    <p>I have a form in my program that has two drop downs and three buttons. When I run the form, I want the two drop downs to be blank, and one of the buttons to be disabled. I had this setup and working fine, but I have since been working on other classes and forms in the program and, coming back to refine some things, I have found that the code no longer works. The lines in particular are:</p> <pre><code>private void mainForm_Load(object sender, EventArgs e) { this.roomsTableAdapter.Fill(this.bookingSystemDatabaseDataSet.rooms); timeBox.ResetText(); roomBox.ResetText(); updateTextOutput(); bookButton.Enabled = false; } </code></pre> <p>The first line uses a TableAdapter to fill the associated 'rooms' drop down box, which works, however the code after this line does not seem to be executed at all. Commenting out the line means that they are executed, but obviously my 'rooms' drop down would be empty. I have tried moving the lines to the main execution point of the form, but the same thing happens.</p> <p>Furthermore, I have tried to fill the 'rooms' drop down in 'other ways', including:</p> <pre><code>roomBox.DataSource = roomsTableAdapter.Fill(bookingSystemDatabaseDataSet.rooms); </code></pre> <p>and:</p> <pre><code>roomsTableAdapter.Fill(bookingSystemDatabaseDataSet.rooms); roomBox.DataSource = roomsTableAdapter; </code></pre> <p>Of course, these attempts are very similar, but I figured I'd give it a shot. As it turns out, the exact same thing happens in each case; the 'roomBox' is filled, then the rest of the code is ignored. Debugging by stepping through backs up what I already thought to be true, the code is not even executed as far as I can tell. There are no errors, and the program runs, so why are these lines being ignored?</p>

    1. COReally can't see what's going wrong here. Whilst it's not a massive issue, I'd really appreciate any help you'd have to offer.

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.
