DataGridView修改后直接保存到数据库程序

C#中DataGridView修改后直接保存到数据库实例程序，绝对可用，内附源码，有注释 主要代码: //单元格编辑结束后触发 private void dataGridView1_CellEndEdit_1(object sender, DataGridViewCellEventArgs e) { try { string rowid = this.dataGridView1.Rows[e.RowIndex].Cells[0].Value.ToString(); string cellhead = dataGridView1.Columns[e.ColumnIndex].DataPropertyName; string cellvalue = this.dataGridView1.Rows[e.RowIndex].Cells[e.ColumnIndex].Value.ToString(); if (cellhead == "domain") { cellhead = "[domain]"; } else { } if (cellvalue == "True" && cellhead == "passed") { cellvalue = "1"; } else { if (cellhead == "passed") { cellvalue = "0"; } else { } } string sqlcmd = "update domain_info set " + cellhead + "='" + cellvalue + "' where id=" + rowid; if (dbo.DBcmd(sqlcmd)) { resultshow.Text = " 编辑成功"; } else { resultshow.Text = " 编辑失败"; } } catch { MessageBox.Show("异常", "错误"); } }
