C#教程之WinForm中DataGridView添加,删除,修改操作具体

1.添加操作，代码如下：

复制代码代码如下:

	
	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：

复制代码代码如下:

	
	    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：

复制代码代码如下:

	
	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：

复制代码代码如下:

	
	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：

复制代码代码如下:

	
	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);

	}

	}

	}
