ItemsPanelTemplate

用以定义集合控件的容器外观，如ListBox,Combox 等等
使用一个自定义的ListBox用以说明，其默认外观是上下排列，这里修改成横向排列

<Window.Resources>
    <DataTemplate x:Key="PersonDataTemplate">
        <Grid>
            <Grid.RowDefinitions>
                <RowDefinition Height="*"></RowDefinition>
                <RowDefinition Height="*"></RowDefinition>
            </Grid.RowDefinitions>
            <Grid.ColumnDefinitions>
                <ColumnDefinition Width="*"></ColumnDefinition>
                <ColumnDefinition Width="*"></ColumnDefinition>
            </Grid.ColumnDefinitions>
            <TextBlock Grid.Row="0" Grid.Column="0" Text="{Binding Name}"></TextBlock>
            <TextBlock Grid.Row="0" Grid.Column="1" Text="{Binding Age}"></TextBlock>
            <TextBlock Grid.Row="1" Grid.Column="0" Text="{Binding Hometown}"></TextBlock>
        </Grid>
    </DataTemplate>
    <ItemsPanelTemplate x:Key="PersonItemsPanelTemplate">
        <StackPanel Orientation="Horizontal" VerticalAlignment="Center" HorizontalAlignment="Center"></StackPanel>
    </ItemsPanelTemplate>
</Window.Resources>
<Grid>
    <ListBox ItemsSource="{Binding}" ItemTemplate="{StaticResource PersonDataTemplate}" ItemsPanel="{StaticResource PersonItemsPanelTemplate}"></ListBox>
