要在Winform中实现TreeListView的节点操作,你需要使用一个第三方库,例如BrightIdeasSoftware的ObjectListView。这是一个功能强大的列表视图控件,支持多列、排序、筛选等功能,而且还可以像TreeView一样显示层次结构。
首先,你需要下载并安装ObjectListView。你可以从GitHub上下载:https://github.com/bright-tools/ObjectListView
接下来,按照以下步骤实现TreeListView的节点操作:
添加ObjectListView到你的项目中:
在你的Form上添加一个TreeListView控件:
创建一个数据模型类,用于表示TreeListView的节点:
public class Node
{
public string Name { get; set; }
public List<Node> Children { get; set; }
}
using BrightIdeasSoftware;
public partial class Form1 : Form
{
private TreeListView treeListView;
public Form1()
{
InitializeComponent();
treeListView = new TreeListView();
treeListView.Dock = DockStyle.Fill;
treeListView.CanExpandGetter = x => (x as Node).Children != null && (x as Node).Children.Count > 0;
treeListView.ChildrenGetter = x => (x as Node).Children;
this.Controls.Add(treeListView);
LoadData();
}
private void LoadData()
{
var rootNode = new Node
{
Name = "Root",
Children = new List<Node>
{
new Node { Name = "Child 1" },
new Node { Name = "Child 2" },
new Node { Name = "Child 3" }
}
};
treeListView.Roots = new List<Node> { rootNode };
}
}
private void btnAddNode_Click(object sender, EventArgs e)
{
var selectedNode = treeListView.SelectedObject as Node;
if (selectedNode == null) return;
var newNode = new Node { Name = "New Node" };
if (selectedNode.Children == null)
{
selectedNode.Children = new List<Node>();
}
selectedNode.Children.Add(newNode);
treeListView.RefreshObject(selectedNode);
}
private void btnDeleteNode_Click(object sender, EventArgs e)
{
var selectedNode = treeListView.SelectedObject as Node;
if (selectedNode == null) return;
var parentNode = treeListView.GetParent(selectedNode) as Node;
if (parentNode != null)
{
parentNode.Children.Remove(selectedNode);
treeListView.RefreshObject(parentNode);
}
else
{
var roots = treeListView.Roots as List<Node>;
roots.Remove(selectedNode);
treeListView.Roots = roots;
}
}
private void btnEditNode_Click(object sender, EventArgs e)
{
var selectedNode = treeListView.SelectedObject as Node;
if (selectedNode == null) return;
selectedNode.Name = "Edited Node";
treeListView.RefreshObject(selectedNode);
}
现在你已经成功地在Winform中实现了TreeListView的节点操作。你可以根据需要进一步自定义TreeListView的行为和外观。更多关于ObjectListView的信息和示例,请参考官方文档:http://objectlistview.sourceforge.net/cs/index.html
