在DataGrid中对数据进行分组 [英] Grouping data in a DataGrid

问题描述

我无法在DataGrid中对数据进行分组。经过一些研究，我了解到运行时的最后一分钟更改删除了GroupDescription和SortDescription属性;至少在XAML中。听起来它仍然可以通过代码隐藏起来。在我的项目中，我有

references 到System.Windows.Data和SystemComponentModel.DataAnotations。我无法添加对System.ComponentModel的引用，因为它不在列表中。在我的代码隐藏页面上，我有一个'using System.ComponentModel;'语句。当我尝试创建一个PagedCollectionView时，例如：

PagedCollectionView taskListView = new PagedCollectionView（taskList）;
taskListView.GroupDescriptions.Add（ new PropertyGroupDescription（ " State" ））;


我收到以下错误：

找不到类型或命名空间名称'PagedCollectionView'（您是否缺少using指令或程序集引用？）

如何做我参考这些我可以在DataGrid中对数据进行分组吗？另外，有没有人知道从XAML中删除这些内容的理由是什么。

I am having trouble grouping data in a DataGrid. After some research, I understand that there was a last minute change to the runtime that removed GroupDescription, and SortDescription properties; at least in XAML. It sounds like it is still possible via code behind. In my project, I have

references to Both System.Windows.Data, and SystemComponentModel.DataAnotations. I am unable to add a reference to System.ComponentModel as it is not in the list. On my code behind page, I have a 'using System.ComponentModel;' statement. When I try to create a PagedCollectionView such as:

PagedCollectionView taskListView = new PagedCollectionView(taskList);
taskListView.GroupDescriptions.Add(new PropertyGroupDescription("State"));


I get the following error:

The type or namespace name 'PagedCollectionView' could not be found (are you missing a using directive or an assembly reference?)

How do I reference these so I can group data in my DataGrid? Also, does anyone know what the rational was for removing these from the XAML.
