解决方案

尝试代码

展开 | < span class =codeLinkonclick =selectAll（this）;>选择 | Wrap | 行号

当你说：
@maliksleo


你在吗？想要在ListBox中显示3个值吗？

如何向ListBox添加项目？

< blockquote>我认为他说他有一个包含多项选择的列表框。但是想要将它限制在不超过3个。


Maliksleo：如果这听起来是正确的，请使用SelectedIndicesChanged事件，并与已经选择的项目数进行比较。

i have a list box now i want to select 3 values in it through VB code

and restrict the user to select onle three values please help me

Regards

解决方案

Try code

Expand|Select|Wrap|Line Numbers

Could you please elaborate on what you mean when you say:
@maliksleo
Do you only want 3 values to appear in the ListBox?
How are you adding items to your ListBox?

-Frinny

I think he''s saying he has a listbox with multiple selection, of many items. But wants to restrict it to no more than 3.

Maliksleo: If that sounds right use the SelectedIndicesChanged event, and compare to the number of items already selected.
