先来看看效果吧

升级报告说明

这次升级的功能主有
1.对鼠标跟随效果进行的优化
2.增加了行号的功能方便查找数据
3.增加一个菜单功能，目前里面有的功能主要是冻结和恢复首行和首列功能。还有导出Excel和全选功能。

实现说明

首先我们要准备两张图片，用来做什么呢，自然是用来做菜单使用的。我是临时整理了两张看着不怎么好看，不过功能不影响大家下载源代码后要吧自行修改的漂亮一些。

然后我们第一步要做的是怎么样把这个图片添加到DataGridView里面去。在添加这个控件之前呢我们要做两件事情，第一就是New一个左键菜单，绑定到这个菜单Button，
第二步是给这个button注册一个单击事件看下面的代码。

[C#] 纯文本查看 复制代码

#region 注册菜单项
            //在这里添加菜单项
            cmsleft.Items.Add(createItem("clumnsFist", "冻结首列", new EventHandler(clumnsFist_Click)));
            cmsleft.Items.Add(createItem("rowsFist", "冻结首行", new EventHandler(rowsFistFist_Click)));
            cmsleft.Items.Add(createItem("officeExeceout", "导出到Excel", new EventHandler(officeExeceout_Click)));
            cmsleft.Items.Add(createItem("fullSelect", "全选", new EventHandler(fullSelect_Click)));
            #endregion

            #region 绑定菜单

            Button objpb = new Button();
            objpb.BackgroundImage = bxyztSkin.Properties.Resources.caidan;
            objpb.Location = new Point(objpb.Location.X + 9, objpb.Location.Y + 4);
            objpb.Width = 17;
            objpb.Text = "";
            //绑定一个右键菜单
            objpb.ContextMenuStrip = cmsleft;
            objpb.Cursor = System.Windows.Forms.Cursors.Hand;
            objpb.Height = 17;
            objpb.BackgroundImageLayout = ImageLayout.Stretch;
            objpb.FlatStyle = FlatStyle.Popup;
            //在添加前先注册一个事件
            objpb.Click += new EventHandler(objpb_Click);
            this.Controls.Add(objpb);

            #endregion

这样的话我们在运行这个控件时就可以看到菜单效果了，下面我们来分别对事件进行一下处理吧
1.Button单击事件

[C#] 纯文本查看 复制代码

//Button单击事件
        void objpb_Click(object sender, EventArgs e)
        {
            Button objbootn = (Button)sender;
            //显示菜单的位置
            objbootn.ContextMenuStrip.Show(Control.MousePosition.X, Control.MousePosition.Y);
        }

2.全选事件

//全选
        void fullSelect_Click(object sender, EventArgs e)
        {
            this.SelectAll();
        }[/code]
3.导出到Excel事件
[code=csharp]//导出到Excel
        void officeExeceout_Click(object sender, EventArgs e)
        {
            if (this.Rows.Count > 0)
            {
                OfficeManagerMentServices.DataGridViewToExcel(this);
            }
        }

OfficeManagerMentServices类如下

            SaveFileDialog dlg = new SaveFileDialog();
            dlg.Filter = "Execl files (*.xls)|*.xls";

            if (dlg.ShowDialog() == DialogResult.OK)

                Stream myStream;
                myStream = dlg.OpenFile();
                StreamWriter sw = new StreamWriter(myStream, System.Text.Encoding.GetEncoding(-0));
                string columnTitle = "";
                try
                {
                    //写入列标题   
                    for (int i = 0; i < dgv.ColumnCount; i++)
                    {
                        if (i > 0)
                        {
                            columnTitle += "\t";
                        }
                        columnTitle += dgv.Columns.HeaderText;
                    }
                    sw.WriteLine(columnTitle);

                    //写入列内容   
                    for (int j = 0; j < dgv.Rows.Count; j++)
                    {
                        string columnValue = "";
                        for (int k = 0; k < dgv.Columns.Count; k++)
                        {
                            if (k > 0)
                            {
                                columnValue += "\t";
                            }
                            if (dgv.Rows[j].Cells[k].Value == null)
                                columnValue += "";
                            else
                                columnValue += dgv.Rows[j].Cells[k].Value.ToString().Trim();
                        }
                        sw.WriteLine(columnValue);
                    }
                    sw.Close();
                    myStream.Close();
                }
                catch (Exception e)
                {
                    MessageBox.Show(e.ToString());
                }
                finally
                {
                    sw.Close();
                    myStream.Close();
                }
            }
        }
    }
}

4.冻结/恢复首列

[C#] 纯文本查看 复制代码

//冻结/恢复首列
        void clumnsFist_Click(object sender, EventArgs e)
        {
            if (this.Columns.Count >= 1)
            {
                for (int i = 0; i < this.Columns.Count; i++)
                {
                    if (this.Columns.Visible == true)
                    {
                        if (this.Columns.Frozen)
                        {
                            this.Columns.Frozen = false;
                            ((ToolStripMenuItem)sender).Text = "冻结首列";
                            return;
                        }
                        else
                        {
                            this.Columns.Frozen = true;
                            ((ToolStripMenuItem)sender).Text = "恢复首列";
                            return;
                        }
                    }
                }
            }
        }

5.冻结/恢复首行

[C#] 纯文本查看 复制代码

//冻结/恢复首行
        void rowsFistFist_Click(object sender, EventArgs e)
        {
            if (this.Rows.Count >= 1)
            {
                if (this.Rows[0].Frozen)
                {
                    this.Rows[0].Frozen = false;
                    ((ToolStripMenuItem)sender).Text = "冻结首行";
                }
                else
                {
                    this.Rows[0].Frozen = true;
                    ((ToolStripMenuItem)sender).Text = "解冻首行";
                }
            }
        }

还有一个提供创建新的菜单项的方法

/// <summary>
        /// 创建新的菜单项
        /// </summary>
        /// <param name="name">菜单名</param>
        /// <param name="Text">显示文字</param>
        /// <param name="objEh">绑定事件</param>
        /// <returns>返一个ToolStripMenuItem对象</returns>
        private ToolStripMenuItem createItem(string name, string Text, EventHandler objEh)
        {
            System.Windows.Forms.ToolStripMenuItem lolumns = new System.Windows.Forms.ToolStripMenuItem();
            lolumns.ForeColor = System.Drawing.Color.Black;
            lolumns.Name = name;
            lolumns.Size = new System.Drawing.Size(152, 24);
            lolumns.Text = Text;
            lolumns.Click += objEh;
            return lolumns;
        }
