我正在使用C＃.net开发一个winform应用程序，使用DataGridView来显示数据，但在上次更新后，DataGridView返回最后一行，但我想要{{1}返回一个空行或只显示标题...
nb：更新之前JmlKirimK值为1。
DataGridView这是我的 try
{
con.Close();
con.Open();
MySqlCommand cmd = new MySqlCommand("Select PasienID, NoHP, JmlKirimK from datapasien where JmlKirimK ='1' AND StatusDiabetes='Ya'", con);
DataTable dt = new DataTable();
MySqlDataAdapter da = new MySqlDataAdapter(cmd);
da.Fill(dt);
foreach (DataRow dr in dt.Rows)
{
con.Close();
con.Open();
nohp = Convert.ToString(dr[1]);
idpasien = Convert.ToString(dr[0]);
jml = Convert.ToString(dr[2]);
Cursor.Current = Cursors.WaitCursor;
if (objclsSMS.sendMsg(this.port2, nohp, this.txtisi.Text))
{
MySqlCommand cmd3 = new MySqlCommand("UPDATE datapasien SET JmlKirimK='2' Where PasienID='" + idpasien.Trim() + "'", con);
cmd3.ExecuteNonQuery();
terkirim = terkirim + 1;
showgridkirimulang();
}
else
{
tdkterkiri = tdkterkiri + 1;
}
showgridkirimreset();
}
con.Close();
alert.ContentImage = SmsGatewayProlanis.Properties.Resources.Warning1;
alert.CaptionText = "Status";
alert.ContentText = "Pesan Terkirim = " + terkirim + ", Pesan Tidak Terkirim = " + tdkterkiri;
alert.Show();
}
catch (Exception ex)
{
alert.ContentImage = SmsGatewayProlanis.Properties.Resources.Warning1;
alert.CaptionText = "Status";
alert.ContentText = ex.Message;
alert.Show();
ErrorLog(ex.Message);
}
