pageload事件里面的绑定 ，有数据的话读数据库绑定就行。注释部分去掉的话就会自带一行空白行

protected void bind()
        {
                DataTable table = new DataTable();
                table.Columns.Add(new DataColumn("ID"));
                table.Columns.Add(new DataColumn("起年月"));
                table.Columns.Add(new DataColumn("止年月"));
                table.Columns.Add(new DataColumn("学校名称"));
                table.Columns.Add(new DataColumn("专业"));
                table.Columns.Add(new DataColumn("学历"));
                //DataRow row = table.NewRow();
                //row["ID"] = Guid.NewGuid().ToString();
                //table.Rows.Add(row);
                GridView1.DataSource = table;
                GridView1.DataBind();
        }

教育背景相关操作 代码

#region ===教育背景===

        protected void lbtnAddRow_Click(object sender, EventArgs e)
        {
            DataTable table = GetGridViewData1();
            DataRow newRow = table.NewRow();
            newRow["ID"] = Guid.NewGuid().ToString();
            table.Rows.Add(newRow);
            GridView1.DataSource = table;
            GridView1.DataBind();
        }

        private DataTable GetGridViewData1()
        {
            DataTable table = new DataTable();
            table.Columns.Add(new DataColumn("ID"));
            table.Columns.Add(new DataColumn("起年月"));
            table.Columns.Add(new DataColumn("止年月"));
            table.Columns.Add(new DataColumn("学校名称"));
            table.Columns.Add(new DataColumn("专业"));
            table.Columns.Add(new DataColumn("学历"));
            foreach (GridViewRow row in GridView1.Rows)
            {
                DataRow sourseRow = table.NewRow();
                sourseRow["ID"] = row.Cells[0].Text;
                sourseRow["起年月"] = ((TextBox)row.Cells[2].FindControl("JybjStarTime")).Text;
                sourseRow["止年月"] = ((TextBox)row.Cells[2].FindControl("JybjFinishTime")).Text;
                sourseRow["学校名称"] = ((TextBox)row.Cells[3].FindControl("SchoolName")).Text;
                sourseRow["专业"] = ((TextBox)row.Cells[4].FindControl("Major")).Text;
                sourseRow["学历"] = ((TextBox)row.Cells[5].FindControl("Education")).Text;
                table.Rows.Add(sourseRow);
            }
            return table;
        }

        protected void btnDeleteRow_Click(object sender, EventArgs e)
        {
            DataTable table = GetGridViewData1();
            foreach (GridViewRow row in GridView1.Rows)
            {
                if (((HtmlInputCheckBox)row.Cells[1].FindControl("chkRow")).Checked)
                {
                    foreach (DataRow dtRow in table.Rows)
                    {
                        if (dtRow["ID"].ToString() == row.Cells[0].Text)
                        {
                            table.Rows.Remove(dtRow);
                            break;
                        }
                    }
                }
            }
            GridView1.DataSource = table;
            GridView1.DataBind();
        }

        #endregion

保存的话调用一下GetGridViewData1()方法，会返回data table 然后 调用table存数据库就行

DataTable table = GetGridViewData1();
                if (table.Rows.Count > 0)
                {
                    for (int i = 0; i < table.Rows.Count; i++)
                    {
                        string sql = "insert into 教育背景 values('" + table.Rows[i]["ID"].ToString() + "','" + table.Rows[i]["起年月"].ToString() + "','" + table.Rows[i]["止年月"].ToString() + "','" + table.Rows[i]["学校名称"].ToString() + "','" + table.Rows[i]["专业"].ToString() + "','" + table.Rows[i]["学历"].ToString() + "','" + ID + "')";
                        db.db.ExecuteSql(sql);
                    }
                }
