容器里可以放很多控件,我们可以看XAML。
<UserControl x:Class="SilverlightApplication2.MainPage" xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation" xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml" xmlns:d="http://schemas.microsoft.com/expression/blend/2008" xmlns:mc="http://schemas.openxmlformats.org/markup-compatibility/2006" mc:Ignorable="d" d:DesignHeight="300" d:DesignWidth="400" xmlns:sdk="http://schemas.microsoft.com/winfx/2006/xaml/presentation/sdk"> <Grid x:Name="LayoutRoot" Background="White"> <sdk:Label Height="40" HorizontalAlignment="Left" Margin="88,210,0,0" Name="Label1" VerticalAlignment="Top" Width="207" /> <sdk:Label Height="32" HorizontalAlignment="Left" Margin="82,247,0,0" Name="Label2" VerticalAlignment="Top" Width="214" /> <StackPanel Height="66" HorizontalAlignment="Left" Margin="68,68,0,0" Name="StackPanel1" VerticalAlignment="Top" Width="272"> <TextBox Height="25" Name="TextBox1" Width="206" DataContext="{Binding}" Text="" /> <Button Content="确定" Height="22" Name="Button1" Width="183" /> </StackPanel> </Grid>
StackPanel就是一个容器
<StackPanel Height="66" HorizontalAlignment="Left" Margin="68,68,0,0" Name="StackPanel1" VerticalAlignment="Top" Width="272">
<TextBox Height="25" Name="TextBox1" Width="206" DataContext="{Binding}" Text="" />
<Button Content="确定" Height="22" Name="Button1" Width="183" />
</StackPanel>
从上面可以看出来有2个控件在容器里,TextBox和Button
因为一个控件里可以包括多个属性,比如:
<Button Height="22" Name="Button1" Width="183">
<Button.Content>
确定
</Button.Content>
</Button>
但一个控件需要包括多个控件,必须是容器。
