如何在外部gridview Plz中的“单次更新"按钮(包括“编辑按钮")中编写代码(仅显示“更新按钮"，而不显示在“编辑按钮"中)更正代码

尊敬的专家，

Dear Experts,

protected void btnUpdae_Click(object sender, EventArgs e)
        {
       
          
            SqlDataAdapter daq;
            string connection = System.Configuration.ConfigurationManager.ConnectionStrings["MyDB"].ConnectionString;
            using (SqlConnection con = new SqlConnection(connection))
            {
                con.Open();
                daq = new SqlDataAdapter("update TextAnswers set Comments='" + grdView.Rows[1].Cells[5].Controls[0] + "', Marks=" + grdView.Rows[1].Cells[5].Controls[0] + " where Emp_ID=" + grdView.Rows[1].Cells[5].Controls[0] + "UserName='" + Request.QueryString["UserName"] + "'", con);
                SqlCommandBuilder sb = new SqlCommandBuilder(daq);
                sb.ConflictOption = ConflictOption.OverwriteChanges;

                daq.RowUpdated += new SqlRowUpdatedEventHandler(daq_RowUpdated);

                sb.ConflictOption = ConflictOption.CompareAllSearchableValues;

 
            }

          
        }
