C#:从树视图中搜索 [英] C#:Search from treeview

问题描述

我从 XML 文件加载了一个树视图数据.我想在用户在文本框中键入内容时执行搜索.这是正确的做法吗??我只想过滤数据.请给我举个例子.

I got a treeview data loaded from a XML file. I want to perform a search when the user types something in the textbox. Is that the right way of doing it?? I just want to filter the data. Please show me some example.

以下代码无效.

 textBox1.Enter += new EventHandler(txtSearch_TextChanged);

 private void txtSearch_TextChanged(object sender, EventArgs e)
        {

            foreach (TreeNode node in this.treeView1.Nodes)
            {

                if (node.Text.ToUpper().Contains(this.textBox1.Text.ToUpper()))
                {

                    treeView1.SelectedNode = node;

                    break;

                }
  }

推荐答案

您需要注册文本更改事件:http://msdn.microsoft.com/en-us/library/system.web.ui.webcontrols.textbox.textchanged.aspx

you need to register to the text changed event: http://msdn.microsoft.com/en-us/library/system.web.ui.webcontrols.textbox.textchanged.aspx

以及查找特定节点使用:

and for finding the specific node use:

treeView1.Nodes.Find()
