推荐答案

您可以在文本的某个位置加上一个省略号，并且当用户将鼠标悬停在它上面时，您可以将整个文本显示为工具提示.

但是，如果需要在ListView单元中显示大量数据，也许您应该重新考虑您的总体设计.

You could put an elipse at some point in the text, and when the user hovers over it, you could display the entire text as a tooltip.

HOWEVER, if you need to display that much data in a ListView cell, maybe you should re-think youre overall design.

实际上，它是259 ...来自MSDN. :"ListViewItem的文本不应超过259个字符，否则可能会发生意外的行为."

我想说，试图在ListView中显示许多字符将使ListView不是控件的最佳选择.

Microsoft建议，如果要显示所选项目的文本，请在表单中添加一个文本框，当用户选择一个新的listviewitem时，请使用超过259个字符的列文本填充该文本框.或者，您可以使用工具提示...这是一个非常简单的解决方案.

或使用其他人创建的自定义列表视图，例如: http://www.codeproject.com/KB/list /aa_listview.asp [^ ]

actually, it''s 259...from MSDN: "The text of the ListViewItem should not exceed 259 characters or unexpected behavior could occur."

I would say that trying to display that many characters in a ListView would make the ListView not the best choice of control.

Microsoft suggests that if you want to show the text for a selected item, then add a textbox to the form and when the user selects a new listviewitem, populate the textbox with the text of the column that exceeds 259 characters. Or, you can use a tooltip...that''s a pretty simple solution.

Or use a custom listview that someone else has created such as: http://www.codeproject.com/KB/list/aa_listview.asp[^]
