SqlDataReader sdr = cmd_Supply.ExecuteReader(CommandBehavior.CloseConnection);
sdr.Read();


Supply_type.SelectedValue = sdr[ "Supply_type "].ToString();

string aaa = sdr[ "Supply_medicare "].ToString();

if (aaa == "是 ")
{
RadioButton6.Checked = true;
RadioButton7.Checked = false;
}

sdr[ "Supply_medicare "].ToString().Trim();
