretch="Fill"></Image>
<TextBlock Text="{Binding ModelName}" TextWrapping="Wrap"></TextBlock>
</StackPanel>
</Border>
</DataTemplate>
</local:TitleView>
</Window.Resources>- 在GridView中的GridViewColumn既设置属性DisplayMember也设置属性CellTemplate，那么GridViewColumn将会使用DisplayMember而忽略CellTemplate。
6，代码
public partial class MainWindow : Window
{
public MainWindow()
{
InitializeComponent();
listview01.ItemsSource = DbStore.DAL.Factory.ProductsDal.QueryAll();
combo01.SelectedIndex = 0;
}
private void combo01_Selected(object sender, RoutedEventArgs e)
{
//获取选中的模式
string str = combo01.SelectedItem.ToString();
ViewBase view = this.Resources[str] as ViewBase;
listview01.View = view;
}
