突然间想到百度和GOOGLE的AJAX模糊查询的功能。那就COMBOX中能不能实现呢？
查看资料
在数据源中多了一个
<
Proxy
>
<
ext
:
HttpProxy
Method
=
"POST"
Url
=
"Plants.ashx"
/>
</
Proxy
>
估计是异步的东东。本人才浅
先建立一个
<%@ WebHandler Language="C#" Class="DataHandler" %>
using System;
using System.Web;
using System.Collections.Generic;
using Ext.Net;
using System.Data;
public class DataHandler : IHttpHandler {
public void ProcessRequest(HttpContext context)
{
if (!string.IsNullOrEmpty(context.Request["query"]))
{
string query = context.Request["query"];
context.Response.ContentType = "text/json";
DataTable table = new DAL.UserDAO().WorkNoList(query).Tables[0] ;
List<UserInfo> lst = new List<UserInfo>();
foreach (DataRow row in table.Rows)
{
UserInfo user = new UserInfo();
user.UserName = Convert.ToString(row["name"]);
//user.UserId = Convert.ToInt32(row["workno"]);
user.UserId = Convert.ToString(row["workno"]);
lst.Add(user);
}
string json = Ext.Net.JSON.Serialize(lst);
context.Response.Write(json);
}
else
{
context.Response.ContentType = "text/json";
DataTable table = new DAL.UserDAO().WorkNoList().Tables[0] ;
List<UserInfo> lst = new List<UserInfo>();
foreach (DataRow row in table.Rows)
{
UserInfo user = new UserInfo();
user.UserName = Convert.ToString(row["name"]);
//user.UserId = Convert.ToInt32(row["workno"]);
user.UserId = Convert.ToString(row["workno"]);
lst.Add(user);
}
string json = Ext.Net.JSON.Serialize(lst);
context.Response.Write(json);
}
}
public bool IsReusable
{
get
{
return false;
}
}
}
public class UserInfo
{
private string _UserName;
public string UserName
{
get { return _UserName; }
set { _UserName = value; }
}
private string _UserId;
public string UserId
{
get { return _UserId; }
set { _UserId = value; }
}
}
看看效果吧
