不，没有这样的控制权。从可用性的角度来看，组合框是不适合功能性的从n中选择m个项目。我建议使用CheckedListBox控件或者启用带有
复选框的ListView控件。
请注意，有一些组专门用于.NET窗体开发的
microsoft.public.dotnet.framework.windowsform s组层次结构，用于
示例microsoft.public.dotnet.framework.windowsforms.co ntrols，其中
讨论侧重于Windows窗体控件开发。

再次使用herf，你只提供由于缺乏ui
开发经验而被覆盖的意见。一个带有可检查物品的下拉式组合框是一个很好的想法，当一个人被屏幕房地产限制时...即
手持设备和较小的屏幕设备如坚韧的书或其他触摸屏
接口用于pos开发等。
a更多有用的评论本来建议继承一个
checkedlistbox或listview到用户定义的控件中，这样他就能得到他所描述的
。不要试图用他们*想要*做什么来讨论他们*你想他们应该做什么！

我已经学习了几年的用户界面设计和人机交互......
a下拉组合框可检查的项目是一个
*精彩*的想法
不适用于标准Windows窗体。在Windows中，组合框在用户选择了
项后关闭。如果用户有可能选择多个项目，则控件的下拉部分必须保持打开状态，以提供良好的用户体验。但是，这会导致Windows提供的控件集之间出现不一致/行为。
当一个人受到屏幕不动产的限制时......即<手持设备和较小的屏幕设备，如硬拷贝或其他触摸屏界面开发等等。
我指的是标准Windows窗体。当然，有特殊情况
和设计用于这些情况的用户界面库应该包含
适当的控制与/一致/行为。
a更有帮助的评论可能是建议将
checkedlistbox或listview继承到用户定义的控件中，这样他就能得到他所描述的内容。不要试图用他们*想要*做什么来讨论他们*他们应该做的事情！
有时最好不提供解决方案...

Hi,
I want to have a single line combo box dropdown, but where i can selected
multiple items in the drop down via a check box...
I can see one in the standard tool box... is there one ?
If not any suggestions as to where to get one from.
Thanks

No, there is no such control. From a usability perspective comboboxes are
not suitable for the functionaliy "selection of m items out of n". I
suggest to use a CheckedListBox control or a ListView control with
checkboxes enabled instead.
Note that there are some groups devoted to .NET Windows Forms development in
the "microsoft.public.dotnet.framework.windowsform s" group hierarchy, for
example "microsoft.public.dotnet.framework.windowsforms.co ntrols", where
discussion focuses on Windows Forms control development.

again herf, you offer only oppinion that is blanketed by lack of ui
development experience. a drop-down combobox with checkable items is a
*wonderful* idea when one is simply limited by screen real-estate...i.e.
handhelds and smaller screened devices like toughbooks or other touch screen
interfaces for pos development, etc..
a more helpful comment would have been to suggest inheriting a
checkedlistbox or listview into a user-defined control so he can get what
he''s describing. don''t try to talk op''s out of what they *want* to do with
what you *think* they should do!

I have studied User Interface Design and Human-Computer Interaction for
several years...
a drop-down combobox with checkable items is a
*wonderful* idea
Not for standard Windows Forms. In Windows, the combobox closes after an
items is selected by the user. If the user should have the possibility to
select more than one item, the dropdown part of the control must remain
opened to provide a good user experience. However, this would lead to
/inconsistent/ behavior between the set of controls provided by Windows.
when one is simply limited by screen real-estate...i.e.
handhelds and smaller screened devices like toughbooks or other touch
screen
interfaces for pos development, etc..
I was referring to standard Windows Forms. Sure, there are special cases
and user interface libraries designed for use in these cases should contain
appropriate controls with /consistent/ behavior.

checkedlistbox or listview into a user-defined control so he can get what
he''s describing. don''t try to talk op''s out of what they *want* to do with

Sometimes it''s better not to provide a solution...
