推荐答案

听起来像是焦点问题:

当用户按下Enter键时，您的文本框将显示一些详细信息.

我想，TextBox在此过程中得到了关注.将焦点转移到TextBox会将其从ListView中删除.因此，键盘输入不会对ListView产生任何进一步的影响.

显示详细信息后，文本框是否具有焦点?如果是这样，您应该能够使用箭头键在TextBox内移动光标.
好消息是，如果TextBox具有焦点，则可以通过
将其移交给ListView.

Sounds like a problem with the focus:

When user presses Enter, your TextBox displays some details.

I suppose, the TextBox gets focus in the process. Transferring focus to the TextBox removes it from the ListView. Therefore keyboard input doesn''t have any further influence on the ListView.

Does the TextBox have focus after displaying details? If so, you should be able to move the cursor around within the TextBox using the arrow keys.
The good news is that if the TextBox has focus, it can hand it over back to the ListView via

listView1.Focus();

紧接在文本框中显示详细信息的代码部分之后.

right after the code part that displays details in the TextBox.
