WPF 用 DataTemplate  合并DataGrid列表列头<类似报表设计>及行头列头样式 - 学习

1.新建一个WPF项目WpfApplication1,新建一个窗体DataGridTest,前台代码如下:

<Window x:Class="WpfApplication1.DataGridTest"
        xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
        xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
        Title="DataGridTest" Height="300" Width="300">
    <Window.Resources>

<!-- 列头的背景色样式 -->
        <Style x:Key="CityNumStyle" TargetType="DataGridColumnHeader">
            <Setter Property="Template">
                <Setter.Value>
                    <ControlTemplate>
                        <Grid x:Name="Root">
                            <!--<Rectangle x:Name="BackgroundGradient" Fill="#eee" Stretch="Fill" Grid.ColumnSpan="2" />-->
                            <ContentPresenter Content="区号" Grid.Row="2" VerticalAlignment="Center" HorizontalAlignment="Center" />
                        </Grid>
                    </ControlTemplate>
                </Setter.Value>
            </Setter>
        </Style>

<!-- 合并列头的样式模版 -->

<Style x:Key="CityNameStyle" TargetType="DataGridColumnHeader">
            <Setter Property="Foreground" Value="#222" />
            <Setter Property="HorizontalContentAlignment" Value="Left" />
            <Setter Property="VerticalContentAlignment" Value="Center" />
            <Setter Property="IsTabStop" Value="False" />
            <Setter Property="SeparatorBrush" Value="#CCC" />
            <Setter Property="Padding" Value="8" />
            <Setter Property="Template">
                <Setter.Value>
                    <ControlTemplate>
                        <Grid x:Name="Root">
                            <Grid.ColumnDefinitions>
                                <ColumnDefinition />
                                <ColumnDefinition Width="auto" />
                            </Grid.ColumnDefinitions>
                            <!--<Rectangle x:Name="BackgroundRectangle" Fill="#eee" Stretch="Fill" Grid.ColumnSpan="2" />-->
                            <Grid HorizontalAlignment="{TemplateBinding HorizontalContentAlignment}" VerticalAlignment="{TemplateBinding VerticalContentAlignment}">
                                <Grid.RowDefinitions>
                                    <RowDefinition Height="20" />
                                    <RowDefinition Height="1" />
                                    <RowDefinition Height="20" />
                                </Grid.RowDefinitions>
                                <Grid.ColumnDefinitions>
                                    <ColumnDefinition Width="100" />
                                    <ColumnDefinition Width="1" />
                                    <ColumnDefinition Width="100" />
                                </Grid.ColumnDefinitions>
                                <!--设置标题名称-->
                                <ContentPresenter Content="省份城市" VerticalAlignment="Center" HorizontalAlignment="Center" Grid.ColumnSpan="3" />
                                <!--设置间隔线-->
                                <Rectangle Fill="#ccc" VerticalAlignment="Stretch" Height="1" Visibility="Visible" Grid.Row="1" Grid.ColumnSpan="3" />
                                <ContentPresenter Content="省名" Grid.Row="2" VerticalAlignment="Center" HorizontalAlignment="Center" />
                                <Rectangle Fill="#ccc" VerticalAlignment="Stretch" Width="1" Visibility="Visible" Grid.Row="2" Grid.Column="1" />
                                <ContentPresenter Content="城市" Grid.Row="2" Grid.Column="2" VerticalAlignment="Center" HorizontalAlignment="Center" />
                            </Grid>
                            <Rectangle x:Name="VerticalSeparator" Fill="#ccc" VerticalAlignment="Stretch" Width="1" Visibility="Visible" Grid.Row="1" Grid.Column="1" />
                        </Grid>
                    </ControlTemplate>
                </Setter.Value>
            </Setter>
        </Style>
    </Window.Resources>

<Grid Margin="5">
        <DataGrid AutoGenerateColumns="False" HorizontalAlignment="Stretch" Name="dataGrid1"
                  FrozenColumnCount="0" HeadersVisibility="All" HorizontalGridLinesBrush="Red" RowBackground="AliceBlue">
            <DataGrid.ColumnHeaderStyle>

<!-- 列头的背景色样式 -->
                <Style TargetType="DataGridColumnHeader">
                    <Setter Property="Background">
                        <Setter.Value>
                            <LinearGradientBrush StartPoint="0,0" EndPoint="0,1">
                                <GradientStop Color="White" Offset="0"/>
                                <GradientStop Color="LightGray" Offset="0.5"/>
                                <GradientStop Color="White" Offset="1"/>
                            </LinearGradientBrush>
                        </Setter.Value>
                    </Setter>
                    <Setter Property="Foreground" Value="Black"/>
                    <Setter Property="FontSize" Value="13" />
                </Style>
            </DataGrid.ColumnHeaderStyle>
             <DataGrid.RowHeaderStyle>

                <!-- 行头的背景色样式 -->
                <Style TargetType="DataGridRowHeader">
                    <Setter Property="Content" Value="*"/>
                    <Setter Property="Width" Value="10"/>
                    <Setter Property="Background">
                        <Setter.Value>
                            <LinearGradientBrush StartPoint="0,0" EndPoint="1,1">
                                <GradientStop Color="White" Offset="0"/>
                                <GradientStop Color="SkyBlue" Offset="1"/>
                            </LinearGradientBrush>
                        </Setter.Value>
                    </Setter>
                    <Style.Triggers>
                        <Trigger Property="IsMouseOver" Value="True">
                            <Setter Property="ToolTip" Value="选中该行"/>
                        </Trigger>
                    </Style.Triggers>
                </Style>
            </DataGrid.RowHeaderStyle>
            <DataGrid.Columns>
                <DataGridTemplateColumn Header="sec" HeaderStyle="{StaticResource CityNameStyle}">
                    <DataGridTemplateColumn.CellTemplate>
                        <DataTemplate>
                            <StackPanel Orientation="Horizontal">
                                <Label Content="{Binding AddrName}" Width="100" />
                                <Rectangle Fill="#000" VerticalAlignment="Stretch" Margin="0" Width="1" />
                                <Label Content="{Binding CityName}" Width="100" />
                            </StackPanel>
                        </DataTemplate>
                    </DataGridTemplateColumn.CellTemplate>
                </DataGridTemplateColumn>
                <DataGridTextColumn HeaderStyle="{StaticResource CityNumStyle}" Binding="{Binding TelNum}" Width="100" />
                <DataGridTextColumn Header="统计" Binding="{Binding TotalSum}" Width="100" />
            </DataGrid.Columns>
        </DataGrid>
    </Grid>
    </Window>

2.后台CS文件代码如下:

using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using System.Windows;
using System.Windows.Controls;
using System.Windows.Data;
using System.Windows.Documents;
using System.Windows.Input;
using System.Windows.Media;
using System.Windows.Media.Imaging;
using System.Windows.Shapes;

namespace WpfApplication1

{
    /// <summary>
    /// DataGridTest.xaml 的交互逻辑
    /// </summary>
    public partial class DataGridTest : Window
    {
        public DataGridTest()
        {
            InitializeComponent();
            this.dataGrid1.ItemsSource = CityInfo.GetInfo();
        }
    }

//定义绑定DataGrid的实体和集合
    public class CityInfo
    {
        public string AddrName { get; set; }
        public string CityName { get; set; }
        public string TelNum { get; set; }
        public double TotalSum { get; set; }
        public static List<CityInfo> GetInfo()
        {
            return new List<CityInfo>()
            {
                new CityInfo() { AddrName="湖北", CityName = "武汉", TelNum="123", TotalSum = 1.23 },
                new CityInfo() { AddrName="广东", CityName = "广州", TelNum="234", TotalSum = 1.23 },
                new CityInfo() { AddrName="广西", CityName = "南宁", TelNum="0152", TotalSum = 1.23 },
                new CityInfo() { AddrName="湖南", CityName = "长沙", TelNum="0123", TotalSum = 1.23 },
                new CityInfo() { AddrName="江西", CityName = "南昌", TelNum="123", TotalSum = 10.23 }
            };
        }
    }
}
