原文:WPF案例 (六) 动态切换UI布局
这个Wpf示例对同一个界面支持以ListView或者CardView的布局方式呈现界面,使用控件ItemsControl绑定数据源,使用DataTemplate为ItemsControl分别预定义了ListView和CardView的样式,在程序运行时,可在这两种Layout之间互相切换,界面如下。源代码在这里下载
为ItemsControl定义ListView UI布局的ItemTemplate,并指定MouseOver时DataTemplate的样式
ListView布局和样式
1 <DataTemplate x:Key="listViewDataTemplate">
2 <Border x:Name="listViewBorder" BorderThickness="0,0,0,1" Height="25"
3 BorderBrush="{StaticResource cardViewBackgroundBrush}" HorizontalAlignment="Stretch">
4 <StackPanel Orientation="Horizontal" HorizontalAlignment="Stretch">
5 <TextBlock VerticalAlignment="Top" Text="{Binding Path=BedNo}"
6 TextWrapping="Wrap" Margin="1,0,5,0" Width="20" FontSize="12" Foreground="Black" />
7 <TextBlock Text="{Binding Path=Name}" Grid.Row="0" Grid.Column="1"
8 TextWrapping="Wrap" Margin="1,0,5,0" VerticalAlignment="Top" Foreground="Black" FontSize="12" />
9 <TextBlock VerticalAlignment="Top" Text="{Binding Path=Sex}"
10 TextWrapping="Wrap" Margin="1,0,5,0" FontSize="12" Foreground="Black"/>
11 <TextBlock VerticalAlignment="Top" Text="{Binding Path=BirthDay}"
12 TextWrapping="Wrap" Margin="1,0,5,0" FontSize="12" Foreground="Black"/>
13 <TextBlock Text="{Binding Path=Address}" TextWrapping="Wrap"
14 Margin="1,0,5,0" FontSize="12" Foreground="Black" VerticalAlignment="Top"/>
15 <TextBlock Text="{Binding Path=City}" TextWrapping="Wrap"
16 Margin="1,0,5,0" FontSize="12" Foreground="Black" VerticalAlignment="Top"/>
17 <TextBlock Text="{Binding Path=PostCode}" TextWrapping="Wrap"
18 Margin="1,0,5,0" FontSize="12" Foreground="Black" VerticalAlignment="Top" HorizontalAlignment="Stretch"/>
19 <TextBlock Text="{Binding Path=HomePhoneNumber}" TextWrapping="Wrap"
20 Margin="1,0,5,0" FontSize="12" Foreground="Black" VerticalAlignment="Top"/>
21 </StackPanel>
22 </Border>
23 <DataTemplate.Triggers>
24 <Trigger Property="IsMouseOver" Value="True">
25 <Setter Property="Background" TargetName="listViewBorder" Value="{StaticResource cardViewBackgroundBrush}"/>
26 </Trigger>
27 </DataTemplate.Triggers>
28 </DataTemplate>
2 <Border x:Name="listViewBorder" BorderThickness="0,0,0,1" Height="25"
3 BorderBrush="{StaticResource cardViewBackgroundBrush}" HorizontalAlignment="Stretch">
4 <StackPanel Orientation="Horizontal" HorizontalAlignment="Stretch">
5 <TextBlock VerticalAlignment="Top" Text="{Binding Path=BedNo}"
6 TextWrapping="Wrap" Margin="1,0,5,0" Width="20" FontSize="12" Foreground="Black" />
7 <TextBlock Text="{Binding Path=Name}" Grid.Row="0" Grid.Column="1"
8 TextWrapping="Wrap" Margin="1,0,5,0" VerticalAlignment="Top" Foreground="Black" FontSize="12" />
9 <TextBlock VerticalAlignment="Top" Text="{Binding Path=Sex}"
10 TextWrapping="Wrap" Margin="1,0,5,0" FontSize="12" Foreground="Black"/>
11 <TextBlock VerticalAlignment="Top" Text="{Binding Path=BirthDay}"
12 TextWrapping="Wrap" Margin="1,0,5,0" FontSize="12" Foreground="Black"/>
13 <TextBlock Text="{Binding Path=Address}" TextWrapping="Wrap"
14 Margin="1,0,5,0" FontSize="12" Foreground="Black" VerticalAlignment="Top"/>
15 <TextBlock Text="{Binding Path=City}" TextWrapping="Wrap"
16 Margin="1,0,5,0" FontSize="12" Foreground="Black" VerticalAlignment="Top"/>
17 <TextBlock Text="{Binding Path=PostCode}" TextWrapping="Wrap"
18 Margin="1,0,5,0" FontSize="12" Foreground="Black" VerticalAlignment="Top" HorizontalAlignment="Stretch"/>
19 <TextBlock Text="{Binding Path=HomePhoneNumber}" TextWrapping="Wrap"
20 Margin="1,0,5,0" FontSize="12" Foreground="Black" VerticalAlignment="Top"/>
21 </StackPanel>
22 </Border>
23 <DataTemplate.Triggers>
24 <Trigger Property="IsMouseOver" Value="True">
25 <Setter Property="Background" TargetName="listViewBorder" Value="{StaticResource cardViewBackgroundBrush}"/>
26 </Trigger>
27 </DataTemplate.Triggers>
28 </DataTemplate>
为ItemsControl定义CardView UI布局的ItemTemplate,同时定义MouseOver时DataTemplate的样式
CardView布局和样式
