WPF控件

1:内容控件(Content Controls)
2:条目控件(Items Controls)
3:文本控件(Text Controls)
4:范围控件(Range Controls)

一：内容控件
内容控件的最大的特征就是有一个Content属性，从前面的文章中，我们多多少少也知道Content接收的是一个Object类型，或许
我们会立即想到莫非Button就是一个内容控件，确实，Button算是一个内容控件，凡是内容控件都继承自ContentControl，因为
Content属性就是属于ContentControl。
<1>Button
<2>RepeatButton
一般用来实现“快进”，“快退”
Delay：作用就是按下时第一次触发Click的时间延迟。
Interval：每次click发生的时间间隔。

<Window x:Class="WpfApplication1.Window1"
        xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
        xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
        xmlns:sys="clr-namespace:System;assembly=mscorlib"
        xmlns:local="clr-namespace:WpfApplication1"
        Title="MainWindow" Height="350" Width="525">
    <Canvas>
        <TextBox Canvas.Left="151" Canvas.Top="69" Height="33" Name="textBox1" Width="172" Text="0" />
        <RepeatButton x:Name="test" Delay="100" Interval="100"  Click="test_Click" Width="172"
                      Content="确定" Height="61" Canvas.Left="151" Canvas.Top="121" />
    </Canvas>
</Window>

namespace WpfApplication1
{
    /// <summary>
    /// Window1.xaml 的交互逻辑
    /// </summary>
    public partial class Window1 : Window
    {
        public Window1()
        {
            InitializeComponent();
        }
        private void test_Click(object sender, RoutedEventArgs e)
        {
            var num = Convert.ToInt32(textBox1.Text);
            textBox1.Text = (++num).ToString();
        }
    }
}

<3>ToggleButton
从图中我们看到ToggleButton是CheckBox和RadioButton的基类。

<Window x:Class="WpfApplication1.Window1"
        xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
        xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
        xmlns:sys="clr-namespace:System;assembly=mscorlib"
        xmlns:local="clr-namespace:WpfApplication1"
        Title="MainWindow" Height="350" Width="525">
    <Grid>
        <CheckBox Content="CheckBox" Height="16" HorizontalAlignment="Left" Margin="96,137,0,0" Name="checkBox1"
                  VerticalAlignment="Top" IsThreeState="True" Indeterminate="checkBox1_Checked" />
    </Grid>
</Window>

namespace WpfApplication1
{
    /// <summary>
    /// Window1.xaml 的交互逻辑
    /// </summary>
    public partial class Window1 : Window
    {
        public Window1()
        {
            InitializeComponent();
        }

        private void checkBox1_Checked(object sender, RoutedEventArgs e)
        {
            MessageBox.Show("不错");
        }
    }
}

二：条目控件

条目控件首先都是继承自ItemsControl，在ItemsControl中我们发现有两个比较有意思的属性，Items和ItemsSource。
Items：
从图中可以看出Items属于ItemCollection的集合类型，所以每一个Item里面都可以放入一个Object类型对象，这里有意思的地方就是，
如果我放入的是一个UI元素，那么很好，wpf会调用UI的OnRender方法将UI元素呈现，如果说是一个没有OnRender方法的元素，那该
怎么办呢？wpf很智能，它会创建一个TextBlock，然后调用该对象的ToString()将字符串呈现在TextBlock上。
ItemsSource:
从前面文章中我们也看到，ItemsSource常用于数据绑定，所以是一个非常实用的属性。

<1>Expander
