Please try below code ...

SQL

SqlDataAdapter da4 = new SqlDataAdapter("select rate_km,rate_day from vehicle_category where vehicle_name='" + ddlvnameri.SelectedValue +"' and vehicle_type='"+ ddlvtype.SelectedValue +"' ",con);
DataTable dt4 = new DataTable();
DataRow[] dr;

Note: You cann't use '&&' operator in Sql queries, instead use 'and' operator..
Also for '||' operations use 'OR' operator..

hay frnds,
Try These..

string query = "select rate_km,rate_day from vehicle_category where vehicle_name='" + ddlvnameri.SelectedValue +"' && vehicle_type='"+ ddlvtype.SelectedValue +"' ";

MySqlDataAdapter da = new MySqlDataAdapter(query, connection);<p.>
DataTable dtb = new DataTable();

da.Fill(dtb);

if (dtb.Rows.Count > 0)
{
txtrate.Text=dtb.Rows[0][0].ToString().Trim();
}

Solution 2

SqlDataAdapter da = new SqlDataAdapter(" select * from newtable ", con);
DataTable dt = new DataTable();
da.Fill(dt);
DataRow dr = dt.Rows[0];
txtrate.Text = dr["site"].ToString();
