Compare value of datagrid with value selected from database
May 24 2014 8:04 AM
Hi ;
I fill to grid with excel data and want to compare if value exists on database or not ?
for (int i = 0; i < dataGridView1.RowCount; i++)
if (radioButton1.Checked==true)
{
string strConn = @"Data Source='" + dbconfig.tb1 + "';Initial Catalog='" + dbconfig.tb2 + "';user='" + dbconfig.tb3 + "';pwd='" + dbconfig.tb4 + "'";
SqlConnection conn = new SqlConnection(strConn);
conn.Open();
SqlCommand cmd = new SqlCommand("SELECT CODE FROM LG_" + dbconfig.tb5 + "_TABLE WHERE CODE NOT LIKE '" + dataGridView1.Rows[i].Cells[0].Value + "'", conn);
cmd.ExecuteNonQuery();
SqlDataReader reader = cmd.ExecuteReader();
if(reader.Read())
{
MessageBox.Show("Check ITEMS" + reader[i].ToString());
}
conn.Close();
}
