Body
Do not use string concatenation to build sql command text, use always a parameterized query <pre><code>query = "INSERT INTO mahasiswa VALUES (@p1,@p2,@p3);"; using(MySqlConnection koneksi = new MySqlConnection(connectionString)) using(MySqlCommand perintah = new MySqlCommand(query, koneksi)) { koneksi.Open(); perintah.Parameters.AddWithValue("@p1", txtnama.Text); perintah.Parameters.AddWithValue("@p2", txtjurusan.Text); perintah.Parameters.AddWithValue("@p3", txtemail.Text); int res = perintah.ExecuteNonQuery(); if (res == 1) MessageBox.Show("Input Data Sukses..."); else MessageBox.Show("Input Data Gagal... "); } </code></pre> If you use string concatenation your code will be open to sql injection where a malicious user could wreak havoc with your database (<a href="https://stackoverflow.com/questions/332365/how-does-the-sql-injection-from-the-bobby-tables-xkcd-comic-work">Look at this funny example</a>) Also your format statement is totally wrong, I doubt that your code reaches the point where the database command is executed because you list the arguments for string.Format from the index 1 to index 3 and you supply 3 arguments, but the index should start from zero and end at two. So you should get an exception on that line. Another point to keep note is the <a href="http://msdn.microsoft.com/en-us/library/yh598w02%28v=VS.80%29.aspx" rel="nofollow noreferrer">using statement</a>. As you can see, in my code the using statement will ensure the proper closing and disposing of the connection and command objects. The connection is particularly important to dispose properly because a failure here could break your program later.

Guidance

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
