I have a CSV file which holds various items. Some of these items I put into a combobox. How can I put a newline and/or tab in the CSV file so it will show up as a newline/tab inside the combobox? I have tried and but it just shows those in the combobox.

推荐答案

基础 ComboBox 不支持显示这样的特殊字符，它们将被忽略.如果您需要这种类型的功能，您需要覆盖 OnDrawItem 方法并自己绘制这些项目 - 我不建议这样做.另一种选择是使用来自 Telerik 或 Infragistics 等公司的更高级的 ComboBox.

The base ComboBox doesn't support special characters like this for its display, they will simply be ignored. If you need this type of functionality you'll need to override the OnDrawItem method and draw those items on your own - I do not recommend this. Another option would be to use a more advanced ComboBox from a company like Telerik or Infragistics.
