    Hai,
    Try the below coding for login .This is one sample.Here I tried when the “user name and password” in the login form and database is same then your “first name” which is in the database will display in one label(here you can display user login page).

    protected void Button1_Click(object sender, EventArgs e)
    {
    string nname, npassword;
    nname = txtname.Text.ToString();
    npassword = txtpass.Text.ToString();

    //make a SQL connection
    SqlConnection con = new SqlConnection("your connection String")
    con.Open();
    SqlCommand cmd = new SqlCommand("SELECT FirstName FROM login WHERE (Username='" + nname + "' AND password='" + npassword + "')", con);
    DataTable dt = new DataTable();
    SqlDataAdapter adptr = new SqlDataAdapter(cmd);
    adptr.Fill(dt);
    if (dt.Rows.Count > 0)
    {
    DataRow dr1 = dt.Rows[0];
    Label1.Text = "Welcome";
    Label2.Text = dr1["FirstName"].ToString();
    }
    else
    Label2.Text = "Sorry,Invalid User name or password.........please try again";
    con.Close();
