关于DataGridView自定义列的问题

Question

我用的是VS2005.我想在WinForm加载时，在DataGridView中增加一个自定义列"操作"，该列有二个按钮"修改","删除",点击按钮触发相应事件，请问下这个应该怎么做?

Answer 1

可以有两列，一列修改，一列删除先在DataGridView中添加两列这样的按钮列，
隐藏着，看你什么 时候需要操作就显示出来

Answer 2

我要在一个列里放二个 linkbutton 这个怎么来做

Answer 3

你是看网页的惯性思维吧,你做这样的2个按钮在winform里面的datagridview不太好实现,你完全可以加2列datagridviewbuttoncolumn嘛

Answer 4

分2列最简单了啊，如果要放一列里就要定制了using System;
using System.Collections.Generic;
using System.ComponentModel;
using System.Data;
using System.Drawing;
using System.Text;
using System.Windows.Forms;
using System.Windows.Forms.VisualStyles;namespace WindowsApplication112
{
    public partial class Form1 : Form

        public Form1()

            InitializeComponent();            DataGridView DGV = new DataGridView();
            DGV.Parent = this;
            DGV.Dock = DockStyle.Fill;

            DGV.ColumnHeadersVisible = false;            DGV.Columns.Add(new TwoButtonColumn());
            DGV.Columns.Add(new TwoButtonColumn());            DGV.Rows.Add(3);
        }        class TwoButtonColumn : DataGridViewColumn

            bool B2Down = false;            public TwoButtonCell()
            {
                this.ValueType = typeof(String);                B1.Text = "修改";

            {

                ButtonRenderer.DrawButton(graphics, new Rectangle(B2.Location, B2.Size),

                Size B2StringSize = TextRenderer.MeasureText(B2.Text, B2.Font);                graphics.DrawString(B1.Text, B1.Font, new SolidBrush(B1.ForeColor),
                     Point.Add(B1.Location, new Size((B1.Width - B1StringSize.Width) / 2,
                     (B1.Height - B1StringSize.Height) / 2)));
                graphics.DrawString(B2.Text, B2.Font, new SolidBrush(B2.ForeColor),
                     Point.Add(B2.Location, new Size((B2.Width - B2StringSize.Width) / 2,
                     (B2.Height - B2StringSize.Height) / 2)));
            }            protected override void OnMouseDown(DataGridViewCellMouseEventArgs e)
            {
                Rectangle Test = this.DataGridView.GetCellDisplayRectangle(e.ColumnIndex, e.RowIndex, true);                if (Test.Contains(this.DataGridView .PointToClient(  Control.MousePosition)))
                    if (e.Location.X < Test.Width / 2)
                        B1Down = true;
                    else
                        B2Down = true;                base.OnMouseDown(e);
            }            protected override void OnMouseUp(DataGridViewCellMouseEventArgs e)
            {
                B1Down = false;
                B2Down = false;                base.OnMouseDown(e);
            }            // 以上代码实现了双按钮列的显示和相应鼠标
              // 但是还要相应click+=...等事件...............................
        }
    }

楼主是用web的编程方式处理winform的问题。
winform下，直接把按扭放到工具条中，焦点在DataGridView的单元格中。
如果想修改、删除，根据Row.Index Column.Index 直接操作就行了。WebForm模式（浏览器中），对界面控件的控制比较弱，那种处理方式是不得已而为之。
