文本框被一个巨大的字符串禁用

问题描述

textbox 在输入大字符串时遇到问题.

I'm having a issue with a textbox when it's typed a huge string.

在我的例子中，文本框用于编写电子邮件地址，并且没有字符限制.所以，我做了这个测试:我在记事本中写了 200 个电子邮件地址，然后我将文本粘贴到 textbox 上，文本消失了，但是如果我改变控件的焦点，文本再次显示.我已经看到了这个 链接，但它没有帮助我.我已经尝试将 MaxLength 属性更改为 0 (微软说怎么做)，但在这里也不起作用.

In my case, the textbox is used to write email addresses, and it doesn't have a limit of chars. So, I've made this test: I wrote 200 email addresses in a notepad, and I pasted the text on the textbox and the text disappeared, but if I change the focus of the control, the text is displayed again. I already saw this link, but it doesn't helped me. I already tried to change the MaxLength property to 0 (how the microsoft says to do), but it doesn't worked here too.

考虑到一个包含 50 个字符的电子邮件地址，MaxLength 属性不会有问题，因为 200 个电子邮件地址乘以 50 个字符(每封电子邮件)，我将有 10000 个字符，并且 TextBox 的默认值.MaxLength 为 32767.

Considering a email address with 50 chars, the MaxLength property wouldn't be a problem, because 200 email addresses multiplying with 50 chars (each email), I'll have 10000 chars, and the default value of TextBox.MaxLength is 32767.

而且，在你询问代码之前，我只将文本设置为字符串.

And, before you ask for the code, I only set the text to a string.

myEmailObject.Address = txtEmail.Text;

我应该使用 RichText 还是什么?

Should I use RichText, or what?

推荐答案

尝试将 Multiline 属性设置为 True 并增加文本框的高度

Try to set the Multiline property to True and increase the height of the textbox
