The Contains method allows you to determine whether a specific object belongs to the item collection. This method is used internally when assigning arbitrary data to the ComboBoxEdit.SelectedItem property. You will rarely need to call Contains within your code.
The following code snippet (auto-collected from DevExpress Examples) contains a reference to the Contains(Object) method.
