datagridview在winform的框架裏面就和html裏面的table同樣。
但不一樣的是,原生的datagridview裏面並無操做列這個概念,默認的列類型 有下拉框、文本、按鈕、圖片、連接這幾類,若是須要其餘的樣式還須要從新寫。html
其實大部分需求都是如圖的效果,固然你使用了別的組件【不是官方自帶】,可能實現如圖的效果很簡單git
下面講講如圖==》操做列 有多個按鈕的不一樣實現方式後端
1.1 方式一
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 chao.net{ public partial class FormTest2 : Form { public FormTest2() { InitializeComponent(); } private void toolStripLabel1_Click(object sender, EventArgs e) { } private void FormTest2_Load(object sender, EventArgs e) { this.dataGridView1.AutoGenerateColumns = false;; this.dataGridView1.CellMouseClick += dataGridView1_CellMouseClick; this.dataGridView1.CellPainting += dataGridView1_CellPainting; this.dataGridView1.Rows.Add(); } /// <summary> /// 單元格重繪 /// </summary> /// <param name="sender"></param> /// <param name="e"></param> private void dataGridView1_CellPainting(object sender, DataGridViewCellPaintingEventArgs e) { if (e.ColumnIndex >= 0 && e.RowIndex >= 0) { if (this.dataGridView1.Columns[e.ColumnIndex].HeaderText == "操做") { StringFormat sf = StringFormat.GenericDefault.Clone() as StringFormat;//設置重繪入單元格的字體樣式 sf.FormatFlags = StringFormatFlags.DisplayFormatControl; sf.Alignment = StringAlignment.Center; sf.LineAlignment = StringAlignment.Center; sf.Trimming = StringTrimming.EllipsisCharacter; //e.PaintContent e.PaintBackground(e.CellBounds, false);//重繪邊框 //設置要寫入字體的大小 System.Drawing.Font myFont = new System.Drawing.Font("微軟雅黑", 9F, System.Drawing.FontStyle.Underline, System.Drawing.GraphicsUnit.Point, ((byte)(134))); //myFon SizeF sizeDel = e.Graphics.MeasureString("刪除", myFont); SizeF sizeMod = e.Graphics.MeasureString("修改", myFont); SizeF sizeLook = e.Graphics.MeasureString("查看", myFont); float fDel = sizeDel.Width / (sizeDel.Width + sizeMod.Width + sizeLook.Width); // float fMod = sizeMod.Width / (sizeDel.Width + sizeMod.Width + sizeLook.Width); float fLook = sizeLook.Width / (sizeDel.Width + sizeMod.Width + sizeLook.Width); //設置每一個「按鈕的邊界」 RectangleF rectDel = new RectangleF(e.CellBounds.Left, e.CellBounds.Top, e.CellBounds.Width * fDel, e.CellBounds.Height); RectangleF rectMod = new RectangleF(rectDel.Right, e.CellBounds.Top, e.CellBounds.Width * fMod, e.CellBounds.Height); RectangleF rectLook = new RectangleF(rectMod.Right, e.CellBounds.Top, e.CellBounds.Width * fLook, e.CellBounds.Height); e.Graphics.DrawString("刪除", myFont, Brushes.Black, rectDel, sf); //繪製「按鈕」 e.Graphics.DrawString("修改", myFont, Brushes.Black, rectMod, sf); e.Graphics.DrawString("查看", myFont, Brushes.Black, rectLook, sf); e.Handled = true; } } } /// <summary> /// 鼠標點擊事件 /// </summary> /// <param name="sender"></param> /// <param name="e"></param> private void dataGridView1_CellMouseClick(object sender, DataGridViewCellMouseEventArgs e) { if (e.ColumnIndex >= 0 && e.RowIndex >= 0) { Point curPosition = e.Location;//當前鼠標在當前單元格中的座標 if (this.dataGridView1.Columns[e.ColumnIndex].HeaderText == "操做") { //this.dataGridView1.Columns[e.ColumnIndex].Add Graphics g = this.dataGridView1.CreateGraphics(); System.Drawing.Font myFont = new System.Drawing.Font("宋體", 9F, System.Drawing.FontStyle.Underline, System.Drawing.GraphicsUnit.Point, ((byte)(134))); SizeF sizeDel = g.MeasureString("刪除", myFont); SizeF sizeMod = g.MeasureString("修改", myFont); SizeF sizeLook = g.MeasureString("查看", myFont); float fDel = sizeDel.Width / (sizeDel.Width + sizeMod.Width + sizeLook.Width); float fMod = sizeMod.Width / (sizeDel.Width + sizeMod.Width + sizeLook.Width); float fLook = sizeLook.Width / (sizeDel.Width + sizeMod.Width + sizeLook.Width); Rectangle rectTotal = new Rectangle(0, 0, this.dataGridView1.Columns[e.ColumnIndex].Width, this.dataGridView1.Rows[e.RowIndex].Height); RectangleF rectDel = new RectangleF(rectTotal.Left, rectTotal.Top, rectTotal.Width * fDel, rectTotal.Height); RectangleF rectMod = new RectangleF(rectDel.Right, rectTotal.Top, rectTotal.Width * fMod, rectTotal.Height); RectangleF rectLook = new RectangleF(rectMod.Right, rectTotal.Top, rectTotal.Width * fLook, rectTotal.Height); //判斷當前鼠標在哪一個「按鈕」範圍內 if (rectDel.Contains(curPosition))//刪除 MessageBox.Show("點擊刪除按鈕"); else if (rectMod.Contains(curPosition))//修改 MessageBox.Show("點擊修改按鈕"); else if (rectLook.Contains(curPosition))//查看 MessageBox.Show("點擊查看按鈕"); } } } private void dataGridView1_CellContentClick(object sender, DataGridViewCellEventArgs e) { } }}
主要方法是:dataGridView1_CellPainting 就是從新繪製單元格。代碼在FormTest2.cs裏面,進入連接在最下面。框架
效果:字體
1.2 方式二
使用右鍵菜單==》也可套用點擊行裏面的按鈕顯示菜單。【學會觸類旁通就行】this
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 chao.net{ public partial class FormTest3 : Form { public FormTest3() { InitializeComponent(); } private void FormTest3_Load(object sender, EventArgs e) { this.dataGridView1.AutoGenerateColumns = false; ; this.dataGridView1.MouseClick += dataGridView1_MouseClick; this.dataGridView1.Rows.Add(); } /// <summary> /// stripItem0點擊事件-刪除選中行 /// </summary> private void stripItems0_Click(object sender, EventArgs e) { MessageBox.Show("-刪除選中行--"); } private void dataGridView1_MouseClick(object sender, MouseEventArgs e) { ContextMenuStrip strip = new ContextMenuStrip(); strip.ShowImageMargin = false;//設置右擊菜單屬性 strip.Items.Add("刪除選定行"); strip.Items.Add("添加行"); strip.Items[0].Click += stripItems0_Click;//彈出菜單第一項點擊事件 strip.Items[1].Click += stripItems1_Click;//彈出菜單第二項點擊事件 if (e.Button == MouseButtons.Right)//右鍵點擊 { strip.Show(this.dataGridView1, e.Location);//彈出菜單 } } /// <summary> /// 彈出菜單第二項點擊事件 /// </summary> private void stripItems1_Click(object sender, EventArgs e) { MessageBox.Show("-添加行-"); } }}
解釋:主要方法是:dataGridView1_MouseClick,這邊判斷是否右鍵點擊【操做請在datagridview裏面右鍵點擊】。代碼在FormTest3.cs裏面,進入連接在最下面。【其實這種思惟更適合客戶端,網頁和桌面應用仍是有區別的】spa

1.3 方式三
是我參考網上一些固有樣式,寫出的一個動態的操做列,能夠適合權限管理【按鈕】。推薦使用。固然可能有些小問題,暫時我還沒發現。這種樣式和後端管理的操做列相似。若是按鈕超出列的寬度,請設置合適的該列的寬度。3d
using chao.net.UIL;using chao.net.UIL.UserControls;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 chao.net{ public partial class FormTest : Form { public FormTest() { InitializeComponent(); } private void FormTest_Load(object sender, EventArgs e) { this.dataGridView1.AutoGenerateColumns = false; DataGridViewActionButtonColumn dataGridViewColumn = new DataGridViewActionButtonColumn(); dataGridViewColumn.Width = 240; dataGridViewColumn.HeaderText = "操做列2"; dataGridViewColumn.Resizable = DataGridViewTriState.False; this.dataGridView1.Columns.Add(dataGridViewColumn); /* DataGridViewDetailButtonColumn buttonColumn = new DataGridViewDetailButtonColumn(); buttonColumn.HeaderText = "操做列3"; this.dataGridView1.Columns.Add(buttonColumn);*/ this.dataGridView1.Rows.Add(); /* this.dataGridView1.RowHeadersVisible = true; this.dataGridView1.ColumnHeadersVisible = true;*/ } private void dataGridView1_CellMouseClick(object sender, DataGridViewCellMouseEventArgs e) { if (this.dataGridView1.Columns[e.ColumnIndex].HeaderText == "操做列2") { DataGridViewActionButtonColumn dataGridViewColumn = (DataGridViewActionButtonColumn)this.dataGridView1.Columns[e.ColumnIndex]; //DataGridViewActionButtonCell dataGridViewActionButtonCell = (DataGridViewActionButtonCell)dataGridViewColumn.CellTemplate; List<ActionButton> buttonList = dataGridViewColumn.ButtonList; foreach(ActionButton act in buttonList){ if (act.MouseOnButton)//此時鼠標懸浮在上面 { Console.WriteLine("點擊了:" + act.Name); //MessageBox.Show("點擊了:"+act.Name); } } } } }}
解釋:主要方法是:FormTest_Load 和 dataGridView1_MouseClick,FormTest_Load 主要是自定義單元格,dataGridView1_MouseClick是點擊判斷點擊的按鈕區域進而作業務處,須要使用自定義的列DataGridViewActionButtonColumn和自定義的單元格**DataGridViewActionButtonCell。**代碼在FormTest.cs裏面,進入連接在最下面。【其實這種思惟更適合客戶端,網頁和桌面應用仍是有區別的】code
