1、窗体加载时初始化grid

private void LayOut() {

dgv.Font = new System.Drawing.Font("微软雅黑", 9F);
dgv.AutoGenerateColumns = false;
dgv.AllowUserToAddRows = false;
dgv.AllowUserToResizeColumns = true;
dgv.AllowUserToOrderColumns = true;

DataGridViewCheckBoxColumn checkBoxColumn = new DataGridViewCheckBoxColumn();
checkBoxColumn.Width = 40;
checkBoxColumn.Name = "Check";
checkBoxColumn.HeaderText = "全选";
dgv.Columns.Add(checkBoxColumn);

CommonUtil.AddDgvColumns2(dgv, "id", "ID", 110);
CommonUtil.AddDgvColumns2(dgv, "name", "名称", 0, false);
CommonUtil.AddDgvColumns(dgv, "Img", "照片", 90);

}

2、添加公共类

//公共类
public class CommonUtil{
public static void AddDgvColumns(DataGridView dgv, string dgvName, string dgvHeadertext, int dgvWidth = 50, bool dgvVisible = true, bool dgvReadonly = true, bool _Frozen = false)
{
　　if (dgvName == "Img")
　　{
　　　　DataGridViewImageColumn column = new DataGridViewImageColumn();
　　　　column.ImageLayout = DataGridViewImageCellLayout.Zoom;
　　　　column.Name = dgvName;
　　　　column.DataPropertyName = dgvName;
　　　　column.HeaderText = dgvHeadertext;
　　　　column.Width = dgvWidth;
　　　　column.Visible = dgvVisible;
　　　　column.Frozen = _Frozen;//是否冻结
　　　　dgv.Columns.Add(column);
　}
 else
 {
　　 　　dgvWidth = dgvWidth < 2 ? 2 : dgvWidth;
　　　　DataGridViewColumn column = new DataGridViewTextBoxColumn();
　　　　column.Frozen = _Frozen;//是否冻结
　　　　column.AutoSizeMode = DataGridViewAutoSizeColumnMode.Fill;
　　　　column.HeaderCell.Style.Alignment = DataGridViewContentAlignment.MiddleCenter;
　　　　column.ReadOnly = dgvReadonly;
　　　　column.Name = dgvName;
　　　　column.DataPropertyName = dgvName;
　　　　column.HeaderText = dgvHeadertext;
　　　　column.Width = dgvWidth;
　　　　column.Visible = dgvVisible;
　　　　column.MinimumWidth = dgvWidth;
//column.SortMode = DataGridViewColumnSortMode.NotSortable;
　　　　dgv.Columns.Add(column);
　　}
}


     public static void AddDgvColumns2(DataGridView dgv, string dgvName, string dgvHeadertext, int dgvWidth = 50, bool dgvVisible = true, bool dgvReadonly = true, bool _Frozen = false)
        {
            dgvWidth = dgvWidth < 2 ? 2 : dgvWidth;
            DataGridViewColumn column = new DataGridViewTextBoxColumn();
            column.Frozen = _Frozen;//是否冻结
            column.AutoSizeMode = DataGridViewAutoSizeColumnMode.None;
           
            column.ReadOnly = dgvReadonly;
            column.Name = dgvName;
            column.DataPropertyName = dgvName;
            column.HeaderText = dgvHeadertext;
            column.Width = dgvWidth;
            column.Visible = dgvVisible;
            column.MinimumWidth = dgvWidth;
            if (!dgvReadonly)
            {
                column.HeaderText = dgvHeadertext + "*";
            }
            //column.SortMode = DataGridViewColumnSortMode.NotSortable;
            dgv.Columns.Add(column);
        }
}

 3、数据绑定

private void LoadList(){
　　string sql="select * from user";
　　DataSet ds=new DataSet();
 　　SqlHelper.ExecuteDataSet(ref ds, sql); 
　　DataTable dt2 = ds.Tables[1];
     dt.Columns.Add("Img", typeof(Image));
      dgv.Columns["Img"].DefaultCellStyle.NullValue = null;
      dgv.DataSource = dt2;
            for (int i = 0; i < dgv.RowCount; i++)
            {
                string imgpath = dgv.Rows[i].Cells["imgUrl"].Value.ToString();
                dgv.Rows[i].Cells["Img"].Value = CommonUtil.GetFtpImage(imgpath);//获取照片对象
            }
}

 

分页使用别的方式
