如何禁用将用户值键入 Windows 表单组合框的选项？
How to disable option of typing user values to Windows Forms Combobox?
我有 winforms 组合框。我有我放入 Items 集合中的预定义值列表。我想让用户只选择这个值，而不是输入他们自己的值。
我该怎么办？
将其 DropDownStyle 设置为 DropDownList
将 属性 DropDownStyle 设置为 ComboBoxStyle.DropDownList
comboBox1.DropDownStyle = ComboBoxStyle.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.
