WPF之TabControl控件用法

先创建实体基类：NotificationObject(用来被实体类继承) 实现属性更改通知接口：

using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using System.ComponentModel;

namespace TabControlDemo
{
    public class NotificationObject:INotifyPropertyChanged
    {
        public event PropertyChangedEventHandler PropertyChanged;

        public void OnPropertyChanged(string propertyName)
        {
            if (this.PropertyChanged!=null)
            {
                this.PropertyChanged.Invoke(this, new PropertyChangedEventArgs(propertyName));
            }
        }
    }
}

创建员工类Employee继承NotificationObject类：

using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;

namespace TabControlDemo
{
    public class Employee:NotificationObject
    {
        private string employeeName;

        public string EmployeeName
        {
            get { return employeeName; }
            set
            {
                if (value!=employeeName)
                {
                    employeeName = value;
                    OnPropertyChanged("EmployeeName");
                }
            }
        }

        private string sex;

        public string Sex
        {
            get { return sex; }
            set
            {
                if (value != sex)
                {
                    sex = value;
                    OnPropertyChanged("Sex");
                }
            }
        }

        private int age;

        public int Age
        {
            get { return age; }
            set
            {
                if (value != age)
                {
                    age = value;
                    OnPropertyChanged("Age");
                }
            }
        }

        private string title;

        public string Title
        {
            get { return title; }
            set
            {
                if (value != title)
                {
                    title = value;
                    OnPropertyChanged("Title");
                }
            }
        }
    }
}

创建部门类Department继承NotificationObject类：

using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using System.Collections.ObjectModel;

namespace TabControlDemo
{
   public class Department:NotificationObject
    {
        private string name;

        public string Name
        {
            get { return name; }
            set 
            {
                if (value!=name)
                {
                    name = value;
                    OnPropertyChanged("Name");
                }
            }
        }

        private ObservableCollection<Employee> employees;

        public ObservableCollection<Employee> Employees
        {
            get 
            {
                if (employees==null)
                {
                    employees = new ObservableCollection<Employee>();
                }
                return employees;
            }

        }
        
    }
}

主窗口的XAML头部引用名称空间：

xmlns:local="clr-namespace:TabControlDemo"

本例中TabControl控件中的TabItem用DataGrid控件来显示数据，

主窗口的资源中定义DataGridCell的样式资源：Key为dgCellStyle，使数据在单元格中居中显示：

 <Style x:Key="dgCellStyle" TargetType="{x:Type DataGridCell}">
            <Setter Property="Template">
                <Setter.Value>
                    <ControlTemplate TargetType="{x:Type DataGridCell}">
                        <Grid Background="{TemplateBinding Background}">
                            <ContentPresenter HorizontalAlignment="Center" VerticalAlignment="Center"></ContentPresenter>
                        </Grid>
                    </ControlTemplate>
                </Setter.Value>
            </Setter>
        </Style>

主窗口的资源中定义TabControl控件中的TabItem的样式：

 <DataTemplate DataType="{x:Type local:Department}">
            <Grid>
                <DataGrid ItemsSource="{Binding Path=Employees}"   AutoGenerateColumns="False" GridLinesVisibility="All"    SelectionMode="Single" IsReadOnly="True" CanUserAddRows="False" CanUserDeleteRows="False">
                    <DataGrid.Columns>
                        <DataGridTextColumn Header="姓名" Binding="{Binding Path=EmployeeName}" CellStyle="{StaticResource ResourceKey=dgCellStyle}" />
                        <DataGridTextColumn Header="性别" Binding="{Binding Sex}" CellStyle="{StaticResource ResourceKey=dgCellStyle}" />
                        <DataGridTextColumn Header="年龄" Binding="{Binding Age}" CellStyle="{StaticResource ResourceKey=dgCellStyle}" />
                        <DataGridTextColumn Header="职位" Binding="{Binding Title}" CellStyle="{StaticResource ResourceKey=dgCellStyle}"/>
                    </DataGrid.Columns>
                </DataGrid>
            </Grid>
        </DataTemplate>
