AutoComplete

?????????? AutoComplete

:显示文本框扩展功能,当在文本框输出内容时会随机出现一此字符,如IE中的输出网址,如果你在以前输入过这个网址,只要在输入前几个字母就好了,但以代码需要再修改才能实现

1.??? 在TextBox中属性中的ace/serverPath加入WebService.asmx,ServerMethod中介入GetCompletionList(),CompletionInterval 100影响时间为0.1秒,MinimumPrefixLength介入1,最少介入的字符数

2.??? AutoCompleteExtender绑定MyAuto
