首先来看看效果

1.项目中添加AjaxTextBox.dll的相关引用

2.Web.Config配置文件

<?xml version="1.0"?>
<!--
Note: As an alternative to hand editing this file you can use the
web admin tool to configure settings for your application. Use
the Website->Asp.Net Configuration option in Visual Studio.

<configuration>
<appSettings/>
<connectionStrings/>
<system.web>
<!-- AjaxPro.dll -->
<httpHandlers>
<add verb="POST,GET" path="ajaxpro/*.ashx" type="AjaxPro.AjaxHandlerFactory, AjaxPro"/>
</httpHandlers>
<!--
Set compilation debug="true" to insert debugging
symbols into the compiled page. Because this
affects performance, set this value to true only
during development.
-->
<compilation debug="true" targetFramework="4.0"/>
<!--
The <authentication> section enables configuration
of the security authentication mode used by
ASP.NET to identify an incoming user.
-->
<authentication mode="Windows"/>
<!--
The <customErrors> section enables configuration
of what to do if/when an unhandled error occurs
during the execution of a request. Specifically,
it enables developers to configure html error pages
to be displayed in place of a error stack trace.

<customErrors mode="RemoteOnly" defaultRedirect="GenericErrorPage.htm">
<error statusCode="403" redirect="NoAccess.htm" />
<error statusCode="404" redirect="FileNotFound.htm" />
</customErrors>
-->
</system.web>
</configuration>

3.业务数据处理AjaxUtility.cs

using AjaxPro;

/// <summary>
/// Summary description for AjaxUtility
/// </summary>
public class AjaxUtility
{
public AjaxUtility()
{
//
// TODO: Add constructor logic here
//
}

[AjaxMethod()]
public static ArrayList GetSearchItems(string query, string type)
{
ArrayList items = new ArrayList();

//可根据 query 、type 参数进行条件查询，获得不同结果返回
/*
* eg:所有记录为：111111、123123、123456
* 数据库查询: LIKE '%...'
*/
items.Add("111111          111111");
items.Add("123123          123123");
items.Add("123456          123456");

return items;
}

[AjaxMethod()]
public static DataTable GetCustomerInfo(string customerCode)
{
DataTable dt = new DataTable();
dt.Columns.Add("name");
dt.Columns.Add("age");
dt.Columns.Add("address");

DataRow row = null;

if (customerCode.Trim() == "123123")
{
row = dt.NewRow();
row["name"] = "ZhangSan";
row["age"] = "25";
row["address"] = "SH";
dt.Rows.Add(row);
}
else
{
row = dt.NewRow();
row["name"] = "WangWu";
row["age"] = "27";
row["address"] = "BJ";
dt.Rows.Add(row);
}

return dt;
}

}
