Do you avoid using one form for data entry?

Combining data entry and find navigation is a mistake. I think 2 forms are better than one. I prefer a list box on one form with "Add", "Edit" and "Delete" buttons to a popup form. Rather than a listbox and the data entry fields on one form.

✅ Figure: Good Example - ListView with only 'Add' 'Edit' 'Delete' buttons

When you want to create a new entry or edit one, just click the buttons and open a new form with all the data entry fields.
