HeaderedContentControl模型

HeaderedContentControl类继承ContentControl类，表示带有Header的ContentControl，其除了具有ContentControl的Content属性外，还具有一个Header属性，Header的类型也是Object对象，与Content属性的用法类似。

从 HeaderedContentControl 继承的控件有：Expander、GroupBox、TabItem。

如定义一个带有图片和文字标题的Expander：
<Window x:Class="WpfApplication1.HeaderedContentControl模型"

    <Canvas>
        <Expander Margin="5" HorizontalAlignment="Center">
            <Expander.Header>
                <StackPanel Orientation="Horizontal">
                    <Image Source="image/7.jpg" Width="32" Height="32" />
                    <TextBlock Text="User Info" VerticalAlignment="Center" />

            </Expander.Header>
                <Expander.Content>
                <Grid>
                    <Grid.RowDefinitions>
