C#--DataGridView（干货版）_c# datagridview

一、添加行列并获取信息

代码如下：

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

namespace DataGridView
{
    public partial class Form1 : Form
    {
        int count = 0;
        public Form1()
        {
            InitializeComponent();
        }

        private void Form1_Load(object sender, EventArgs e)
        {
            //根据Header和所有单元格的内容自动调整行的高度
            dataGridView1.AutoSizeRowsMode = DataGridViewAutoSizeRowsMode.AllCells;  
            //添加三列
            for (int i = 0; i < 3; i++)
            {
                dataGridView1.Columns.Add(new DataGridViewTextBoxColumn());
                dataGridView1.Columns[i].AutoSizeMode = DataGridViewAutoSizeColumnMode.AllCells;  //设置所有列自适应宽度
            }
            //三列的标题
            dataGridView1.Columns[0].HeaderText = "序号";
            dataGridView1.Columns[1].HeaderText = "日期";
            dataGridView1.Columns[2].HeaderText = "说明";
            //设置对齐方式和字体
            dataGridView1.RowsDefaultCellStyle.Alignment = DataGridViewContentAlignment.MiddleCenter;
            dataGridView1.Font = new Font("宋体", 11);
        }
        //添加行
        private void button1_Click(object sender, EventArgs e)
        {
            int index = this.dataGridView1.Rows.Add();
            this.dataGridView1.Rows[index].Cells[0].Value = count++;
            this.dataGridView1.Rows[index].Cells[1].Value = "2";
            this.dataGridView1.Rows[index].Cells[2].Value = "监听";
        }
        //获取信息
        private void button2_Click(object sender, EventArgs e)
        {
            //获取当前活动单元格内容
            Console.WriteLine("当前活动单元格内容：" + dataGridView1.CurrentCell.Value);  
             //取得当前单元格的列Index
            Console.WriteLine("当前单元格的列Index：" + dataGridView1.CurrentCell.ColumnIndex); 
            //取得当前单元格的行Index
            Console.WriteLine("取得当前单元格的行Index：" + dataGridView1.CurrentCell.RowIndex);   
            // 设定 (1, 1) 为当前单元格 
            dataGridView1.CurrentCell = dataGridView1[1, 1];   
        }
    }
}
