推荐答案
Simple
Specifies that the list is always visible and that the text portion is editable. This means that the user can enter a new value and is not limited to selecting an existing value in the list.
DropDown
Specifies that the list is displayed by clicking the down arrow and that the text portion is editable. This means that the user can enter a new value and is not limited to selecting an existing value in the list. When using this setting, the Append value of AutoCompleteMode works the same as the SuggestAppend value. This is the default style.
DropDownList
Specifies that the list is displayed by clicking the down arrow and that the text portion is not editable. This means that the user cannot enter a new value. Only values already in the list can be selected. The list displays only if AutoCompleteMode is Suggest or SuggestAppend.
因此，术语DropDownList通常用于描述具有DropDownList下拉样式的组合框，即具有不可编辑文本字段的组合框
Therefore the term DropDownList is often used to describe a combobox with a drop down style of DropDownList, i.e. a combobox with a non-editable text field
