WinForm中DataGridView添加,删除,修改操作具体方法

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);
}
}
}
