[WinForm]DataGridView添加，删除，修改操作

1.添加操作，代码如下：

        IList<SelfRun> selfRunConfigs = new List<SelfRun>();

        private void btnNewConfig_Click(object sender, EventArgs e)

        {

            try

            {

                string _lampNo = UpDownSelfLampNo.Value.ToString();

                int _ctrlGpNo = Convert.ToInt16(UpDownCtrlGpCnt.Value);

                string _opWay = string.Format("{0}", rbConfig.Checked == true ? 1 : 0);

                string _opCtuch = GetSelectedCtuCh();

                if (CheckNewConfigIsLega(_ctrlGpNo, _opCtuch))

                {

                    string _opType = rbCgOpen.Checked == true ? "01" : rbCgClose.Checked == true ? "00" : "02";

                    selfRunConfigs.Add(new SelfRun(_opCtuch, _opType, Convert.ToInt32(UpDownTime.Value)));

                }

                BindGridViewForIList<SelfRun>(gcConfigShow, selfRunConfigs);

            }

            catch (Exception ex)

            {

                MessageBox.Show(string.Format("新增配置失败，原因:{0}", ex.Message.Trim()));

            }

        }

        private void BindGridViewForIList<T>(DataGridView gv, IList<T> datasource)

        {

            BindingList<T> _bindinglist = new BindingList<T>(datasource);

            BindingSource _source = new BindingSource(_bindinglist, null);

            gv.DataSource = _source;

        }

SelfRun实体类代码如下：

    public struct SelfRun

    {

        public SelfRun(string _opCtuCh, string _opWay, int _opTime)

            : this()

        {

            OpCtuCh = _opCtuCh;

            OpWay = _opWay;

            OpTime = _opTime;

        }

        public string OpCtuCh

        {

            get;

            set;

        }

        public string OpWay { get; set; }

        public int OpTime { get; set; }

    }

界面绑定，如图：

效果如图：

2.修改操作，代码如下：

其实思路很简单，就是点击行的时候，获取行内数据信息，然后填充到控件内，修改后，点击‘修改配置’后即可保存修改。

所以首先设置点击控件的时候，是选择一行，如图：

在CellClick事件中完成，当点击行的时候，将行数据填充到控件内，代码如下：

        private void gcConfigShow_CellClick(object sender, DataGridViewCellEventArgs e)

        {

            if (e.RowIndex < 0) return;

            DataGridView _dgv = (DataGridView)sender;

            string _opWay = _dgv.Rows[e.RowIndex].Cells["OpWay"].Value.ToString();

            switch (_opWay)

            {

                case "00":

                    ThreadSafeOpRadioButton(rbCgClose, true);

                    break;

                case "01":

                    ThreadSafeOpRadioButton(rbCgOpen, true);

                    break;

                case "02":

                    ThreadSafeOpRadioButton(rbSaveOne, true);

                    break;

            }

            string _opCtuch = _dgv.Rows[e.RowIndex].Cells["OpCtuCh"].Value.ToString();

            for (int i = 0; i < _opCtuch.Length; i++)

            {

                if (i == 0)

                    ThreadSafeCheckBox(ckch1, _opCtuch[i].Equals('1'));

                if (i == 1)

                    ThreadSafeCheckBox(ckch2, _opCtuch[i].Equals('1'));

                if (i == 2)

                    ThreadSafeCheckBox(ckch3, _opCtuch[i].Equals('1'));

                if (i == 3)

                    ThreadSafeCheckBox(ckch4, _opCtuch[i].Equals('1'));

                if (i == 4)

                    ThreadSafeCheckBox(ckch5, _opCtuch[i].Equals('1'));

                if (i == 5)

                    ThreadSafeCheckBox(ckch6, _opCtuch[i].Equals('1'));

                if (i == 6)

                    ThreadSafeCheckBox(ckch7, _opCtuch[i].Equals('1'));

                if (i == 7)

                    ThreadSafeCheckBox(ckch8, _opCtuch[i].Equals('1'));

            }

            string _opTime = _dgv.Rows[e.RowIndex].Cells["OpTime"].Value.ToString();

            decimal _time;

            if (decimal.TryParse(_opTime, out _time))

                ThreadSfeOpUpDown(UpDownTime, _time);

        }

点击修改按钮内代码如下：

        private void btnUpdateConfig_Click(object sender, EventArgs e)

        {

            try

            {

                if (CheckSelectedRow())

                {

                    int _rowIndex = gcConfigShow.CurrentCell.RowIndex;

                    int _ctrlGpNo = Convert.ToInt16(UpDownCtrlGpCnt.Value);

                    string _opWay = string.Format("{0}", rbConfig.Checked == true ? 1 : 0);

                    string _opCtuch = GetSelectedCtuCh();

                    string _opType = rbCgOpen.Checked == true ? "01" : rbCgClose.Checked == true ? "00" : "02";

                    SelfRun _selfRunByRowIndex = selfRunConfigs[_rowIndex];

                    _selfRunByRowIndex.OpCtuCh = GetSelectedCtuCh();

                    _selfRunByRowIndex.OpTime = Convert.ToInt32(UpDownTime.Value);

                    _selfRunByRowIndex.OpWay = _opType;

                    selfRunConfigs.RemoveAt(_rowIndex);

                    selfRunConfigs.Add(_selfRunByRowIndex);

                    BindGridViewForIList<SelfRun>(gcConfigShow, selfRunConfigs);

                }

            }

            catch (Exception ex)

            {

                MessageBox.Show(string.Format("修改配置失败，原因:{0}", ex.Message.Trim()));

            }

        }

3.删除操作，代码如下：

        private void btnDeleteConfig_Click(object sender, EventArgs e)

        {

            if (CheckSelectedRow())

            {

                if (MessageBox.Show("是否删除该行数据？", "消息", MessageBoxButtons.YesNo, MessageBoxIcon.Question) == DialogResult.Yes)

                {

                    selfRunConfigs.RemoveAt(gcConfigShow.CurrentCell.RowIndex);

                    BindGridViewForIList<SelfRun>(gcConfigShow, selfRunConfigs);

                }

            }

        }
