推荐答案

我确实决定回答问题，尽管我不确定您想要实现什么...

可能您想根据顶级复选框的状态启用一些其他功能，例如:

[]平方与TO
| ------ ----------	[]交货购买到
| -------- --------	[]交货至TO
[x]交货至
| ----------------	[x]平方掉购买TO
| ----------------	[x]平方掉卖至

首先，在codeproject网站上阅读一些文章.也许您会找到答案.
将CheckedListBox作为下拉列表的ComboBox [ ^ ]
具有高级下拉功能的自定义组合框 [ ^ ]
CCheckComboBox II [此 [ ^ ]讨论，您将在其中找到可在CheckedListBox的ItemCheck事件中使用以使项目禁用的示例代码.

但我建议您使用 treeview [ ^ ]控件，对您来说更灵活，因为它具有节点和子节点，可以显示为复选框.

我发现了一些额外的东西！ [

I did decide to answer question, though i''m not sure what you want to achieve...

Probably you want to enable some extra functionality depend on status of top level checkbox, for example:

[ ] Squared Off TO
|----------------	[ ] Delivery Buy TO
|----------------	[ ] Delivery Sell TO
[x] Delivery TO
|----------------	[x] Squared Off Buy TO
|----------------	[x] Squared Off Sell TO

First of all, read some articles on codeproject site. Maybe you''ll find an answer.
A ComboBox with a CheckedListBox as a Dropdown[^]
Custom ComboBoxes with Advanced Drop-down Features[^]
CCheckComboBox II[^]

Similar functionality to CheckedComboBox has a CheckedListBox control. Take a look at this[^] discussion, where you''ll find a sample code that can be used in the ItemCheck event of a CheckedListBox to make items disable.

But i recomend you to use treeview[^] control, which is more flexible to you, becouse it has nodes and childnodes, which can be displayed as checkboxes.

I found something EXTRA! Here[^] you''ll find an article about: How to hide checkbox of the certain TreeNode in TreeView control.

I hope it will be helpful.
