WPF窗体中选项卡与各个选项卡页面的分离

XAML代码：
// DemoViewer.xaml
<Window
    xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
    xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
    x:Class="BrawDraw.Com.Graphics.DemoViewer"
    Title="Drawing with Shapes">

   <DockPanel>
     <TabControl Background="White">
       <TabItem Header="Path">
         <Frame Background="White" Source="PathExample.xaml" />
       </TabItem>
       <TabItem Header="Polygon">
         <Frame Background="White" Source="PolygonExample.xaml" />
       </TabItem>
       <TabItem Header="Polyline">
         <Frame Background="White" Source="PolylineExample.xaml" />
       </TabItem>
       <TabItem Header="Rectangle">
         <Frame Background="White" Source="RectangleExample.xaml" />
       </TabItem>
     </TabControl>
   </DockPanel>
</Window>
这里使用了TabControl控件，每个选项卡使用TabItem, 然后再在其中的Frame标签中使用Source属性指定嵌入的Page页面。

相应的选项卡代码示例（为方便说明，仅举两例）：
（1）PolylineExample.xaml及C#代码：
详见： http://blog.csdn.net/johnsuna/archive/2007/10/19/1832994.aspx
（2）PathExample.xaml：
<Page
    xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
    xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
    x:Class="BrawDraw.Com.Graphics.PathExample"
    WindowTitle="Path Example">
<StackPanel>
  <Border>
    <Border.Background>
      <LinearGradientBrush StartPoint="0,0.5" EndPoint="1,0.5">
        <LinearGradientBrush.GradientStops>
          <GradientStop Color="#CCCCFF" Offset="0" />
          <GradientStop Color="AliceBlue" Offset="0.25" />
        </LinearGradientBrush.GradientStops>
      </LinearGradientBrush>
    </Border.Background>
    <TextBlock Margin="10" HorizontalAlignment="Left">
      Path Examples
    </TextBlock>
  </Border>   

  <StackPanel Margin="10">
   
    <Border Style="{StaticResource MyGridBorderStyle}">
      <Canvas Height="400" Width="400">
        <Path
          Data="M30,100 C 100,0 200,300 300,200 z"
          Fill="Blue"
          Stroke="Black"
          StrokeThickness="4" />

      </Canvas>
    </Border>

  </StackPanel>
</StackPanel>
</Page>

C#代码：
// PathExample.xaml.cs
using System;
using System.Windows;
using System.Windows.Controls;
using System.Windows.Documents;
using System.Windows.Navigation;
using System.Windows.Shapes;
using System.Windows.Media;
using System.Windows.Media.Animation;

namespace Microsoft.Samples.Graphics
{

    public partial class PathExample : Page
    {
        public PathExample()
        {
            InitializeComponent();
        }
    }
}

这里，选项卡的具体内容从Page继承（使用Page作为顶级标签）。
