我是靠谱客的博主专一大树，最近开发中收集的这篇文章主要介绍C# DataGridView中实现勾选存储数据和右键删除数据(示例代码)，觉得挺不错的，现在分享给大家，希望可以做个参考。

概述

DataGridView事件CellContentClick

触发dataGridView的CellContentClick事件，并且在事件中调用Edit 方法。
实现DataGridView中添加CheckBox后不满足条件去掉勾选
并且实现勾选后将绑定数据的存入表的动作

点击确定后去掉勾选

Main.cs

 private void tabControl1_SelectedIndexChanged(object sender, EventArgs e)
        {
            switch (this.tabControl1.SelectedIndex)
            {
                //case 0:
                //    //显示数据
                //    ShowVlues();
                //    break;

                case 1:
                   
                    TableDefine.Initial_TableE();
                    for (int i = 0; i <= TableDefine.tGridField.Length - 1; i++)
                    {
                        cboSearch.Items.Add(TableDefine.tGridField[i].sCaption);
                        cboSearchList.Items.Add(TableDefine.tGridField[i].sFieldName);
                    }
                    if (cboSearch.Items.Count > 0)
                    {
                        cboSearch.SelectedIndex = 0;
                    }
                    //取机种

                if (gvDataE.Columns.Contains(sGridField))
                {
                    gvDataE.Columns[sGridField].HeaderText = TableDefine.tGridField[i].sCaption;

            }
            gvDataE.Focus();
            //为dgv增加复选框列
            DataGridViewCheckBoxColumn checkbox = new DataGridViewCheckBoxColumn();

                }
            }
        }
        //点击勾选事件后进行数据绑定

                MessageBox.Show("机种、流程、站点不能为空，请检查!");
                //DataGridViewCheckBoxCell checkCell = (DataGridViewCheckBoxCell)this.gvDataE.Rows[e.RowIndex].Cells["IsChecked"];

                {
                    checkCell.Value = true;
                    //添加权限
                    fslConn.SaveFslPower(gvFunName, gvFunNameDesc, Model,StationType, StationTypeDesc);
                }
            }
        }

ComboBox取值

main.cs
 //取机种
                    DataTable ModelDT = fslConn.GetAllModel();
                    if (ModelDT.Rows.Count > 0)
                    {
                        foreach (DataRow item in ModelDT.Rows)
                        {
                            cboModel.Items.Add(item[0]);
                        }
                    }
 fslConn.cs                   
 //取机种
        public DataTable GetAllModel()
        {
            return fslDAL.GetAllModel();
        }
fslDAL.cs
 //取机种
        public DataTable GetAllModel()
        {
            string sql = "SELECT MODEL FROM IMES.M_MODEL";
            return utility.Query(sql);
        }

储存数据

 fslConn.cs  
    public long SaveFslPower(string gvFunName, string gvFunNameDesc, string Model, string StationType, string StationTypeDesc )
        {    
            return fslDAL.SaveFslPower(gvFunName, gvFunNameDesc, Model, StationType, StationTypeDesc);
        }
fslDAL.cs
     //存权限
        public long SaveFslPower(string gvFunName, string gvFunNameDesc, string Model, string StationType, string StationTypeDesc)
        {
            string id = GetMaxId();
            string sql = @"INSERT INTO IMES.M_STATIONTYPE_PARTSPEC  (ID,MODEL,STATION_TYPE,STATION_DESC,KP_SPEC,KP_SPEC_DESC,QTY,ENABLED,CREATE_EMPNO,CREATE_TIME,UPDATE_EMPNO)
                        VALUES(:1,:2,:3,:4,:5,:6,:7,:8,:9,:10,:11)";
            object[] para = new object[] { id, Model, StationType , StationTypeDesc,gvFunName, gvFunNameDesc, "1", "Y", utility.GlobalUserNo,DateTime.Now, utility.GlobalUserNo };
            return utility.ExecuteSql(sql, para);
        }

右键删除数据

实现效果

Main.cs
   //实现DataGridView栏位右键删除数据
        private void 删除ToolStripMenuItem_Click(object sender, EventArgs e)
        {
            if (gvData.Rows.Count == 0 || gvData.CurrentRow == null)
            {
                return;
            }
            string ID = gvData.CurrentRow.Cells["ID"].Value.ToString();
            if (MessageBox.Show("ID:" + ID + " 确认删除吗?", "提示", MessageBoxButtons.YesNo, MessageBoxIcon.Question) == DialogResult.Yes)
            {
                //M_STATIONTYPE_PARTSPEC_HT写入历史库
                fslConn.SaveFslHistoryData(ID);
                移除权限
                fslConn.DeleteFslByIDAndFunc(ID);

                //显示数据
                ShowVlues();
            }              
        }
fslConn.cs 
    //删除权限
        public long DeleteFslByIDAndFunc(string id)
        {
            return fslDAL.DeleteFslByIDAndFunc( id);
        }   
fslDAL.cs
     //删除权限
        public long DeleteFslByIDAndFunc(string id)
        {
            string sql = @"Delete from  IMES.M_STATIONTYPE_PARTSPEC WHERE ID =:1";
            object[] para = new object[] { id };
            return utility.ExecuteSql(sql, para);
        }
