Hi,
I search for this problem since two weeks and I make it but it didn't work.
The code of my web site is:
1. web.config
<configuration>
<connectionstrings>
<add name="constring" connectionstring="Data Source=.;Initial Catalog=employee;UID=;PWD=">
providerName="System.Data.SqlClient"/>
<system.web>
<compilation debug="false" targetframework="4.0">
<assemblies>
<add assembly="System.Design, Version=4.0.0.0, Culture=neutral, PublicKeyToken=B03F5F7F11D50A3A">

Please any one help me
推荐答案
尝试使用pagemethods通过javascript ononkeypress或onchangeevent of text box。
try using pagemethods through javascript on "onkeypress" or onchange" event of text box.
