C# winform 动态添加控件之GroupBox和TextBox

转自：http://www.cnblogs.com/lj1020/articles/2568885.html

一、添加GroupBox控件

 

1.实例化并显示

 

1 //实例化GroupBox控件
2             GroupBox groubox = new GroupBox();
3             groubox.Name = "gbDemo";
4             groubox.Text = "实例";
5             //设置上和左位置
6             //groubox.Top = 50;
7             //groubox.Left = 50;
8             //通过坐标设置位置
9             groubox.Location = new Point(12, 12);
10             //将groubox添加到页面上
11             this.Controls.Add(groubox);

 

 

 

二、在GroupBox控件中添加TextBox控件

 

1.实例化并显示

//实例化TextBox控件
TextBox txt = new TextBox();
txt.Name = "txtDemo";
txt.Text = "txt实例";
//将TextBox在GroupBox容器中显示
//txt.Parent = groubox;
//将TextBox在GroupBox容器中显示
groubox.Controls.Add(txt);

 

2.置于顶层和置于底层

1  //置于顶层
2             txt.BringToFront();
3             //置于底层
4             txt.SendToBack();

3.添加事件

1 //添加Click单击事件
2             txt.Click += new EventHandler(btn_Click);
3
4         }
5
6         //定义Click单击事件
7         private void btn_Click(object sender, EventArgs e)
8         {
9             MessageBox.Show("事件添加成功");
10         }

三、添加多个

1.动态添加多个

1 //添加控件
2         public void AddGroupBox()
3         {
4             string name = "gbox";
5             for (int i = 0; i < 3; i++)
6             {
7                 GroupBox gbox = new GroupBox();
8                 gbox.Name = name + i;
9                 gbox.Text=name+i;
10                 gbox.Width = 300;
11                 gbox.Height = 100;
12                 gbox.Location = new Point(32, 20 + i * 150);
13                 this.Controls.Add(gbox);
14                 //调用添加文本控件的方法
15                 AddTxt(gbox);
16             }
17         }
18         //添加文本控件
19         public void AddTxt(GroupBox gb)
20         {
21             string name = "txt";
22             for (int i = 0; i < 3; i++)
23             {
24                 TextBox txt = new TextBox();
25                 txt.Name =gb.Name+ name + i;
26                 txt.Text =gb.Name+"|"+ name + i;
27                 txt.Location = new Point(12, 15 + i * 30);
28                 gb.Controls.Add(txt);
29             }
30         }

20         {
