添加数据模型Employee和Staff类到MainWindow.xaml.cs 文件
namespace DxTreeListGettingStarted {public partial class MainWindow : Window { ... }public class Employee {public int ID { get; set; }public int ParentID { get; set; }public string Name { get; set; }public string Position { get; set; }public string Department { get; set; }}public static class Staff {public static ListEmployee GetStaff() {ListEmployee staff new ListEmployee();staff.Add(new Employee() { ID 0, Name Gregory S. Price, Department , Position President });staff.Add(new Employee() { ID 1, ParentID 0, Name Irma R.

}
设置window数据上下文到视图模型
Window... Window.DataContextlocal:MainWindowViewModel//Window.DataContext
添加TreeListControl到视图
拖动TreeListControl组件从工具箱到form里面
选择TreeListControl点击Quick Actions
点击重新计算按钮到ItemsSource属性调用上下文菜单。选择创建数据绑定 选择Employees在对话框点击OK 设置AutoGenerateColumns添加AddNew 切换到XAML视图定义TreeListControl 视图
dxg:TreeListControl AutoGenerateColumnsAddNew ItemsSource{Binding Employees}dxg:TreeListControl.Viewdxg:TreeListView //dxg:TreeListControl.View
/dxg:TreeListControl
返回设计器视图选择TreeListView调用Quick Actions
启动AutoWidth和AutoExpandAllNodes选项。指定服务行TreeListView.KeyFieldName 和 TreeListView.ParentFieldName生成tree dxg:TreeListControl ItemsSource{Binding Employees}AutoGenerateColumnsAddNew dxg:TreeListControl.Viewdxg:TreeListView KeyFieldNameID ParentFieldNameParentIDAutoWidthTrue AutoExpandAllNodesTrue //dxg:TreeListControl.View
