.Net 文本框实现内容提示的实例代码(仿Google、Baidu)
1.Demo下载：
文本框实现内容提示(仿Google、Baidu).rar
2.创建数据库、表（我用的sqlserver2008数据库）
CREATE TABLE Ceshi
(
id VARCHAR(50) PRIMARY KEY NOT NULL,
cname VARCHAR(30)
)
GO
INSERT INTO Ceshi
SELECT NEWID(),'jack1' UNION
SELECT NEWID(),'jack2' UNION
SELECT NEWID(),'jack3' UNION
SELECT NEWID(),'jack4' UNION
SELECT NEWID(),'jack5' UNION
SELECT NEWID(),'peter1' UNION
SELECT NEWID(),'peter2' UNION
SELECT NEWID(),'peter3' UNION
SELECT NEWID(),'peter4' UNION
SELECT NEWID(),'peter5'
go
create function [dbo].[f_GetPy](@str nvarchar(4000))
returns nvarchar(4000)
as
begin
declare @strlen int,@re nvarchar(4000)
declare @t table(chr nchar(1) collate Chinese_PRC_CI_AS,letter nchar(1))
insert into @t(chr,letter)
select '吖 ', 'A ' union all select '八 ', 'B ' union all

select @strlen=len(@str),@re= ' '
while @strlen> 0
begin

from @t a where chr <=substring(@str,@strlen,1)
order by chr desc

end
return(@re)
end
