WPF DataGrid DataGridTextColumn

Style设置时，无法绑定到数据，需要这样写

 1 <DataGridTextColumn Header="呵呵"  Binding="{Binding ID}" >
 2                     <DataGridTextColumn.ElementStyle>
 3                         <Style TargetType="TextBlock">
 4                             <Setter Property="Visibility" Value="{Binding ElementName=WW,Path=DataContext.Visi}" />
 5                         </Style>
 6                     </DataGridTextColumn.ElementStyle>
 7                     <DataGridTextColumn.HeaderStyle>
 8                         <Style TargetType="DataGridColumnHeader">
 9                             <Setter Property="Visibility" Value="{Binding ElementName=WW,Path=DataContext.Visi}" />
10                         </Style>
11                     </DataGridTextColumn.HeaderStyle>
12                     <DataGridTextColumn.CellStyle>
13                         <Style TargetType="DataGridCell">
14                             <Setter Property="Visibility" Value="{Binding ElementName=WW,Path=DataContext.Visi}" />
15                         </Style>
16                     </DataGridTextColumn.CellStyle>
17                 </DataGridTextColumn>
