添加一个数据模型

AccordionControl可以被束缚到任何实现IEnumerable接口的对象或者它的派生类（例如IList,ICollection）

如下代码例子示范了一个简单的数据模型使用：

using System.Collections.Generic;

namespace DxAccordionGettingStarted {
    public class Employee {
        public int ID { get; set; }
        public string Name { get; set; }
        public string Position { get; set; }
        public string Department { get; set; }
        public override string ToString() {
            return Name;
        }
    }

    public static class Staff {
        public static List<Employee> GetStaff() {
            List<Employee> employees = new List<Employee>();
            employees.Add(new Employee() { ID = 1, Name = "Gregory S. Price", Department = "Management", Position = "President" });
            employees.Add(new Employee() { ID = 2, Name = "Irma R. Marshall", Department = "Marketing", Position = "Vice President" });
            employees.Add(new Employee() { ID = 3, Name = "John C. Powell", Department = "Operations", Position = "Vice President" });
            employees.Add(new Employee() { ID = 4, Name = "Christian P. Laclair", Department = "Production", Position = "Vice President" });
            employees.Add(new Employee() { ID = 5, Name = "Karen J. Kelly", Department = "Finance", Position = "Vice President" });

            employees.Add(new Employee() { ID = 6, Name = "Brian C. Cowling", Department = "Marketing", Position = "Manager" });
            employees.Add(new Employee() { ID = 7, Name = "Thomas C. Dawson", Department = "Marketing", Position = "Manager" });
            employees.Add(new Employee() { ID = 8, Name = "Angel M. Wilson", Department = "Marketing", Position = "Manager" });
            employees.Add(new Employee() { ID = 9, Name = "Bryan R. Henderson", Department = "Marketing", Position = "Manager" });

            employees.Add(new Employee() { ID = 10, Name = "Harold S. Brandes", Department = "Operations", Position = "Manager" });
            employees.Add(new Employee() { ID = 11, Name = "Michael S. Blevins", Department = "Operations", Position = "Manager" });
            employees.Add(new Employee() { ID = 12, Name = "Jan K. Sisk", Department = "Operations", Position = "Manager" });
            employees.Add(new Employee() { ID = 13, Name = "Sidney L. Holder", Department = "Operations", Position = "Manager" });

            employees.Add(new Employee() { ID = 14, Name = "James L. Kelsey", Department = "Production", Position = "Manager" });
            employees.Add(new Employee() { ID = 15, Name = "Howard M. Carpenter", Department = "Production", Position = "Manager" });
            employees.Add(new Employee() { ID = 16, Name = "Jennifer T. Tapia", Department = "Production", Position = "Manager" });

            employees.Add(new Employee() { ID = 17, Name = "Judith P. Underhill", Department = "Finance", Position = "Manager" });
            employees.Add(new Employee() { ID = 18, Name = "Russell E. Belton", Department = "Finance", Position = "Manager" });
            return employees;
        }
    }
}

添加视图模型

创建视图模型从数据模型中调用数据：

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

namespace DxAccordionGettingStarted {
    public class MainWindowViewModel {
        public MainWindowViewModel() {
            var employeeDepartments = Staff.GetStaff()
                .GroupBy(x => x.Department)
                .Select(x => new EmployeeDepartment(x.Key, x.ToArray()));
            EmployeeDepartments = new ObservableCollection<EmployeeDepartment>(employeeDepartments.ToArray());
        }
        public ObservableCollection<EmployeeDepartment> EmployeeDepartments { get; set; }
    }

    public class EmployeeDepartment {
        public string Name { get; set; }
        public ObservableCollection<Employee> Employees { get; set; }

        public EmployeeDepartment(string name, IEnumerable<Employee> employees) {
            Name = name;
            Employees = new ObservableCollection<Employee>(employees);
        }
        public override string ToString() {
            return Name;
        }
    }
}

生成解决方案。调用MainWindow Quick Actions和定义窗口数据上下文作为如下图片显示：

添加AccordionControl到视图

拖动AccordionControl从DX.23.1:Navigation & Layout工具箱页面，拖动到MainWindow：

右键点击控件选择Layout | Reset All去允许AccordionControl填充整个窗口：

绑定AccordionControl到数据

调用AccordinControl Quick Action和定义ItemsSource字段：

定义ChildrenPath字段指定路径到属性包含一个accordion item子对象：

代码例子如下示范了生成的代码：

<Window  
   xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation" 
   xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml" 
   xmlns:dxa="http://schemas.devexpress.com/winfx/2008/xaml/accordion" 
   xmlns:local="clr-namespace:DxAccordionGettingStarted" 
   x:Class="DxAccordionGettingStarted.MainWindow" 
   Title="MainWindow" Height="350" Width="525">
    <Window.DataContext>
        <local:MainWindowViewModel/>
    </Window.DataContext>
    <Grid>
        <dxa:AccordionControl ItemsSource="{Binding EmployeeDepartments}" ChildrenPath="Employees"/>
    </Grid>
</Window>
