wpfdevexpress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：

<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; } }
