突出显示文本框中的文本 [英] Highlight text in textbox

问题描述

我要突出显示文本框中的文本.当用户在文本框中键入任何内容时，应在文本框中的文本周围生成一个彩色框.我不确定是否可以在普通文本框中执行此操作，或者我必须为此使用富文本框.

我已经在yahoo邮件中看到了这件事.当我们尝试编写新邮件并在收件人"字段中添加收件人时，联系人姓名周围会出现一个框.

请提示..
谢谢

I want to highlight text in text box. When user types anything in textbox a colored box should generate around text in textbox. I am not sure if I can do this in normal textbox or I have to use Rich text box for this.

I have seen this thing in yahoo mail When we are trying to write new mail and we add recipients in "To" field, a box appears around contact name.

Kindly suggest..
Thank you

如果上述讨论没有帮助，则您需要使用RichTextBox来获得所需的行为，因为普通文本框具有一定的局限性.

Whatever close possible in ASP.NET is discussed here, see if anything discussed is inline of what you need: Highlight text in Textbox using JavaScript[^]

If above discussion does not help then you need to use RichTextBox to get your desired behaviour as normal textbox has certain limitation.
