WPF中ListView排序实现

要实现ListView点击某一列进行排序，需要处理列点击事件 

<Window x:Class="ListViewSort.MainWindow"
    xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
    xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
    Title="MainWindow" Height="300" Width="300" Loaded="Window_Loaded">
    <Grid>
        <ListView GridViewColumnHeader.Click="GridViewColumnHeader_Click" Margin="2" ItemsSource="{Binding Path=DataList}" >
            <ListView.View>
                <GridView>
                    <GridViewColumn  Header="ID" DisplayMemberBinding="{Binding ID}" />
                    <GridViewColumn  Header="Name" DisplayMemberBinding="{Binding Name}" />
                </GridView>
            </ListView.View>
        </ListView>
    </Grid>
</Window>

下面的代码支持ListView 多个列点击排序，并会记住点击过的每个列的排序方向 。

 private void GridViewColumnHeader_Click(object sender, RoutedEventArgs e) {
            ListView view = sender as ListView;
            if (view == null) {
                return;
            }
            if (e.OriginalSource is GridViewColumnHeader) {
                //获取点击列
                GridViewColumn clickedColumn = (e.OriginalSource as GridViewColumnHeader)?.Column;
                if (clickedColumn != null) {
                    //获取该列绑定的属性
                    string bindingProperty = (clickedColumn.DisplayMemberBinding as Binding)?.Path.Path;
                    if (bindingProperty == null) {
                        return;
                    }
                    SortDescriptionCollection sdc = view.Items.SortDescriptions;
                    ListSortDirection sortDirection = ListSortDirection.Ascending;
                    foreach (var sd in sdc) {
                        if (sd.PropertyName.Equals(bindingProperty)) {
                            //改变排序方向
                            sortDirection = (ListSortDirection) ((((int) sd.Direction) + 1) % 2);
                            //取得排序方向后，删除当前的SortDescription
                            sdc.Remove(sd);
                            break;
                        }
                    }
                    //添加新的SortDescription到SortDescriptions首位，使之生效
                    sdc.Insert(0,new SortDescription(bindingProperty, sortDirection));
                }
            }
        }

排序是根据列的类型来的，就ID列来说，int类型的排序结果是2，3，17，而如果你把该列
类型改为string，结果就会是17,2,3，如果你定义列的时候不加类型，默认是string，如
果是自定义类型，那么请继承IComparable接口，实现CompareTo方法。
