关于Repeater的分页问题
--------------------编程问答-------------------- 现在都是用aspnetpage控件分页的，很简单除非真的是需要自己写代码分页，不然还是用存储过程加aspnetpage控件分页，方便也效率的 --------------------编程问答-------------------- 使用aspnetpage控件 分页 可以很简单的就实现了
百度可以找找例子 --------------------编程问答-------------------- 给你个俺写的简单repeater分页例子

存储过程
--------------------编程问答--------------------
create PROCEDURE [dbo].[pagination]
@tblName varchar(255), -- 表名
@strGetFields varchar(1000), -- 需要返回的列
@fldName varchar(255), -- 排序的字段名
@PageSize int, -- 页尺寸
@PageIndex int, -- 页码
@OrderType varchar(4), -- 设置排序类型, 非 0 值则降序
@strWhere varchar(1500), -- 查询条件 (注意: 不要加 where)
@rowCount int output --查询到的记录数
AS
declare @strSQL varchar(5000) -- 主语句
declare @strTmp varchar(110) -- 临时变量
declare @strOrder varchar(400) -- 排序类型
declare @strCountTmp nvarchar(100) --记录数
declare @timediff datetime --耗时
begin
select @timediff = Getdate()
if @strWhere !=''
set @strCountTmp = 'select @rowCount = count(*) from [' + @tblName + '] where '+@strWhere
else
set @strCountTmp = 'select @rowCount = count(*) from [' + @tblName + ']'
exec sp_executesql @strCountTmp,N'@rowCount int out',@rowCount out --输出总记录数
if @OrderType != 'asc'
begin
set @strTmp = '<(select min'
set @strOrder = ' order by ' + @fldName +' desc'
--如果@OrderType不是0，就执行降序，这句很重要！
end
else
begin
set @strTmp = '>(select max'
set @strOrder = ' order by ' + @fldName +' asc'
end
if @PageIndex = 1
begin
if @strWhere != ''
set @strSQL = 'select top ' + str(@PageSize) +' '+@strGetFields+ ' from [' + @tblName + '] where ' + @strWhere + ' ' + @strOrder
else
set @strSQL = 'select top ' + str(@PageSize) +' '+@strGetFields+ ' from ['+ @tblName + '] '+ @strOrder
--如果是第一页就执行以上代码，这样会加快执行速度
end
else
begin
--以下代码赋予了@strSQL以真正执行的SQL代码
set @strSQL = 'select top ' + str(@PageSize) +' '+@strGetFields+ ' from ['
+ @tblName + '] where [' + @fldName + ']' + @strTmp + '(['+ @fldName + ']) from (select top ' + str((@PageIndex-1)*@PageSize) + ' ['+ @fldName + '] from [' + @tblName + ']' + @strOrder + ') as tblTmp)'+ @strOrder
if @strWhere != ''
set @strSQL = 'select top ' + str(@PageSize) +' '+@strGetFields+ ' from ['

end
exec (@strSQL)
select datediff(ms,@timediff,GetDate()) as runtime
楼猪写的太复杂了,看的偶都头大;还是简单点好了.
--------------------编程问答-------------------- 我主要是想用PagedDataSource给Repeater分页。可是总报错。不知问题出在哪里？
执行时不报错，点击下一页和末页时报错，无反应。
提示对话框：Microsoft JScript runtime error: Object doesn't support this property or method
下面是调试时的停顿处，最后到theForm.submit(); 处停止
<script type="text/javascript">
//<![CDATA[
var theForm = document.forms['form1'];
if (!theForm) {
theForm = document.form1;
}
function __doPostBack(eventTarget, eventArgument) {
if (!theForm.onsubmit || (theForm.onsubmit() != false)) {
theForm.__EVENTTARGET.value = eventTarget;
theForm.__EVENTARGUMENT.value = eventArgument;
theForm.submit(); }
}
//]]>
</script>
--------------------编程问答-------------------- 建议用aspnetpage分页。我有一个datalist分页的程序，手写的代码。给你参考下
前台.aspx：
<asp:DataList ID="DataList4" runat="server" Width="548px">
<ItemTemplate>
<div style="text-align: center">
<table border="0" cellpadding="0" cellspacing="0" style="width: 100%">
<tr>
<td style="width: 40px" align="center">
<asp:Image ID="Image8" runat="server" ImageUrl="~/Images/20.jpg" /></td>
<td style="width: 400px" align="left">
<a href="viewnews.aspx?id=<%#Eval("id") %>">
<asp:Label ID="Label4" runat="server" Text='<%# Eval("title") %>'></asp:Label>
</a>
</td>
<td style="width: 148px">
[<asp:Label ID="Label5" runat="server" Text='<%# Eval("pub_date") %>'></asp:Label>]</td>
</tr>
</table>
</div>
</ItemTemplate>
</asp:DataList></td>
</tr>
<tr><td style="height:50px" valign="middle" align="center">
<asp:Label ID="Label9" runat="server" Text="当前页码为："></asp:Label>[
<asp:Label ID="labPage" runat="server" Text="1"></asp:Label>
]
<asp:Label ID="Label8" runat="server" Text="总页码为："></asp:Label>
[
<asp:Label ID="labBackPage" runat="server"></asp:Label>
]<asp:LinkButton ID="lnkbtnOne" runat="server" Font-Underline="False" ForeColor="Red" OnClick="lnkbtnOne_Click"
>第一页</asp:LinkButton>
<asp:LinkButton ID="lnkbtnUp" runat="server" Font-Underline="False" ForeColor="Red" OnClick="lnkbtnUp_Click"
>上一页</asp:LinkButton>
<asp:LinkButton ID="lnkbtnNext" runat="server" Font-Underline="False" ForeColor="Red" OnClick="lnkbtnNext_Click"
>下一页</asp:LinkButton>
<asp:LinkButton ID="lnkbtnBack" runat="server" Font-Underline="False" ForeColor="Red" OnClick="lnkbtnBack_Click"
>最后一页</asp:LinkButton>
后台.aspx.cs代码：
public void list4()//公司新闻
{
OleDbConnection conn = ConnectionDB.getCon();
OleDbCommand cmd = new OleDbCommand("select id,title,pub_date from product where pro_name='news' order by id desc ", conn);
OleDbDataAdapter dsa = new OleDbDataAdapter(cmd);
DataSet ta = new DataSet();
dsa.Fill(ta);
int cutPage = Convert.ToInt32(labPage.Text);//当前显示页页
PagedDataSource ps = new PagedDataSource();//page数据源
ps.DataSource = ta.Tables[0].DefaultView;//page数据源的绑定
ps.AllowPaging = true;//设为能分页
ps.PageSize = 20;//每页显示的记录数
ps.CurrentPageIndex = cutPage - 1;//获取当页面
lnkbtnUp.Enabled = true;
lnkbtnNext.Enabled = true;
lnkbtnBack.Enabled = true;
lnkbtnOne.Enabled = true;
if (cutPage == 1)
{
lnkbtnOne.Enabled = false;//不显示第一页
lnkbtnUp.Enabled = false;//不显示上一页
}
if (cutPage == ps.PageCount)
{
lnkbtnNext.Enabled = false;//不显示下一页
lnkbtnBack.Enabled = false;//不显示最后一页
}
labBackPage.Text = Convert.ToString(Convert.ToInt32(ps.PageCount));//总页码数
DataList4.DataSource = ps;
DataList4.DataBind();
}
protected void lnkbtnOne_Click(object sender, EventArgs e)
{
labPage.Text = "1";
list4();
}
protected void lnkbtnUp_Click(object sender, EventArgs e)
{
labPage.Text = Convert.ToString(Convert.ToInt32(labPage.Text) - 1);
list4();
}
protected void lnkbtnNext_Click(object sender, EventArgs e)
{
labPage.Text = Convert.ToString(Convert.ToInt32(labPage.Text) + 1);
list4();
}
protected void lnkbtnBack_Click(object sender, EventArgs e)
{
labPage.Text = labBackPage.Text;
list4();
}
--------------------编程问答-------------------- 我用的方法基本和6#的差不多呀，可是就出问题，所以找不到原因？ --------------------编程问答-------------------- --------------------编程问答-------------------- 一般直接用的就是微软的分页，不过据说用ajax分页效果最好！
补充：.NET技术 , ASP.NET
