DataGridview动态添加列

1.获取数据源（select * from table名称）

2.动态绑定数据源

 1  private void GetTableInfo(DataTable dt)

 2         {

 3             listBh = new List<BH_DICTInfo>();

 4             foreach (DataRow dr in dt.Rows)

 5             {

 6                 BH_DICTInfo model = new BH_DICTInfo();

 7                 model.DictId = dr["DICT_ID"].ToString();

 8                 model.DictName = dr["DICT_NAME"].ToString();

 9                 model.DictType = dr["DICT_TYPE"].ToString();

10                 model.Enable = Convert.ToDecimal(dr["ENABLE"].ToString());

11                 model.Orders = Convert.ToDecimal(dr["ORDERS"].ToString());

12                 model.Remark = dr["REMARK"].ToString();

13                 listBh.Add(model);

14             }

15             dgvBh.DataSource = listBh;

16             //清除上次数据源

17             this.dgvBh.Columns.Clear();

18             //属性时是否自动创建列

19             dgvBh.AutoGenerateColumns = false;

20 

21             DisplayCol(dgvBh, "DictId", "字典编号");

22             DisplayCol(dgvBh, "DictName", "字典名称");

23             DisplayCol(dgvBh, "DictType", "字典类型");

24             DisplayCol(dgvBh, "Orders", "字典名称");

25             DisplayCol(dgvBh, "Enable", "是否可用");

26             DisplayCol(dgvBh, "Remark", "备注");

27             DisplayCol(dgvBh, "Checkbox", "删除");

28             //this.dgvBh.DataMember = "DictName,DictType,Orders,Enable,Remark";

29             this.dgvBh.Columns[0].Visible = false;

30         }

31         /// <summary>

32         /// 添加列表头

33         /// </summary>

34         /// <param name="dgv"></param>

35         /// <param name="dataPropertyName"></param>

36         /// <param name="headerText"></param>

37         void DisplayCol(DataGridView dgv, string dataPropertyName, string headerText)

38         {

39             //dgv.Columns[dataPropertyName].Width = 100;

40             if (dataPropertyName == "Checkbox")

41             {

42                 DataGridViewCheckBoxColumn ck = new DataGridViewCheckBoxColumn();

43                 ck.DataPropertyName = dataPropertyName;

44                 ck.HeaderText = headerText;

45                 ck.Name = dataPropertyName;

46                 dgv.Columns.AddRange(new DataGridViewColumn[] { ck });

47             }

48             else

49             {

50                 DataGridViewTextBoxColumn obj = new DataGridViewTextBoxColumn();

51                 obj.DataPropertyName = dataPropertyName;

52                 obj.HeaderText = headerText;

53                 obj.Name = dataPropertyName;

54                 obj.Resizable = DataGridViewTriState.True;

55                 obj.ReadOnly = true;

56                 dgv.Columns.AddRange(new DataGridViewColumn[] { obj });

57             }

58         }

3.获取选中的行

 #region 修改事件

        /// <summary>

        /// 修改事件

        /// </summary>

        /// <param name="sender"></param>

        /// <param name="e"></param>

        private void btnBh_update_Click(object sender, EventArgs e)

        {

            model = new BH_DICTInfo();

            foreach (DataGridViewRow row in this.dgvBh.SelectedRows)

            {

                model.DictId = row.Cells["DictId"].Value.ToString();

                model.DictName = row.Cells["DictName"].Value.ToString();

                model.DictType = row.Cells["DictType"].Value.ToString();

                model.Enable = Convert.ToDecimal(row.Cells["Enable"].Value.ToString());

                model.Orders = Convert.ToDecimal(row.Cells["Orders"].Value.ToString());

                model.Remark = row.Cells["Remark"].Value.ToString();

            }

            if (model == null)

                MessageBox.Show("请选择");

            BhDictAddEdit SysEdit = new BhDictAddEdit("业务字典编辑信息", "保存编辑", model);

            SysEdit.ShowDialog();

            BindDataBh();

        }

        #endregion

4.删除多行操作

 1   #region 删除事件

 2         /// <summary>

 3         ///删除事件

 4         /// </summary>

 5         /// <param name="sender"></param>

 6         /// <param name="e"></param>

 7         private void btnBh_delete_Click(object sender, EventArgs e)

 8         {

 9             //动态添加链接对象语句

10             StringBuilder sqlStr = new StringBuilder();

11             for (int i = 0; i < dgvBh.Rows.Count; i++)

12             {

13                 object cbh = this.dgvBh.Rows[i].Cells["Checkbox"].Value;

14                 if (cbh != null)

15                 {

16                     sqlStr.Append("DICT_ID=");

17                     sqlStr.Append("\'");

18                     sqlStr.Append(this.dgvBh.Rows[i].Cells["DictId"].Value.ToString());

19                     sqlStr.Append("\'");

20                     sqlStr.Append(" or ");

21                 }

22             }

23 

24             if (sqlStr.ToString() != "")

25             {

26                 string sq = sqlStr.ToString().Substring(0, sqlStr.ToString().TrimEnd().LastIndexOf("or"));

27 

28                 if (DevExpress.XtraEditors.XtraMessageBox.Show("您确定要删除吗？", "系统提示") == System.Windows.Forms.DialogResult.OK)

29                // if (MessageBox.Show("您确定要删除吗？", "系统提示", MessageBoxButtons.YesNo, MessageBoxIcon.Information) == System.Windows.Forms.DialogResult.Yes)

30                 {

31                     string sql = "delete from bh_dict where " + sq + "";

32                     ParameterSetConfig.GetDataDal();

33                     ParameterSetConfig.OpenDB();

34                     DataTable dt = ParameterSetConfig._dataDal.ExecuteSqlReturnTable(sql);

35                     ParameterSetConfig.closeDB();

36                     BindDataBh();

37                 }

38             }

39             else

40             {

41                 MessageBox.Show("请选择要删除的行");

42             }

43         }
