C# winform 動態添加控件之GroupBox和TextBox

一、添加GroupBox控件

 

1.實例化並顯示

 

//實例化GroupBox控件
            GroupBox groubox = new GroupBox();
            groubox.Name = "gbDemo";
            groubox.Text = "實例";
            //設置上和左位置
            //groubox.Top = 50;
            //groubox.Left = 50;
            //通過坐標設置位置
            groubox.Location = new Point(12, 12);
            //將groubox添加到頁面上
            this.Controls.Add(groubox);

 

 

 

二、在GroupBox控件中添加TextBox控件

 

1.實例化並顯示

//實例化TextBox控件
            TextBox txt = new TextBox();
            txt.Name = "txtDemo";
            txt.Text = "txt實例";
            //將TextBox在GroupBox容器中顯示
            //txt.Parent = groubox;
            //將TextBox在GroupBox容器中顯示
            groubox.Controls.Add(txt);

 

2.置於頂層和置於底層

 //置於頂層
            txt.BringToFront();
            //置於底層
            txt.SendToBack();

3.添加事件

//添加Click單擊事件
            txt.Click += new EventHandler(btn_Click);

        }

        //定義Click單擊事件
        private void btn_Click(object sender, EventArgs e)
        {
            MessageBox.Show("事件添加成功");
        }

三、添加多個

1.動態添加多個

//添加控件
        public void AddGroupBox()
        {
            string name = "gbox";
            for (int i = 0; i < 3; i++)
            {
                GroupBox gbox = new GroupBox();
                gbox.Name = name + i;
                gbox.Text=name+i;
                gbox.Width = 300;
                gbox.Height = 100;
                gbox.Location = new Point(32, 20 + i * 150);
                this.Controls.Add(gbox);
                //調用添加文本控件的方法
                AddTxt(gbox);
            }
        }
        //添加文本控件
        public void AddTxt(GroupBox gb)
        {
            string name = "txt";
            for (int i = 0; i < 3; i++)
            {
                TextBox txt = new TextBox();
                txt.Name =gb.Name+ name + i;
                txt.Text =gb.Name+"|"+ name + i;
                txt.Location = new Point(12, 15 + i * 30);
                gb.Controls.Add(txt);
            }
        }

 

實例：

using System;
using System.Collections.Generic;
using System.ComponentModel;
using System.Data;
using System.Drawing;
using System.Linq;
using System.Text;
using System.Windows.Forms;

namespace Select_ListBox
{
    public partial class Form2 : Form
    {TextBox txt = new TextBox();
        public Form2()
        {
            InitializeComponent();
        }

        private void Form2_Load(object sender, EventArgs e)
        {
            AddGroupBox();
            ////實例化GroupBox控件
            //GroupBox groubox = new GroupBox();
            //groubox.Name = "gbDemo";
            //groubox.Text = "實例";
            ////設置上和左位置
            ////groubox.Top = 50;
            ////groubox.Left = 50;
            ////通過坐標設置位置
            //groubox.Location = new Point(12, 12);
            ////將groubox添加到頁面上
            //this.Controls.Add(groubox);

            ////實例化TextBox控件
            //TextBox txt = new TextBox();
            //txt.Name = "txtDemo";
            //txt.Text = "txt實例";
            ////將TextBox在GroupBox容器中顯示
            ////txt.Parent = groubox;
            ////將TextBox在GroupBox容器中顯示
            //groubox.Controls.Add(txt);
            
            ////置於頂層
            //txt.BringToFront();
            ////置於底層
            //txt.SendToBack();
            ////添加Click單擊事件
            //txt.Click += new EventHandler(btn_Click);

        }

        ////定義Click單擊事件
        //private void btn_Click(object sender, EventArgs e)
        //{
        //    MessageBox.Show("ss");
        //}

        //添加控件
        public void AddGroupBox()
        {
            string name = "gbox";
            for (int i = 0; i < 3; i++)
            {
                GroupBox gbox = new GroupBox();
                gbox.Name = name + i;
                gbox.Text=name+i;
                gbox.Width = 300;
                gbox.Height = 100;
                gbox.Location = new Point(32, 20 + i * 150);
                this.Controls.Add(gbox);
                //調用添加文本控件的方法
                AddTxt(gbox);
            }
        }
        //添加文本控件
        public void AddTxt(GroupBox gb)
        {
            string name = "txt";
            for (int i = 0; i < 3; i++)
            {
                TextBox txt = new TextBox();
                txt.Name =gb.Name+ name + i;
                txt.Text =gb.Name+"|"+ name + i;
                txt.Location = new Point(12, 15 + i * 30);
                gb.Controls.Add(txt);
            }
        }
    }
}
