[DataRepeater] 数据分页，分页存储过程（未完待续-删除功能）
已完成： datarepeater 数据分页，分页控件实现。ajax+jquery 无刷新 更新数据。
未完待续： 数据删除，数据校验。
知识点和问题总结:
datarepeater datasourceid 指定数据源id; sqldatesource 数据源控件 设置connectstring,selectcommand;
<asp:TextBox runat="server" Text='<%# Eval('name')%>' / >
<input type='text' value= '<%# Eval('name')%>' / >
<td class='<%# Eval('name')%>' ></td>
<%=变量名%> html元素直接用服务器变量值
($.ajax 的contextType:application/json -传json数据； dattype:json-获取json数据)；
若传的data为非json 格式数据，则会报错；而且为空的话，则默认发送contextType: application/x-cc-formed
webservice.asmx 加上 [System.Web.Script.Services.ScriptService] 才能保证获取json数据和返回json数据
加上后 return "abc"，则返回的是{"d":"sdf"},客户端 result.d才是真正的json数据
居然alert(json.d)提示未defined ，原来是jquery版本有问题，更新秤1.4.1就OK了，法克啊！！
success: function(json) { var value =jQuery.parseJSON( json.d); if (value.successed == 1) { alert("更新成功") } },
1. 数据源（SQLDataSource 控件），DataRepeater控件指定SOURCEID。
会产生大量ViewState消息。
使用label控件
Aspx
<tr>
<td ><span id="repProduct_ctl61_city">city</span></td>
<td><span id="repProduct_ctl61_Label1">name</span></td>
<td><span id="repProduct_ctl61_Label2">10</span></td>
</tr>
<tr>
<td ><span id="repProduct_ctl62_city">city</span></td>
<td><span id="repProduct_ctl62_Label1">name</span></td>
<td><span id="repProduct_ctl62_Label2">10</span></td>
</tr>
<tr>
<td ><span id="repProduct_ctl63_city">city</span></td>
<td><span id="repProduct_ctl63_Label1">name</span></td>
<td><span id="repProduct_ctl63_Label2">10</span></td>
</tr>
28.40 KB 的源文件。。。
将ASPX：labell服务器控件换成
<td ><input type="text" value='<%# Eval("city") %>' /></td>
同样的数据，查看源代码 VIEWSTATE 变得很少了，页面大小变为 21.74 KB。可见label服务器控件产生了
将近7KB 的 ViewState。 如果更多数据，那多么恐怖。
上面的数据源 直接指定 SQLdatasource 数据源控件， 查询的是 所有数据，但是我们不可能在一页里面展示所有数据。
所以要分页获取数据， 例：第一页 获取 10条记录， 第二页获取 10-20条的记录。
这样，我们需要 传参数给 存储过程： PageSize 页大小，PageNum 第几页，表名，字段名等。。。
配合下面存储分页存储过程，获取指定页面
1: --select top(pagesize) from tablename where [fieldname]<
2: -- (select min FROM
3: -- (select top pagesize*(pagenum-1) [@FieldName] from tablename
4: -- order by xx) as temp
5: -- ) order by xx
6: --select top(10) from
7: -- select * from wowo
8: --set 变?量?，?变?量?大?小?写?，?变?量?不?加?[xx]
9: --CREATE PROCEDURE getPage
10:
11: Alter PROCEDURE getPage
12: @TableName varchar(255),
13: @FieldName varchar(255),
14: @PageSize int =0,
15: @PageNum int ,
16: @OrderType bit =0, --0默?认?升?序?
17: @strWhere varchar(2000) =''
18:
19:
20: as
21:
22: declare @strSQL varchar(6000) --主?语?句?
23: declare @strTmp varchar(6000) --临?时?变?量?
24: declare @strOrder varchar(500)
25:
26:
27: if(@OrderType!=0) --降?序?
28: begin
29: set @strOrder= ' order by '+@FieldName+''
30: set @strTmp=' <(Select min '
31: End
32:
33: else
34: begin
35: set @strOrder=' order by '+@FieldName+' '
36: set @strTmp=' >(select max '
37: End
38:
39: if(@strWhere!='')
40: begin
41: set @strWhere=' where '+@strWhere
42: end
43: else
44: begin

56: exec (@strSQL)
57: Go
58:
59:
60: exec getPage 'wowotuan_miaosha','pid',5,4,1,'pid<147'
上面的存储过程，没获取总记录数的参数，故修改下面这样
--select * from wowotuan_miaosha
--select top(pagesize) from tablename where [fieldname]<
-- (select min FROM
-- (select top pagesize*(pagenum-1) [@FieldName] from tablename
-- order by xx) as temp

--select top(10) from

--CREATE PROCEDURE getPage
Alter PROCEDURE getPage
@TableName varchar(255),
@FieldName varchar(255),

至此已经实现 Repeater控件的数据绑定，分页数据的获取以及 页数状态的变化和控制！
下面将实现 Ajax 更新数据，删除数据。 ajax 请求要更新的json格式数据，webservice获取json数据，并返回json数据。
($.ajax 的contextType:application/json -传json数据； dattype:json-获取json数据)
