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>
