Silverlight 4.0 将UI元素依赖项属性与类的数据成员绑定

我需要用类中定义的bool值绑定StackPannel中的所有复选框（IsChecked属性）。附加我的Xaml和我的问题，请帮助

    <!--ContentPanel - place additional content here-->
    <Grid x:Name="ContentPanel" Grid.Row="1" Margin="12,0,12,0">
        <StackPanel Height="287" HorizontalAlignment="Left" Margin="78,65,0,0" Name="stackPanel1" VerticalAlignment="Top" Width="309" DataContext="checkFlag">
            <CheckBox Content="" Height="71" Name="checkBox1" IsChecked="{Binding Path=Binding.MainPage,Source=checkFlag,Mode=TwoWay}"/>
            <CheckBox Content="" Height="71" Name="checkBox2" IsChecked="{Binding Path=Binding.MainPage,Source=checkFlag,Mode=TwoWay}"/>
        </StackPanel>
        <Button Content="Button" Height="72" HorizontalAlignment="Left" Margin="78,400,0,0" Name="button1" VerticalAlignment="Top" Width="160" Click="button1_Click" />
        <Button Content="Button" Height="72" HorizontalAlignment="Left" Margin="227,400,0,0" Name="button2" VerticalAlignment="Top" Width="160" Click="button2_Click" />

    <!--ContentPanel - place additional content here-->
    <Grid x:Name="ContentPanel" Grid.Row="1" Margin="12,0,12,0">
        <StackPanel Height="287" HorizontalAlignment="Left" Margin="78,65,0,0" Name="stackPanel1" VerticalAlignment="Top" Width="309" DataContext="checkFlag">
            <CheckBox Content="" Height="71" Name="checkBox1" IsChecked="{Binding Path=Binding.MainPage,Source=checkFlag,Mode=TwoWay}"/>
            <CheckBox Content="" Height="71" Name="checkBox2" IsChecked="{Binding Path=Binding.MainPage,Source=checkFlag,Mode=TwoWay}"/>
        </StackPanel>
        <Button Content="Button" Height="72" HorizontalAlignment="Left" Margin="78,400,0,0" Name="button1" VerticalAlignment="Top" Width="160" Click="button1_Click" />
        <Button Content="Button" Height="72" HorizontalAlignment="Left" Margin="227,400,0,0" Name="button2" VerticalAlignment="Top" Width="160" Click="button2_Click" />

在我看来，您需要实现，正如您所猜测的，

INotifyPropertyChanged

这里有一个链接

    <!--ContentPanel - place additional content here-->
    <Grid x:Name="ContentPanel" Grid.Row="1" Margin="12,0,12,0">
        <StackPanel Height="287" HorizontalAlignment="Left" Margin="78,65,0,0" Name="stackPanel1" VerticalAlignment="Top" Width="309" DataContext="checkFlag">
            <CheckBox Content="" Height="71" Name="checkBox1" IsChecked="{Binding Path=Binding.MainPage,Source=checkFlag,Mode=TwoWay}"/>
            <CheckBox Content="" Height="71" Name="checkBox2" IsChecked="{Binding Path=Binding.MainPage,Source=checkFlag,Mode=TwoWay}"/>
        </StackPanel>
        <Button Content="Button" Height="72" HorizontalAlignment="Left" Margin="78,400,0,0" Name="button1" VerticalAlignment="Top" Width="160" Click="button1_Click" />
        <Button Content="Button" Height="72" HorizontalAlignment="Left" Margin="227,400,0,0" Name="button2" VerticalAlignment="Top" Width="160" Click="button2_Click" />

下面是一些演示代码

    <!--ContentPanel - place additional content here-->
    <Grid x:Name="ContentPanel" Grid.Row="1" Margin="12,0,12,0">
        <StackPanel Height="287" HorizontalAlignment="Left" Margin="78,65,0,0" Name="stackPanel1" VerticalAlignment="Top" Width="309" DataContext="checkFlag">
            <CheckBox Content="" Height="71" Name="checkBox1" IsChecked="{Binding Path=Binding.MainPage,Source=checkFlag,Mode=TwoWay}"/>
            <CheckBox Content="" Height="71" Name="checkBox2" IsChecked="{Binding Path=Binding.MainPage,Source=checkFlag,Mode=TwoWay}"/>
        </StackPanel>
        <Button Content="Button" Height="72" HorizontalAlignment="Left" Margin="78,400,0,0" Name="button1" VerticalAlignment="Top" Width="160" Click="button1_Click" />
        <Button Content="Button" Height="72" HorizontalAlignment="Left" Margin="227,400,0,0" Name="button2" VerticalAlignment="Top" Width="160" Click="button2_Click" />

public class MyData : INotifyPropertyChanged
{

   public event PropertyChangedEventHandler PropertyChanged;

   protected void RaisePropertyChanged(string property)
   {
      PropertyChangedEventArgs args = new PropertyChangedEventArgs(property);
      var handler = this.PropertyChanged;
      if (handler != null)
      {
      handler(this, args);
      }
   }

   int _someInt = 0;
   public int SomeInt
   {
      get { return _someInt ;}
      set { if ( value == _someInt  ) return;
            _someInt = value;
            RaisePropertyChanged("SomeInt");
          }
   }

   string _someString = string.Empty;
   public string SomeString 
   {
      get { return _someString ;}
      set { if ( value == _someString ) return;
            _someString = value;
            RaisePropertyChanged("SomeString ");
          }
   }

}

设置私有变量，然后为每个要公开的变量添加属性。

在getter中，只需返回值。。。在setter中，检查值是否已更改，如果已更改，则分配值并引发属性更改事件。确保以字符串形式传入的名称与属性相同。。。相同的大写字母，相同的拼写，等等。

那么到底是什么问题呢？感谢您宝贵的回答，但正如您给出的示例和其他各种示例一样，DependencyProperty始终是string类型。如何将其与其他类型一起使用？？？？
