wpf datagrid隐藏满足条件的行 RRS feed


  • 您好 zhang_zi_jing,

    >>"如果选择的行对应的数据源项目的A属性为a, 那么隐藏, 如何实现?"

    如果您想要隐藏DataGrid的某些行, 最好的方法是对数据源做筛选,然后再重新绑定数据源到DataGrid控件上。另外一种方法是使用出发器动态的设定行的Visibility属性。这里需要写一个绑定转换器,以下代码供你参考。

        <Style TargetType="{x:Type DataGridRow}">
                <DataTrigger Binding="{Binding A, Converter={StaticResource hiddenConverter}}" Value="True">
                    <Setter Property="Visibility" Value="Collapsed"/>
    public class HiddenConverter : IValueConverter
        public object Convert(object value, Type targetType, object parameter, CultureInfo culture)
            if (value != null && value.ToString() == "a")
                return Visibility.Collapsed;
                return Visibility.Visible;
        public object ConvertBack(object value, Type targetType, object parameter, CultureInfo culture)
            throw new NotImplementedException();
