You technically have 3 forums, not two. You close the "inner" form but you never close the "outer" form. The simplest way to fix it is just call <code>Close</code> after you show the dialog for the "inner" form. <pre><code>if (dr.Read()) { if (this.CompareStrings(dr["SCSID"].ToString(), txtUser.Text) && this.CompareStrings(dr["SCSPass"].ToString(), txtPass.Text) && this.CompareStrings(dr["isAdmin"].ToString(), isAdmin)) { MessageBox.Show("Hello " + txtUser.Text, "Admin", MessageBoxButtons.OK, MessageBoxIcon.Information); var adminf = new Admin(txtUser.Text); this.Hide(); adminf.ShowDialog(); //This line blocks till you close the form this.Close(); // <--- NEW LINE } else if (this.CompareStrings(dr["SCSID"].ToString(), txtUser.Text) && this.CompareStrings(dr["SCSPass"].ToString(), txtPass.Text) && this.CompareStrings(dr["isAdmin"].ToString(), isNotAdmin)) { MessageBox.Show(string.Format("Welcome {0}", txtUser.Text)); var userf = new UserForm(txtUser.Text); this.Hide(); userf.ShowDialog(); //This line blocks till you close the form this.Close(); // <--- NEW LINE } } </code></pre> <hr> On a side note, you really need to be using <a href="https://stackoverflow.com/questions/5468425/how-do-parameterized-queries-help-against-sql-injection">Parametrized Queries</a>. If I decided to try to use the password <code>'; drop table SCSID; --</code> in your login form can you tell me what would happen? You also really should be using <code>using</code> statements around all objects that implement <code>IDisposable</code>. At a quick glance that would be <code>SqlConnection</code>, <code>SqlCommand</code>, and <code>SqlReader</code> but there may be more. Also if you are using a <code>using</code> statment you don't need to call <code>SCScon.Close();</code>

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.
