private void ButtonBase_OnClick(object sender, RoutedEventArgs e)
{
    if (((sender as CheckBox)!).IsChecked!.Value)
        foreach (var item in ((grid1.DataContext as TrendDataSyncDialogViewModel)!).TrendTagCollection)
            item.IsSelected = true;
    else
        foreach (var item in ((grid1.DataContext as TrendDataSyncDialogViewModel)!).TrendTagCollection)
            item.IsSelected = false;
}

<DataGrid Name="grid1"  Grid.Row="1" hc:DataGridAttach.ShowRowNumber="True" hc:DataGridAttach.CanUnselectAllWithBlankArea="True"  HeadersVisibility="All" RowHeaderWidth="60" AutoGenerateColumns="False" ItemsSource="{Binding TrendTagCollection}">
            <DataGrid.Columns>
                <DataGridCheckBoxColumn  Width="80" CanUserResize="False" Binding="{Binding IsSelected}" >
                    <DataGridColumn.Header >
                        <CheckBox Name="CheckAll" Content="全选" Unchecked="ButtonBase_OnClick" Checked="ButtonBase_OnClick"  ></CheckBox>
                    </DataGridColumn.Header>
                </DataGridCheckBoxColumn>
                <DataGridTextColumn IsReadOnly="True" Width="180" CanUserResize="False" Binding="{Binding xxx}" Header="xxx"/>
                <DataGridTextColumn IsReadOnly="True" Width="*" CanUserResize="False" Binding="{Binding xxx}" Header="xxx"/>
                <DataGridTextColumn IsReadOnly="True" Width="80" CanUserResize="False" Binding="{Binding xxx}" Header="xxx"/>
                <DataGridTextColumn IsReadOnly="True" Width="80" CanUserResize="False" Binding="{Binding xxx}"   Header="xxx"/>
