试试这个：

   <CheckBox x:Name="chkSelectAll" Content="Select All" />
   <CheckBox x:Name="chkjon" Content="Jon" IsChecked="{Binding IsChecked,ElementName=chkSelectAll,Mode=OneWay}" />
   <CheckBox x:Name="chkbob" Content="Bob"  IsChecked="{Binding IsChecked,ElementName=chkSelectAll,Mode=OneWay}" />
   <CheckBox x:Name="chkmary" Content="Mary"  IsChecked="{Binding IsChecked,ElementName=chkSelectAll,Mode=OneWay}" />
