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：
<dxg:TreeListControl Name="treeListControl1"><dxg:TreeListControl.Columns><dxg:TreeListColumn FieldName="Name"/><dxg:TreeListColumn FieldName="Executor"/></dxg:TreeListControl.Columns>
</dxg:TreeListControl>切换到XAML视图。定义TreeListControl视图：
<dxg:TreeListControl Name="treeListControl1"><dxg:TreeListControl.Columns><dxg:TreeListColumn FieldName="Name"/><dxg:TreeListColumn FieldName="Executor"/></dxg:TreeListControl.Columns><dxg:TreeListControl.View><dxg:TreeListView Name="treeListView1"/></dxg:TreeListControl.View>
</dxg:TreeListControl>创建根和子节点。TreeListControl存储根和子节点在TreeListView.Nodes和TreeListNode.Nodes集合中：
<dxg:TreeListControl.View><dxg:TreeListView Name="treeListView1"><dxg:TreeListView.Nodes><dxg:TreeListNode><dxg:TreeListNode.Content><local:ProjectObject Name="Project: Betaron" Executor="Destiny Tabisola" /></dxg:TreeListNode.Content><dxg:TreeListNode.Nodes><dxg:TreeListNode><dxg:TreeListNode.Content><local:ProjectObject Name="Development" Executor="Kairra Hogg" /></dxg:TreeListNode.Content><dxg:TreeListNode.Nodes><dxg:TreeListNode><dxg:TreeListNode.Content><local:ProjectObject Name="Coding" Executor="Sabato Durley" /></dxg:TreeListNode.Content></dxg:TreeListNode></dxg:TreeListNode.Nodes></dxg:TreeListNode></dxg:TreeListNode.Nodes></dxg:TreeListNode></dxg:TreeListView.Nodes></dxg:TreeListView>
</dxg:TreeListControl.View>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：
<dxg:TreeListControl Name="treeListControl1"><dxg:TreeListControl.Columns><dxg:TreeListColumn FieldName="Name"/><dxg:TreeListColumn FieldName="Executor"/></dxg:TreeListControl.Columns><dxg:TreeListControl.View><dxg:TreeListView Name="treeListView1"/></dxg:TreeListControl.View>
</dxg:TreeListControl>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;}
}
