C # Stop a person from entering options in the combo box dropdown

Question

I have a combo box with elements inside, just wonders if it is possible to stop people from entering it and allow them to only select an element that is already there?

Answer 1

Set DropDownStyleto DropDownList.

Answer 2

Winforms:

---

comboBox.DropDownStyle = ComboBoxStyle.DropDownList;

WPF:

---

comboBox.IsReadOnly = true;
comboBox.IsEditable = false;

Answer 3

The rest cut out the WinForms combo box; for completeness, in WPF you need to install IsReadOnly = trueand IsEditable = false.
