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

View Code

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         }
