wpf devexpress在未束缚模式中生成Tree

TreeListControl 可以在未束缚模式中没有数据源时操作，这个教程示范如何在没有数据源时创建tree

在XAML生成tree

创建ProjectObject类实现数据对象显示在TreeListControl:

public class ProjectObject {
    public string Name { get; set; }
    public string Executor { get; set; }
}

添加TreeListControl到窗口。调用TreeListControl Quick Action和添加两行

绑定行到Name和Executor字段：

切换到XAML视图。定义TreeListControl视图：

创建根和子节点。TreeListControl存储根和子节点在TreeListView.Nodes和TreeListNode.Nodes集合中：

在代码中生成tree

创建ProjectObject类实现数据对象显示在TreeListControl:

public class ProjectObject {
    public string Name { get; set; }
    public string Executor { get; set; }
}

添加TreeListControl到window控件

创建两行和绑定Name和Executor字段：
 

在代码中创建根和子节点：
 

using DevExpress.Xpf.Grid;

// ...
public partial class MainWindow : Window {
    public MainWindow() {
        InitializeComponent();
        BuildTree();
    }

    void BuildTree() {
        TreeListNode rootNode = CreateRootNode(new ProjectObject() { Name = "Project: Stanton", Executor = "Nicholas Llams" });
        TreeListNode childNode = CreateChildNode(rootNode, new ProjectObject() { Name = "Information Gathering", Executor = "Ankie Galva" });
        CreateChildNode(childNode, new ProjectObject() { Name = "Design", Executor = "Reardon Felton" });
    }

    TreeListNode CreateRootNode(object dataObject) {
        TreeListNode rootNode = new TreeListNode(dataObject);
        treeListView1.Nodes.Add(rootNode);
        return rootNode;
    }

    TreeListNode CreateChildNode(TreeListNode parentNode, object dataObject) {
        TreeListNode childNode = new TreeListNode(dataObject);
        parentNode.Nodes.Add(childNode);
        return childNode;
    }
}
