Winform DataGridView列的单元格中动态添加图片和文字

先上图在说，第二列中图片和文字的样式

1、需要重写DataGridViewTextBoxColumn，新建类TextAndImageColumn.cs

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

 namespace DataGridViewTest
 {
     public class TextAndImageColumn : DataGridViewTextBoxColumn
     {
         private Image imageValue;
         private Size imageSize;

         public TextAndImageColumn()
         {
             this.CellTemplate = new TextAndImageCell();
         }

         public override object Clone()
         {
             TextAndImageColumn c = base.Clone() as TextAndImageColumn;
             c.imageValue = this.imageValue;
             c.imageSize = this.imageSize;
             return c;
         }

         public Image Image
         {
             get { return this.imageValue; }
             set
             {
                 if (this.Image != value)
                 {
                     this.imageValue = value;
                     this.imageSize = value.Size;

                     if (this.InheritedStyle != null)
                     {
                         Padding inheritedPadding = this.InheritedStyle.Padding;
                         this.DefaultCellStyle.Padding = new Padding(imageSize.Width,
                     inheritedPadding.Top, inheritedPadding.Right,
                     inheritedPadding.Bottom);
                     }
                 }
             }
         }
         private TextAndImageCell TextAndImageCellTemplate
         {
             get { return this.CellTemplate as TextAndImageCell; }
         }
         internal Size ImageSize
         {
             get { return imageSize; }
         }
     }

     public class TextAndImageCell : DataGridViewTextBoxCell
     {
         private Image imageValue;
         private Size imageSize;

         public override object Clone()
         {
             TextAndImageCell c = base.Clone() as TextAndImageCell;
             c.imageValue = this.imageValue;
             c.imageSize = this.imageSize;
             return c;
         }

         public Image Image
         {
             get
             {
                 if (this.OwningColumn == null ||
            this.OwningTextAndImageColumn == null)
                 {

                     return imageValue;
                 }
                 else if (this.imageValue != null)
                 {
                     return this.imageValue;
                 }
                 else
                 {
                     return this.OwningTextAndImageColumn.Image;
                 }
             }
             set
             {
                 if (this.imageValue != value)
                 {
                     this.imageValue = value;
                     this.imageSize = value.Size;

                     Padding inheritedPadding = this.InheritedStyle.Padding;
                     this.Style.Padding = new Padding(imageSize.Width,
                    inheritedPadding.Top, inheritedPadding.Right,
                    inheritedPadding.Bottom);
                 }
             }
         }
         protected override void Paint(Graphics graphics, Rectangle clipBounds,
        Rectangle cellBounds, int rowIndex, DataGridViewElementStates cellState,
        object value, object formattedValue, string errorText,
        DataGridViewCellStyle cellStyle,
        DataGridViewAdvancedBorderStyle advancedBorderStyle,
        DataGridViewPaintParts paintParts)
         {
             // Paint the base content
             base.Paint(graphics, clipBounds, cellBounds, rowIndex, cellState,
               value, formattedValue, errorText, cellStyle,
               advancedBorderStyle, paintParts);

             if (this.Image != null)
             {
                 // Draw the image clipped to the cell.
                 System.Drawing.Drawing2D.GraphicsContainer container =
                graphics.BeginContainer();

                 graphics.SetClip(cellBounds);
                 graphics.DrawImageUnscaled(this.Image, cellBounds.Location);

                 graphics.EndContainer(container);
             }
         }

         private TextAndImageColumn OwningTextAndImageColumn
         {
             get { return this.OwningColumn as TextAndImageColumn; }
         }
     }
 }

2、新建窗体Form1.cs，拖控件DataGridView到窗体，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.Windows.Forms;
 using System.Data.SqlClient;

 namespace DataGridViewTest
 {
     public partial class Form1 : Form
     {
         private static string imagePath = AppDomain.CurrentDomain.BaseDirectory.Substring(, AppDomain.CurrentDomain.BaseDirectory.IndexOf("bin")) + "Images\\";//列表图片路径
         public Form1()
         {
             InitializeComponent();
             InitControlsProperties();
         }

         private void InitControlsProperties()
         {
             this.dataGridView1.AutoGenerateColumns = false;
             TextAndImageColumn ColumnRoleID = new TextAndImageColumn();
             ColumnRoleID.DataPropertyName = "RoleID";
             ColumnRoleID.DefaultCellStyle.Alignment = DataGridViewContentAlignment.MiddleLeft;
             ColumnRoleID.Name = "RoleID";
             ColumnRoleID.HeaderText = "权限ID";
             ColumnRoleID.Width = ;
             this.dataGridView1.Columns.Add(ColumnRoleID);

             this.dataGridView1.AutoGenerateColumns = false;
             TextAndImageColumn ColumnRoleName = new TextAndImageColumn();
             ColumnRoleName.DataPropertyName = "RoleName";
             ColumnRoleName.DefaultCellStyle.Alignment = DataGridViewContentAlignment.MiddleLeft;
             ColumnRoleName.Name = "RoleName";
             ColumnRoleName.HeaderText = "权限名称";
             ColumnRoleName.Width = ;
             this.dataGridView1.Columns.Add(ColumnRoleName);

             this.dataGridView1.AutoGenerateColumns = false;
             TextAndImageColumn ColumnDescription = new TextAndImageColumn();
             ColumnDescription.DataPropertyName = "Description";
             ColumnDescription.DefaultCellStyle.Alignment = DataGridViewContentAlignment.MiddleLeft;
             ColumnDescription.Name = "Description";
             ColumnDescription.HeaderText = "描述";
             ColumnDescription.Width = ;
             this.dataGridView1.Columns.Add(ColumnDescription);
         }

         private void Form1_Load(object sender, EventArgs e)
         {
             string strConn = "Data Source=XIAN-PC;Initial Catalog=ReportServer;Persist Security Info=True;User ID=sa;Password=sa";
             SqlConnection conn = new SqlConnection(strConn);
             string strSql = "select * from Roles";
             SqlCommand cmd = new SqlCommand(strSql, conn);
             SqlDataAdapter adapter = new SqlDataAdapter(cmd);
             DataSet ds = new DataSet();
             conn.Open();
             adapter.Fill(ds, "Roles");
             conn.Close();
             this.dataGridView1.DataSource = ds.Tables["Roles"];
         }

         private void dataGridView1_CellFormatting(object sender, DataGridViewCellFormattingEventArgs e)
         {
             #region 第二列
             if (e.ColumnIndex == )
             {
                 TextAndImageCell cell = dataGridView1.Rows[e.RowIndex].Cells[e.ColumnIndex] as TextAndImageCell;
                 if (cell != null && e.Value != null)
                 {
                     try
                     {
                         string ajzt = cell.Value.ToString();
                         string path = imagePath;
                         switch (ajzt)
                         {
                             case "发布者":
                                 path += "1.png";
                                 break;
                             case "浏览者":
                                 path += "2.png";
                                 break;
                             default:
                                 path += "3.png";
                                 break;
                         }
                         cell.Image = GetImage(path);
                     }
                     catch (Exception ex)
                     {

                     }
                 }
             }
             #endregion
         }

         public System.Drawing.Image GetImage(string path)
         {
             return System.Drawing.Image.FromFile(path);
         }

     }
 }
