推荐答案

您是什么意思要导航"它们?

如果要检查它们的值，可以在按钮单击事件处理程序中简单地对其进行遍历.

what do you mean you want to "navigate" them?

If you want to check their values, you could simply iterate through them in the button click event handler.

您是否尝试过类似的操作:

Have you tried something like:

if (e.KeyChar == ‘\r’)
{
e.Handled = true;
System.Windows.Forms.SendKeys.Send("{TAB}");
}

覆盖表单的OnKeyUp或覆盖ProcessKeyTab ...

顺便说一句，你说:

Override the form’s OnKeyUp or override ProcessKeyTab...

Btw, you say:

看了您到目前为止提出的问题.发现只有一个标记为接受的答案！

Looked at the questions you had asked till now. Found only one marked as answer accepted!

当人们在没有实际测试答案是否有效的情况下将答案扔到那里时，我会喜欢它.

我假设您是说您要用户输入textbox，当他们按下Enter键时，它将带他们到下一个textbox，对吗?

覆盖表单的OnKeyUp将不起作用，因为如果您位于textbox中，则表单的OnKeyUp不会触发，因为它没有焦点.

但是，首先，请确保所有textbox都已为所需顺序设置了正确的TabIndex.然后，只需为textbox KeyUp事件编写一个进程，然后在KeyData中检查Keys.Enter.如果它是Enter键，则可以执行System.Windows.Form.SendKeys.Send("{TAB}").然后，只需将该进程处理程序添加到您要处理的每个textbox es中即可.

I love it when people throw answer out there without actually testing if it will work.

I assume that you''re saying that you want the user to be typing in a textbox and when they hit enter, it takes them to the next textbox, correct?

Overriding the form''s OnKeyUp will not work because if you are in a textbox, the form''s OnKeyUp won''t fire because it doesn''t have the focus.

But, first, make sure that your textboxes all have the correct TabIndex set for the order you want. Then, just write a single process for a textbox KeyUp event and check the KeyData for Keys.Enter. If it is the enter key, then you can do the System.Windows.Form.SendKeys.Send("{TAB}"). Then, just add that process handler to each of the textboxes that you want it to handle.
