Data Source= ServerName; Initial Catalog=databasename; user id=yourid;password=yourpassword

user id and password is applicable if your sql server connect with Sql Server Authentication
if your sqlserver connect with windows authentication than user id and password is not require...........
Try this...
I hope it will be work

you need a mysql connector http://dev.mysql.com/downloads/connector/net/1.0.html[^]

donload from here then add reference in project

add this line in Proj
using MySql.Data.MySqlClient;

private void Form1_Load(object sender, EventArgs e)
{
//Set up connection string
string connString = @" server = localhost;
database = sujeetdb;
user id = root;
password =12345; ";
//Set up query string
string sql = @" select * from login ";
MySqlConnection conn=null ;
try
{
conn = new MySqlConnection(connString);
conn.Open();
MySqlCommand cmd = new MySqlCommand(sql, conn);
MySqlDataAdapter adap = new MySqlDataAdapter(cmd);
DataSet ds = new DataSet();
adap.Fill(ds);
dataGridView1.DataSource=ds.Tables[0];
}
catch (Exception ex)
{
Console.WriteLine("Error " + ex);
}
finally
{
conn.Close();
}
}
