问题描述
我要问的问题已经问过(甚至回答)位置:
的
I'm asking the question already asked (and even answered) here:Why are some textboxes not accepting Control + A shortcut to select all by default
不过,这个问题的答案并不为我工作。我有这样的代码:
But that answer doesn't work for me. I have this code:
public class LoginForm : Form
{
private TextBox tbUsername;
public LoginForm()
{
tbUsername = new TextBox();
tbUsername.ShortcutsEnabled = true;
tbUsername.Multiline = false;
Controls.Add(tbUsername);
}
}
文本框显示出来,我可以写在上面,我可以剪切,复制和粘贴文本它没有任何问题。
但当我尝试按 CTRL + A
我只听到金光闪闪类似,你听到的,如果你试图从一个空的文本框擦除文字金光闪闪(您的浏览器地址栏中尝试)。
The textbox shows up, I can write on it, I can cut, copy and paste text on it without any problems.But when I try to press ctrl+a
I only hear a "bling" similar to the bling that you hear if you try to erase text from an empty textbox (try it with your browser's address bar).
推荐答案
像其他的答案表明, Application.EnableVisualStyles( )
应该叫。另外, TextBox.ShortcutsEnabled
应设置为真正
。但是如果你的 TextBox.Multiline
已启用然后按Ctrl + A将无法正常工作(适用的)。使用的RichTextBox
反而会得到解决的问题。
Like other answers indicate, Application.EnableVisualStyles()
should be called. Also the TextBox.ShortcutsEnabled
should be set to true
. But if your TextBox.Multiline
is enabled then Ctrl+A will not work (see MSDN documentation). Using RichTextBox
instead will get around the problem.
