DataGridView批量修改数据
DataGridView 数据用List绑定的，在DataGridView第一列有个复选框，现在要将复选框选中的行数据批量修改？如何获得选中行的数据，并对数据进行批量的修改。有示例代码参考参考 --------------------编程问答-------------------- 判断DataGridView 是否有选择的项，更改值,保存DataGridViewfor(循环DataGridView 的值)
{
if(判断是否选中)
{
改值
}
}
保存DataGridView --------------------编程问答--------------------
foreach (DataGridViewRow dgvr in dgvBox.Rows)
{
DataGridViewCheckBoxCell checkCell = (DataGridViewCheckBoxCell)dgvr.Cells[0];
bool flag = Convert.ToBoolean(checkCell.Value);
if (flag)//如果此项被选中
{
string oid = dgvr.Cells[1].Value.ToString();
Ocean_OutStockRoom oos =new Ocean_OutStockRoom();
oos.OOSRID = int.Parse(oid);
oos.CheckPerson =Logon.CurrentUser.Name;
Ocean_OutStockRoomManager.ModifyOcean_OutStockRoomByOsidAndCheckPerson(oos,Logon.CurrentUser);
}
}
里面有类是自己的，改成你的行了 --------------------编程问答--------------------

for(int i = 0; i < this.dgvPayStyle.Rows.Count; i++)
{
if(this.dgvPayStyle.Rows[i].Cells["你复选框的列名"].EditedFormattedValue.ToString()== "True")
{
//做你要做的操作。
}
}

好。。。
补充：.NET技术 , C#
