推荐答案

我想你可能会对自动完成TextBoxes，ComboBoxes和ListBoxes感到有些困惑。自动完成TextBox无法按照您的建议运行。不需要提供KeyDown事件;只是自动完成将提供的条目列表。该列表可以是动态的。请参阅MSDN文章https://msdn.microsoft.com/en-us/library/system.windows.forms.textbox.autocompletemode(v = vs.90）.aspx。

I think you may be a little confused by autocomplete TextBoxes, ComboBoxes, and ListBoxes. An autocomplete TextBox does not operate the way you suggest. No KeyDown event needs to be provided; just the list of entries that autocomplete will provide. That list can be dynamic. See the MSDN article https://msdn.microsoft.com/en-us/library/system.windows.forms.textbox.autocompletemode(v=vs.90).aspx.

我认为您需要在文本框中实现自动填充数据。使用AJAX自动完成扩展程序来解决这个问题。
