TextBox和AdvTree的链接以及对AdvTree中数据进行增删改查操作代码

1. TextBox和AdvTree的链接

可以通过AdvTree的AfterNodeSelect事件来实现TextBox和AdvTree的链接，代码如下：

private void advTree1_AfterNodeSelect(object sender, DevComponents.AdvTree.AdvTreeNodeEventArgs e)
{
    textBox1.Text = e.Node.Cells[0].Text;
}

2. 对AdvTree中数据进行增删改查操作代码

以下是一些常用的对AdvTree中数据进行增删改查操作的代码示例：

（1）添加节点

private void addButton_Click(object sender, EventArgs e)
{
    AdvTreeNode node = new AdvTreeNode("New Node");
    advTree1.Nodes.Add(node);
}

（2）删除节点

private void deleteButton_Click(object sender, EventArgs e)
{
    if (advTree1.SelectedNode != null)
    {
        advTree1.Nodes.Remove(advTree1.SelectedNode);
    }
}

（3）修改节点

private void updateButton_Click(object sender, EventArgs e)
{
    if (advTree1.SelectedNode != null)
    {
        advTree1.SelectedNode.Cells[0].Text = "New Text";
    }
}

（4）查找节点

private void searchButton_Click(object sender, EventArgs e)
{
    string searchText = textBox1.Text;
    AdvTreeNode node = advTree1.FindNodeByText(searchText);
    if (node != null)
    {
        advTree1.SelectedNode = node;
    }
}
