C#控件使用

本篇存放在学习过程中遇到的各种C#控件使用方法

TreeView控件使用：

private void TreeViewForm_Load(object sender, EventArgs e)
     {
         treeView.LabelEdit = true;  //可编辑状态
 
         TreeNode node = new TreeNode(); //新建一个根节点
         node.Text = "根节点1";
         treeView.Nodes.Add(node);     //添加根节点
 
         TreeNode node1 = new TreeNode();
         node1.Text = "节点1";
 
         TreeNode node11 = new TreeNode();
         node11.Text = "节点11";
 
         TreeNode node2 = new TreeNode();
         node2.Text = "节点2";
 
         node1.Nodes.Add(node11);   //在node1下添加一个节点node11
 
         node.Nodes.Add(node1);      //在根节点下添加节点node1、node2
         node.Nodes.Add(node2);
 
         TreeNode t = new TreeNode("根节点2");
         node.Text = "根节点1";
         treeView.Nodes.Add(t);     //添加根节点
 
         TreeNode t1 = new TreeNode();
         t1.Text = "节点1";
 
         TreeNode t11 = new TreeNode();
         t11.Text = "节点11";
 
         TreeNode t2 = new TreeNode();
         t2.Text = "节点2";
 
         t1.Nodes.Add(t11);   //在t1下添加一个节点t11
 
         t.Nodes.Add(t1);      //在根节点下添加节点t1、t2
         t.Nodes.Add(t2);
 
     }
 
     private void treeView_AfterSelect(object sender, TreeViewEventArgs e)
     {
         label_SelectResult.Text = treeView.SelectedNode.Text;   //获取选中节点Text
     }
 
     private void button_Edit_Click(object sender, EventArgs e)
     {
         treeView.SelectedNode.BeginEdit();     //编辑选中的节点
     }
 
     private void button_Delete_Click(object sender, EventArgs e)
     {
         treeView.Nodes.Remove(treeView.SelectedNode);   //删除选中节点
     }
