在DataGrid中对数据进行分组能辨析数据的内部信息，反映数据间的依存关系。本文将为大家介绍如何在DataGrid中实施数据的分组。

**需要了解的知识**

**1****）PagedCollectionView**

它代表了一个有关分组、排序、筛选和导航的分页数据集合。

**2****）PagedCollectionView的GroupDescriptions属性**

对分组信息的描述，用于绑定需要分组的字段。

**3****）DataGrid的RowGroupHeaderStyles属性**

用于设置分组标签头的样式。

**实例**

详细的说明在代码注释中给出。

**MainPage.xaml****文件代码：**

<UserControl

xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"

xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"

xmlns:d="http://schemas.microsoft.com/expression/blend/2008" xmlns:mc="http://schemas.openxmlformats.org/markup-compatibility/2006"

mc:Ignorable="d" xmlns:data="clr-namespace:System.Windows.Controls;assembly=System.Windows.Controls.Data" x:Class="SilverlightClient.MainPage"

d:DesignWidth="320" d:DesignHeight="480">

<data:DataGrid x:Name="dgEmployee" Margin="8,8,8,52" FontSize="14" AutoGenerateColumns="False">

<data:DataGrid.RowGroupHeaderStyles>

</Style>

</Style>

</data:DataGrid.RowGroupHeaderStyles>

<data:DataGrid.Columns>

<data:DataGridTextColumn Header="工号" Binding="\{ Binding EmployeeID\}"/>

<data:DataGridTextColumn Header="姓名" Binding="\{ Binding EmployeeName\}"/>

<data:DataGridTextColumn Header="年龄" Binding="\{ Binding EmployeeAge\}"/>

<data:DataGridTextColumn Header="部门" Binding="\{ Binding DepartmentName\}"/>

<data:DataGridTextColumn Header="级别" Binding="\{ Binding Level\}"/>

</data:DataGrid.Columns>

</data:DataGrid>

</Grid>

</UserControl>

**MainPage.xaml.cs****文件代码：**

using System;

using System.Collections.Generic;

using System.Linq;

using System.Net;

using System.Windows;

using System.Windows.Controls;

using System.Windows.Documents;

using System.Windows.Input;

using System.Windows.Media;

using System.Windows.Media.Animation;

using System.Windows.Shapes;

using System.Windows.Data;

using System.ComponentModel;

namespace SilverlightClient

public class Employees

public int EmployeeID \{ get; set; \}

public string EmployeeName \{ get; set; \}

public int EmployeeAge \{ get; set; \}

public string DepartmentName \{ get; set; \}

public string Level \{ get; set; \}

public partial class MainPage : UserControl

public MainPage()

InitializeComponent();

this.Loaded += new RoutedEventHandler(MainPage\_Loaded);

public List<Employees> GetEmployees()

List<Employees> returnedValue = new List<Employees>();

returnedValue.Add(new Employees() \{ EmployeeID = 1, EmployeeName = "张三", EmployeeAge = 23, DepartmentName = "财务部", Level = "初级" \});

returnedValue.Add(new Employees() \{ EmployeeID = 2, EmployeeName = "李四", EmployeeAge = 24, DepartmentName = "财务部", Level = "中级" \});

returnedValue.Add(new Employees() \{ EmployeeID = 3, EmployeeName = "王五", EmployeeAge = 25, DepartmentName = "管理部", Level = "中级" \});

returnedValue.Add(new Employees() \{ EmployeeID = 4, EmployeeName = "赵六", EmployeeAge = 26, DepartmentName = "管理部", Level = "初级" \});

returnedValue.Add(new Employees() \{ EmployeeID = 5, EmployeeName = "钱七", EmployeeAge = 27, DepartmentName = "工程部", Level = "中级" \});

returnedValue.Add(new Employees() \{ EmployeeID = 6, EmployeeName = "孙八", EmployeeAge = 28, DepartmentName = "工程部", Level = "初级" \});

returnedValue.Add(new Employees() \{ EmployeeID = 7, EmployeeName = "小赵", EmployeeAge = 26, DepartmentName = "财务部", Level = "中级" \});

returnedValue.Add(new Employees() \{ EmployeeID = 8, EmployeeName = "小钱", EmployeeAge = 28, DepartmentName = "财务部", Level = "高级" \});

return returnedValue;

void MainPage\_Loaded(object sender, RoutedEventArgs e)

PagedCollectionView pcv = new PagedCollectionView(GetEmployees());

pcv.GroupDescriptions.Add(new PropertyGroupDescription("DepartmentName"));//添加分组信息描述

pcv.GroupDescriptions.Add(new PropertyGroupDescription("Level"));

dgEmployee.ItemsSource = pcv;
