Read the error message - it's pretty explicit.

The OdbcConnection object is not open.

That means that you have created an instance, and either tried to open it but the operation failed (and you swallowed the exception), you didn't try to open it, or you opened it then subsequently closed it again.

Without your code, there isn't a lot we can add to that...

Your code should look something like this:
using (OdbcConnection con = new OdbcConnection(strConnect))
    {
    con.Open();
    using (OdbcCommand cmd = new OdbcCommand("SELECT Age, Description FROM myTable WHERE ID = @ID", con))
        {
        cmd.Parameters.AddWithValue("@ID", myTextBox.Text);
        using (OdbcDataReader reader = cmd.ExecuteReader())
            {
            while (reader.Read())
                {
                int age = (int) reader["Age"];
                string desc = (string) reader["Description"];
                Console.WriteLine($"{age}\n{desc}");
                }
            }
        }
    }
