为什么TextChanged不使用AutoPostBack [英] Why TextChanged not using AutoPostBack
本文介绍了为什么TextChanged不使用AutoPostBack的处理方法，对大家解决问题具有一定的参考价值，需要的朋友们下面随着小编来一起学习吧！
问题描述
我有这个TextBox，用户可以在其中执行搜索之前先输入内容.键入时，程序会将它们与从数据库中获取的某些值进行比较.
因此，我尝试将TextChanged事件处理程序与UpdatePanel一起使用，并将AutoPostBack设置为true.
但是，除非您实际执行诸如单击按钮之类的回发操作，否则它不会起作用.
知道我该如何实现吗?
谢谢.
Hi,
I have this TextBox where users will type things before performing a search. As they type, the program compares them with some values fetched from the database.
So I was trying to use the TextChanged event handler with UpdatePanel and AutoPostBack turned to true.
But it doesn''t work unless you actually perform a postback like click a button.
Any idea how I can achieve this?
Thanks.
推荐答案
刚刚找到此 [ ^ ]，是的，它只会触发当您退出时.
至于使用CSS设置文本框的格式(样式)，请在此处使用几个示例 [<一个带有源代码和在线编辑器的href ="http://www.cssportal.com/form-elements/text-box.htm" target ="_ blank" title ="New Window"> ^ ] .
如果您不反对jQuery方法，那么我的博客上有大量示例(单击sig).
干杯.
Just found this[^], so, yeah, it only fires when you tab out.
As for formatting (styling) the textbox with CSS, here''s a couple of samples[^], with source, and an online editor.
If you''re not opposed to the jQuery approach, I have a ton of samples on my blog (click sig).
Cheers.
我知道我本身并没有回答您的问题，但这仍然可以解决问题.
有什么原因不能使用自动填充 [
I know I''m not answering your question per se, but this might still solve the problem.
Is there any reason you can''t use the Autocomplete[^] control?
It''s free, and the scripts are on the MS CDN.
Cheers.
