如何按所选列对 ListView 进行排序？

Question

源线程：如何使用不同的 dataTemplate （int， bool， string， ...） 对列表视图进行排序，由 Alex Li-MSFT 回答。

我有一个 ListView 控件，当用户单击特定列标题时，我想对列表中的所有项目进行排序，如何实现它？

这是我的 XAML 代码：

<ListView ItemsSource="{Binding}" x:Name="listViewControl">  
  
  <ListView.View>  
    <GridView AllowsColumnReorder="True">  
        
      <GridViewColumn>  
        <GridViewColumn.CellTemplate>  
          <DataTemplate>  
            <TextBlock Text="{Binding Path=SomeInteger}"/>  
          </DataTemplate>  
        </GridViewColumn.CellTemplate>  
      </GridViewColumn>  
  
      <GridViewColumn>  
        <GridViewColumn.CellTemplate>  
          <DataTemplate>  
            <TextBlock Text="{Binding Path=SomeString}"/>  
          </DataTemplate>  
        </GridViewColumn.CellTemplate>  
      </GridViewColumn>  
  
      <GridViewColumn>  
        <GridViewColumn.CellTemplate>  
          <DataTemplate>  
            <CheckBox  IsChecked="{Binding SomeBool}"/>  
          </DataTemplate>  
        </GridViewColumn.CellTemplate>  
      </GridViewColumn>  
  
      <GridViewColumn Header="Category" Width="120">  
        <GridViewColumn.CellTemplate>  
          <DataTemplate>  
            <ComboBox ItemsSource="{Binding ElementName=mainWindow, Path=StringList}"  
                      SelectedItem="{Binding Path=SomeString}"/>  
          </DataTemplate>  
        </GridViewColumn.CellTemplate>  
      </GridViewColumn>  
  
</ListView>

你好

欢迎来到我们的 Microsoft 问答平台！

您可以使用我的演示：

 public partial class MainWindow : Window  
    {  
        ObservableCollection<MyClass> list = new ObservableCollection<MyClass>();  
        public MainWindow()  
        {  
            InitializeComponent();  
            list.Add(new MyClass() { SomeBool = false, SomeInteger = 1, SomeString = "3" });  
            list.Add(new MyClass() { SomeBool = false, SomeInteger = 2, SomeString = "2" });  
            list.Add(new MyClass() { SomeBool = true, SomeInteger = 3, SomeString = "3" });  
            this.DataContext = list;  
        }  
  
        private void ListViewControl_Click(object sender, RoutedEventArgs e)  
        {  
              
            if (e.OriginalSource is GridViewColumnHeader)  
            {  
  
                GridViewColumn clickedColumn = (e.OriginalSource as GridViewColumnHeader).Column;  
              
                string bindingProperty=null;  
                if (clickedColumn != null)  
                {  
                    if (clickedColumn.Header.ToString() == "column1")  
                    {  
                         bindingProperty = "SomeInteger";  
                    }  
                    if (clickedColumn.Header.ToString() == "column2")  
                    {  
                        bindingProperty = "SomeString";  
                    }  
                    if (clickedColumn.Header.ToString() == "column3")  
                    {  
                        bindingProperty = "SomeBool";  
                    }  
                    SortDescriptionCollection sdc = listViewControl.Items.SortDescriptions;  
                    ListSortDirection sortDirection = ListSortDirection.Ascending;  
                    if (sdc.Count > 0)  
                    {  
                        SortDescription sd = sdc[0];  
                        sortDirection = (ListSortDirection)((((int)sd.Direction) + 1) % 2);  
                        sdc.Clear();  
                    }  
                    sdc.Add(new SortDescription(bindingProperty, sortDirection));  
                }  
            }  
        }  
         
    }  
      
    
    public class MyClass  
    {  
        public int SomeInteger { get; set; }  
        public string SomeString { get; set; }  
        public bool SomeBool { get; set; }  
    }  

xaml：

<Grid>  
        <ListView  ItemsSource="{Binding}"  x:Name="listViewControl" GridViewColumnHeader.Click="ListViewControl_Click">  
  
            <ListView.View>  
                <GridView AllowsColumnReorder="True">  
  
                    <GridViewColumn Header="column1" >  
                        <GridViewColumn.CellTemplate>  
                            <DataTemplate>  
                                <TextBlock Text="{Binding Path=SomeInteger}" />  
                            </DataTemplate>  
                        </GridViewColumn.CellTemplate>  
                    </GridViewColumn>  
  
                    <GridViewColumn Header="column2">  
                        <GridViewColumn.CellTemplate>  
                            <DataTemplate>  
                                <TextBlock Text="{Binding Path=SomeString}"/>  
                            </DataTemplate>  
                        </GridViewColumn.CellTemplate>  
                    </GridViewColumn>  
  
                    <GridViewColumn Header="column3">  
                        <GridViewColumn.CellTemplate>  
                            <DataTemplate>  
                                <CheckBox  IsChecked="{Binding SomeBool}"/>  
                            </DataTemplate>  
                        </GridViewColumn.CellTemplate>  
                    </GridViewColumn>  
  
                    <GridViewColumn Header="Category" Width="120">  
                        <GridViewColumn.CellTemplate>  
                            <DataTemplate>  
                                <ComboBox ItemsSource="{Binding ElementName=mainWindow, Path=StringList}"  
                      SelectedItem="{Binding Path=SomeString}"/>  
                            </DataTemplate>  
                        </GridViewColumn.CellTemplate>  
  
                    </GridViewColumn>  
                    </GridView>  
            </ListView.View>  
        </ListView>  
    </Grid>
