要在Winform中實現TreeListView的節點操作,你需要使用一個第三方庫,例如BrightIdeasSoftware的ObjectListView。這是一個功能強大的列表視圖控件,支持多列、排序、篩選等功能,而且還可以像TreeView一樣顯示層次結構。
首先,你需要下載并安裝ObjectListView。你可以從GitHub上下載:https://github.com/bright-tools/ObjectListView
接下來,按照以下步驟實現TreeListView的節點操作:
添加ObjectListView到你的項目中:
在你的Form上添加一個TreeListView控件:
創建一個數據模型類,用于表示TreeListView的節點:
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);
}
現在你已經成功地在Winform中實現了TreeListView的節點操作。你可以根據需要進一步自定義TreeListView的行為和外觀。更多關于ObjectListView的信息和示例,請參考官方文檔:http://objectlistview.sourceforge.net/cs/index.html
