少有人走的路正常的添加根结点的效果如下：
但是勇哥使用时是这样的
其原因是没有指定显示内容的属性。
TreeViewAdv控件的显示内容包括： 选择框、文件夹图标、textbox控件
你得先指定这些要显示的对象的属性
演示代码：
using Aga.Controls.Tree;
using System;
using System.Collections.Generic;
using System.ComponentModel;
using System.Data;
using System.Drawing;
using System.Linq;
using System.Text;
using System.Threading.Tasks;
using System.Windows.Forms;
namespace WindowsFormsApplication2
{
public partial class Form1 : Form
{
private Aga.Controls.Tree.NodeControls.NodeCheckBox _nodeCheckBox;
private Aga.Controls.Tree.NodeControls.NodeStateIcon _nodeStateIcon;
private Aga.Controls.Tree.NodeControls.NodeTextBox _nodeTextBox;
private TreeModel _model;
public Form1()
{
InitializeComponent();
this._nodeCheckBox = new Aga.Controls.Tree.NodeControls.NodeCheckBox();
this._nodeStateIcon = new Aga.Controls.Tree.NodeControls.NodeStateIcon();
this._nodeTextBox = new Aga.Controls.Tree.NodeControls.NodeTextBox();
this._nodeTextBox.DataPropertyName = "Text";
this._nodeTextBox.EditEnabled = true;
this._tree.NodeControls.Add(this._nodeCheckBox);
this._tree.NodeControls.Add(this._nodeStateIcon);
this._tree.NodeControls.Add(this._nodeTextBox);
_model = new TreeModel();
_tree.Model = _model;
ChangeButtons();
}
private void button1_Click(object sender, EventArgs e)
{
Node node = new Node("root222222" + _model.Nodes.Count.ToString());
_model.Nodes.Add(node);
_tree.SelectedNode = _tree.FindNode(_model.GetPath(node));
}
private void Form1_Load(object sender, EventArgs e)
{
}
private void ChangeButtons()
{
//_addChild.Enabled = _deleteNode.Enabled = (_tree.SelectedNode != null);
}
}
}现在有了。
