[WinForm]DataGridView添加，删除，修改操作_.NET_编程开发_程序员俱乐部

1.添加操作，代码如下：

class="csharpcode">        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()));
            }
        }

        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);
                }
            }
        }
