WPF datagrid automatic sorting by chosen column
提问by Marcin Zdunek
currently I am working on WPF's datagrid. I got an issue with automatic sorting. Here is my xaml:
目前我正在研究 WPF 的数据网格。我遇到了自动排序的问题。这是我的 xaml：
<DataGrid x:Name="customTasksDataGrid" Margin="10,10,10,38" Grid.Column="1" IsReadOnly="True" AutoGenerateColumns="False">
<DataGrid.Columns>
<DataGridTextColumn Header="ID" Binding="{Binding ID}"/>
<DataGridTextColumn Header="Client" Binding="{Binding Client.Names}"/>
...
<DataGridTextColumn Header="DueDate" Binding="{Binding DueDate, StringFormat=\{0:dd.MM.yy HH:mm\}}" SortDirection="Ascending">
<DataGridTextColumn.ElementStyle>
<Style TargetType="{x:Type TextBlock}">
<Setter Property="Foreground" Value="{Binding Path=., Converter={StaticResource converter}}"/>
</Style>
</DataGridTextColumn.ElementStyle>
</DataGridTextColumn>
...
</DataGrid.Columns>
The problem is: when I update my datagrid's ItemsSource, the datagrid is sorted by IDcolumn, not DueDateas desirable. How to implement autosorting by DueDatewhen any update action on my datagrid is performed?
问题是：当我更新我的数据网格的 ItemsSource 时，数据网格按ID列排序，而不是DueDate理想的。如何在DueDate对我的数据网格执行任何更新操作时实现自动排序？
I tried with: [ImplementPropertyChanged]tag from PropertyChanged.Fodyand put it before my CustomTaskclass, but this approach was not working at all ( don't even know if it is needed).
我尝试过：[ImplementPropertyChanged]标记 fromPropertyChanged.Fody并将其放在我的CustomTask课前，但这种方法根本不起作用（甚至不知道是否需要）。
EDIT:
编辑：
It can be done with:
可以通过以下方式完成：
customTasksDataGrid.ItemsSource = model;
customTasksDataGrid.Items.SortDescriptions.Add(new SortDescription("DueDate", ListSortDirection.Ascending));

You can simply sort the datagrid in Code Behind:
您可以简单地在代码隐藏中对数据网格进行排序：
datagrid.Items.SortDescriptions.Add(new SortDescription("DueDate", ListSortDirection.Ascending));
